As we approach a new season, The Met Office is advising homeowners to check whether their properties are in flood-prone areas, charge their phones and make a 'flood plan'. As such, our thoughts naturally turn to the heavy rainfall associated with the colder months and how to protect our buildings from the consequences.
In this month's issue, we speak with Steve McSorley, a Chartered Engineer with over 35 years of experience at Perega, about designing flood-resilient buildings in the UK. Here, he discusses key considerations throughout the process – from regulatory requirements to water management – and explains that for architects, engineers and developers, the challenge is clear: To create buildings that can withstand and quickly recover from flooding and protect communities – all while reducing costs in the process. Turn to page 34 for the full article.
Elsewhere in this edition, the Benholm Group explores how biophilic design offers measurable returns on investment, enhances productivity, reduces operating costs and improves overall building value in modern construction projects – see page 22 Abby Robinson, Biodiversity Team Leader at CSX, a leading nature-based solutions provider, discusses the importance of biodiversity-rich habitats in brownfield sites for our ecosystems on page 20 . We also take a look at Corstorphine & Wright's design for The Scoop, a unique concave office building in Southwark, London. Turn to page 12 for more information.

Protection without structural weakening
Protection is required where cavity insulation terminates partway up a gable.
A conventional approach results in the masonry triangle bearing on a DPC slip plane. Leeward wind suction can cause failure across the gable, seehttps://www.bbc.co.uk/news/uk-england-dorset-57253967

CONLON GROUP BECOMES AN EMPLOYEE-OWNED BUSINESS
Preston-based Conlon has announced a significant milestone in the business’ history. Conlon Holdings, including Conlon Construction, has moved from family ownership to an Employee-Ownership Trust (EOT). This change in ownership follows months of planning by the board of directors and the Conlon family. The construction company was established in 1961, when the ‘founding fathers’ – the five Conlon brothers – were working on a road project called The Preston Bypass, which we all now know as the M6. From these roots, the company, then known as Conlon Brothers, quickly developed a reputation for reliable and timely work with a strong and loyal customer base.

ANNOUNCES
CONSTRUCTION MILESTONE IN TAIWAN
ACPV ARCHITECTS Antonio Citterio Patricia Viel, the Milan-based architecture and interior design practice, recently celebrated a significant milestone with the groundbreaking ceremony for its latest project in Taiwan – the Capella Kenting resort development commissioned by Riant Capital and Capella Hotels and Resorts.
ACPV ARCHITECTS
Located in the southernmost county of Taiwan, just north of the scenic Kenting National Park, the resort embodies the Capella Hotel Group’s holistic vision, prioritising guest experience and creating a strong sense of belonging to the place.
To highlight Kenting, the architects will seamlessly integrate more than 60 villas and related amenities within the natural landscape. By mirroring the contours and slopes of the lush green environment, they will deliberately optimise views of the sea and sky, ensuring that each villa boasts panoramic vistas of the ocean. This organic connection with nature begins on arrival, when guests are greeted by a sunken drop-off area flooded with natural light and greenery.
W hile offering a connection to nature, Capella Kenting remains a social space, striking a balance between privacy and interaction.
A rchitect Antonio Citterio, Chairman and Co-Founder of ACPV ARCHITECTS, describes the concept as centred on the interplay between the building site and the sea. He says: “Every architectural detail is meticulously crafted to provide uninterrupted views of the water and horizon, granting guests a sense of unity with nature.”
A rchitect Patricia Viel, CEO and Co-Founder, further explains: “The resort’s design draws inspiration from the rich cultural context of the location. For our first resort in Taiwan, we are integrating traditional craft and construction techniques, including low stacked-stone walls, to minimise visual impact while paying homage to aboriginal culture.”

ECD ARCHITECTS
IS AN ASSOCIATE DIRECTOR AND REGIONAL HEAD OF SUSTAINABILITY AT ECD ARCHITECTS
Tell us about your career journey. How did you get started in the field of architecture? It wasn’t something I always dreamed of. Even though I always enjoyed art and making things, I didn’t even take art for GCSE. I was contemplating studying engineering or medicine, but then my mother suggested architecture might be like engineering, while allowing me to be more creative. After a week of work experience and a summer school at Wimbledon School of Art – both of which I really enjoyed – I was sold.
Were there any pivotal moments or experiences that solidified your decision to pursue a career in architecture and design?
The work experience I did helped massively. I particularly enjoyed the studio environment, the team briefed me to create a model, which was then taken into a real-life client meeting. Maybe for me, the bigger pivot has been moving into a more sustainability-focused role. This has been more of a slow transition, but as I became more aware of the urgency of the climate crisis, it started to feel wrong to just carry on as if there isn’t a problem.
If you hadn’t followed your passion for being an architect, what other career path would you have pursued?
I seriously considered engineering and becoming a doctor. In a way, my role now is quite ‘engineering-esque’ at times, but I’m happy with my choice. It turns out that within architecture, there are so many routes you can take. However, if I just got to do something fun, I’d quite like to make hats.
Who has been your greatest influence and source of inspiration?
There are so many. Architects and other construction professionals who are interested in sustainability tend to be a really lovely bunch who want to share for the benefit of each other and the planet. I’m lucky to have great current colleagues, as well as inspiring past colleagues and to be part of a group of architecture ‘heads of sustainability’, all of whom support each other – now that is inspiring.
What’s been the most memorable project you’ve worked on?
I lived in New Zealand for a few months and helped to build a timber tiny house on a trailer. It’s not what I normally do, but it was such a change and obviously memorable being outside, nailing and sawing, overlooking the town of Wanaka, and popping down to the lake for a swim after work; pretty much heaven!
Can you share a personal anecdote or experience that taught you a valuable lesson about being an architect? During COVID, I lived with my parents in Yorkshire for a while. It was great, but very removed from the projects I was working on in London. Designing on the computer started to feel a bit like playing a computer game. And then I went back to London and went to a home that we were going to retrofit and talked to the residents and it all seemed purposeful again. Without people involved, our buildings are pretty pointless!
Could you walk us through a typical workday in your current role?
It’s so varied, which I love. It might involve working on energy models using the Passivhaus Planning Package, working out where the energy inefficiencies of an existing building are and how that can be addressed. I could be doing this alongside colleagues in London, Glasgow or our new Preston office.
LIZZY WESTMACOTT
It’s really rewarding seeing reactions from clients and residents when we update them on our energy-efficiency solutions and how we can reduce the carbon emissions in their buildings.
I also get to stick my nose into other people’s projects, exploring ways to make them more sustainable. I love the chats where we’re bouncing exciting ideas off each other, which lead to better outcomes.
What is your favourite building?
Neues Museum in Berlin is a wonderful example of bringing an old building back to life. The evident care and understanding that allow the new and old to be seen is something beautiful and an inspiration for how we retrofit buildings.
In your opinion, who is the greatest architectural mastermind of our time?
I don’t think it’s one person. I think it’s the hive mind of lots of people trying really hard, often in their own time, to make buildings more energy efficient, resilient and comfortable. So instead of a person, I’m picking LETI, the Low Energy Transformation Initiative, which demonstrates how enthusiastic people can collaborate to educate others and actually change client briefs and Government policy.
If you were hosting a dinner party to discuss architecture and design, and you could invite three individuals, either from the past or the present, who would you choose to join your conversation?
I moved to Glasgow just over a year ago, and I’d like to chat to Alexander ‘Greek’ Thomson, about what he thinks about how Glasgow’s changed and what opportunities there are for its future.
I’d also invite Rachel Carson, the Author of ‘Silent Spring’, to talk about being a relatively early environmental activist and what inspired her and how we can make change happen.
And Barnabas Calder, whose book, ‘Architecture from Prehistory to Climate Emergency,’ talks about the relationship between energy, architecture and society in an original way and I hope helps to frame where we go from here.
Looking ahead, what exciting projects or initiatives can we anticipate from you in the coming year? We are working with a collaboration of local authorities to see how we can most efficiently understand the steps they need to take to decarbonise their non-domestic buildings and, crucially, how this can be integrated with their ongoing maintenance plans.
We are making great headway in the north of England specifically, where there are many opportunities to improve social housing and bring energy-efficiency upgrades to thousands of homes.
This year, I’m also collaborating with a friend from another practice to start a Scotland Heads of Sustainability group; it’s so enlightening to share the knowledge, support and inspiration we’ve both been lucky enough to have at our respective practices.

CORSTORPHINE & WRIGHT UNVEILS INNOVATIVE CONCAVE OFFICE BUILDING
Leading UK architecture firm Corstorphine & Wright has announced the completion of The Scoop, a unique concave office building in Southwark, London. The innovative design reuses an existing building and integrates a conical cut-out facade in white-glazed bricks, creating a playful and novel response to the site’s context and neighbouring church.
Si tuated in the vibrant Union Street conservation area, the building stands as a testament to modern architecture while respecting the heritage of its surroundings, namely the adjacent Grade II-Listed Church of Most Precious Blood, whose circular window is now strikingly framed. The nearby Union Theatre, Jerwood Space and Flat Iron Square further add to the rich cultural setting of the building.
T he design retains the significant southern-facing and corner return of the existing facade, blending it seamlessly with a new-build extension. This detailed approach ensures a successful integration into the neighbourhood, adding to the area’s creative and artistic reputation. Working closely with the forwardthinking, community-minded building owner, ThomsonHillsBalfour (THB), Corstorphine & Wright has created a truly unique building, which is captivating passers-by following its recent unveiling.
D avid Crosthwait, Director at Corstorphine & Wright, comments: “The whole team is proud and excited to share this project. The design of the scooped facade has allowed the building to be extended out in front of the church through a symbiotic relationship that protects and enhances the prominence and visibility of the church while providing
a one-of-a-kind office headquarters. It was important for us to honour the cultural and historic context of the area, and respect the neighbouring church building, ensuring its visibility and reverence. The resulting building is a carefully orchestrated balance, allowing its neighbours to shine, whilst also shining itself and adding to the vibrant architectural and cultural variety of the area.
“ None of this would have been possible without the vision and support of our client, who embraced the project and stuck with it through its challenges. It’s a great accomplishment to reach this point, and we feel the finished result is a testament to the role that bold design can play in enhancing our city.”
T he client and building owners are delighted with the finished results. “Creating unique office spaces in a thoughtful and sustainable way was of huge importance both to us and our conscientious, forwardthinking tenants, MMGY Global. We wanted to enable the teams working in the spaces to enjoy their environment and feel proud to be considering the local community, residents and businesses when developing the project,” says Amanda and Peter HillsBalfour and Steve and Sarah Thomson of THB.

FROM SHOPPING TO GATHERING: HEATHERWICK STUDIO’S NEW DESIGN FOR SEOUL’S HANWHA GALLERIA
Hanwha Galleria, a famous shopping centre in Seoul, will be given a Heatherwick studio makeover following a competition to reimagine six sites in the South Korean capital. The brief asked for a design that will challenge conventional notions of a luxury department store and affirm the country’s increasingly influential role as a global cultural powerhouse.
Designing with 150mm wall cavities allows you the freedom to specify the best insulation for your build.
And when energy requirements tighten in 2025, you’ll already be ahead of the curve. Don’t be constrained by 100mm cavities. Stay flexible with 150mm DriTherm® Cavity Slab 32.
knaufinsulatio n .co.uk / housebuilders-hu b
Hanwha Galleria lies at a major crossroads, framing the Han River in the distance. Located in the Apgujeong-dong neighbourhood in Seoul, the project acts as a focal point between the residential and the shopping districts of Gangnam and responds to the city’s vision to revitalise the Han Riverbanks. The studio proposed a design that redefines the store’s connection to the local area. Unlike a traditional, inward-facing shopping centre, the proposal uses the facade and the areas around it as public spaces, which are accessible to all, whether they are shopping at the mall or simply enjoying the area.
Neil Hubbard, Partner and Group Leader at Heatherwick studio, says: “Traditionally, department stores are quite inward facing; they feel closed off to the surrounding streets. But here we have an important intersection in Apgujeong with two buildings, east and west, that felt like an opportunity to bring people together. Combined with Hanwha’s ambition to bring more activity to the buildings, we wanted to provide a strong overall silhouette that creates a gateway, but also gives Seoulites new garden-like spaces to meet, shop and enjoy their city.”
The galleria consists of two symmetrically-opposed twin buildings – alike but not identical – which are connected underneath by a subway. Above, their silhouettes resemble rippled hourglasses, where on the inside, the narrower necks act as nature-filled public spaces. On the ground level, the twins’ unusual shapes come together to frame the view of the river when looking both through and between the buildings.
A s visitors ascend the redesigned existing subway, the airy, light-filled entrance atria draw them into two landscaped plazas on the ground level. Their journey continues to an open mid-level garden dotted with cafes, restaurants and shops. The new plantfilled open rooftops offer another green space and, paired with the glass facade, they provide multiple viewpoints and reflections of the city. The outdoor spaces are designed to provide natural interest throughout the year with a choice of native plants and careful landscaping.
B oth buildings have a double-layer skin, which offers better sustainability credentials whilst also creating a canvas for art exhibitions and events. The crystalline glass exterior of the buildings creates an impression of softness as it glistens in the day. At night, the
outer skin comes alive when used as a backdrop for glowing projections.
T he studio’s design for the site was selected as part of competition organised by the Seoul Metropolitan Government. Together with the local authorities and Haeahn Architecture, it will now work on the detailed design and development of the project.
T he project follows the recent announcement of the appointment of Thomas Heatherwick, the studio’s Founder, as General Director of the fifth edition of the Seoul Biennale of Architecture and Urbanism, to be held in 2025. The Korean edition of Thomas’ book, Humanise: A Maker’s Guide to Building Our World, will be published later this year

THE HIDDEN VALUE OF HERITAGE: ENHANCING WELLBEING THROUGH PRESERVATION
With much made about the value of our heritage assets up and down the country, Terry Moran from renaissance engineers examines some of their less well-known benefits.
As a Chartered Engineer who’s been working with heritage structures for nearly 10 years, I could talk all day about the value of heritage. At a basic level, it’s a question with several obvious answers.
For one, heritage buildings are a portal into our past, offering us a chance to understand our history and embrace it in our everyday lives. Whether it’s an Edwardian building in the centre of Manchester refurbished into modern office space or a beautiful stone-built terrace house in Saltaire, these are both examples of open-air museums that map the evolution of the architectural form across the country.
I f that’s not enough for you, our industry is moving rapidly towards a healthier relationship with carbon. As a result, we’re incentivised to adapt and reuse our current building stock instead of building more. Making use of the carbon already invested within heritage assets built decades or even centuries ago is much preferable to expending more on a new build.
A nd, what about the not-so-obvious benefits? Do heritage structures improve our wellbeing? Now that’s a more difficult question and one where the
answer is likely to be more nebulous. Of course, there’s the wellbeing that comes from living in a good-quality home or working in a safe and properly fittedout office, but this can be true whether the building is a historic Grade II-Listed building or brand new.
L et’s be clear, does heritage promote wellbeing in and of itself? If a recent study by Historic England is anything to go by, it does.
Wellbeing and the built environment
Wellbeing is difficult to quantify, especially when trying to establish its source. However, given the negative effects of poor wellbeing on people’s health and the resulting dampening effect it has on the economy, there’s good reason to design our buildings to be wellbeing compliant. That is, measured against a standardised scale to ensure the net result of their erection is a boost to wellbeing.
O ur places, both rural and urban, can have positive and negative effects on wellbeing. In rural settings, where green space is abundant, air quality is good and congestion non-existent, it’s widely recognised that the effect on wellbeing
IS A CHARTERED STRUCTURAL ENGINEER FROM RENAISSANCE ENGINEERS
is a net positive. By contrast, city living in high-density urban areas tends to have the opposite effect on wellbeing across nearly every metric. Does that mean all structures are detrimental to our wellbeing?
The positive correlation between heritage assets and wellbeing
I n the report, ‘Cultural Heritage Capital and Wellbeing: Examining the Relationship Between Heritage Density and Life Satisfaction,’ Historic England provides convincing evidence for a positive correlation between living close to heritage assets and wellbeing. If replicable, these conclusions could provide useful insights into how we can pivot our urban planning strategies to make the most of heritage assets.
D istilling the findings, the main takeaway is that there’s a statistically significant, positive relationship between the density of cultural heritage assets near a person’s residence and their self-reported life satisfaction. That is, in simpler terms, the more heritage assets near where you live, things like listed buildings, scheduled monuments and historic parks, the greater your level of wellbeing is likely to be.

The economic implications
T he report also quantifies the economic benefits of cultural heritage density by translating improvements in life satisfaction into monetary terms using the WELLBY (Wellbeing Adjusted Life Year) approach. It finds that a 1% increase in the density of heritage assets within a 1km radius of residences is associated with a small but meaningful rise in life satisfaction.
Happy and healthy people with a greater sense of wellbeing tend to be more productive, work harder and earn more. The percentage of their wellbeing that comes from proximity to heritage has been valued at a net boost of £29bn to the economy.
Learning from the results
We already have robust policies in place when it comes to working with heritage structures. Whatever the structural or architectural intervention we make on these assets, we work with the structure rather than against it, delivering considered designs that are both noninvasive and geared towards preserving the history present for future generations to enjoy.
B ut there’s more to be learned from the findings here than simply to continue with business as usual.
Impact on planning for residential developments
W hen it comes to designing new residential developments, positive weight should be given to the planning applications when there is a high density of heritage assets close by. Not only will the potential wellbeing of the eventual residents be higher because of the placement of the new residences but there is a concrete economic benefit, too.
I ncentivising the regeneration of dilapidated or derelict heritage assets
Working with heritage structures can be difficult for many different reasons. For a start, you’re often constrained on what you can do from a planning perspective. What’s more, where heritage structures are in poor states of repair, significant remedial or stabilising works may be required before work can begin on the building’s transformation. In many situations, this can limit the commercial viability of a project, which has the potential to turn developers away.
N ow this is a speculative point, as the study doesn’t differentiate between heritage assets in good states of repair and those that are derelict. But if we
make the reasonable assumption that the former have a greater effect on wellbeing than the latter, there’s a good argument for incentivising the refurbishment of heritage assets in poor states of repair. This wouldn’t be unreasonable given the clear economic benefits these assets have according to the WELLBY approach. What form this incentivisation takes, and from which body of Government, is another question. However, if the results coming out of the analysis by Historic England hold weight, it seems clear that heritage assets falling into disrepair is a missed opportunity for our communities and our economy.

PIECING TOGETHER MOSAIC HABITATS TO HELP BROWNFIELD LAND DIVERSITY
With the ongoing discussions in the UK’s construction sector about which sites are best to develop, many fail to recognise the biodiversity-rich habitats in brownfield sites that cannot be found elsewhere. Abby Robinson, Biodiversity Team Leader at CSX, a leading nature-based solutions provider, discusses why these sites are invaluable to our ecosystems.
CSX
Id entifying an Open Mosaic Habitat
T he formation of an Open Mosaic Habitat (OMH) is a natural process where nature is left to develop optimally in a particular space. When land is disused and unkept for long enough, like many brownfield sites in the UK, nature reclaims its dominion and blooms into a diverse ecosystem most conducive to growth.
A t first glance, such a space could be mistaken for a sparsely vegetated, lowquality, low-value habitat, both of which are located on brownfield sites and, to an untrained eye, look deceivingly alike. This often leads to misclassification; however, upon closer examination the differences are stark.
A n OMH is a mosaic of many different small habitats adjacent to one another on a minor scale, creating a larger mosaic habitat. The variety comes from multiple changes in soil and topography within a small area, allowing biodiversity to flourish. For an area to be classed as an OMH, it must meet the requirements of the UK Habitat classification system, which includes several specific criteria.
D ue to the wide range of wildlife that this classification includes, and the close proximity of different habitats, OMH are naturally very biodiverse and, therefore, extremely valuable in forming unique ecosystems – often more so than greenbelt grasslands, which are populated mostly with a low variety of wildlife and poor vegetation diversity such as weeds.
Difficulties in replacing an OMH
W ith biodiversity net gain (BNG) regulations now fully enforced, all future developments need to remediate any damage or changes caused to habitats during construction. However, because OMHs form naturally, they are difficult to replicate artificially, often resulting in a shortfall of the net gain requirement.
A further challenge is that many of the species found in a mosaic habitat cannot thrive elsewhere. Previously developed land often has unique soil and substrate influenced by minerals, extraneous materials or other residues from past disturbances. Therefore, transplanting the same species to a nearby location is often unviable and not a like-for-like substitute.
Implications for developers
Ultimately, if an area is not correctly classified, it can result in significant financial losses, wasted time and potential reputational damage for a developer, as well as harm to a unique habitat or ecosystem if it is disturbed in the process. To avoid this, comprehensive, objective data, such as drone monitoring, should be used to give an accurate representation of the whole area. This minimises the risk of mischaracterising sites when relying solely on an ecological walk-over assessment conducted in the field.
N umerous variables can impact the accuracy of an ecological assessment. OMHs are vitally important and contain wildlife rarely found elsewhere in the UK. In comparison to some greenbelt grasslands with minimal variety, it is why it is being seen as crucial that such biodiversity-rich brownfield environments are protected or replaced where necessary. This can be achieved through accurate classification and reliable data, which we believe is best obtained through drone monitoring.

BIOPHILIC DESIGN: BEYOND AESTHETICS
AI might be the buzzword of the moment, promising to revolutionise the way we work and live, but there’s a much more traditional approach that offers measurable returns on investment, enhances productivity, reduces operating costs and improves overall building value in modern construction projects. Biophilic design, which integrates natural elements into built environments, is not merely an aesthetic trend but a strategic investment yielding measurable financial returns.
BENHOLM GROUP
Understanding biophilic design
Biophilic design finds its roots in biophilia, a term coined by Biologist E.O. Wilson to describe the inherent human affinity for nature. This design philosophy incorporates elements such as natural materials, light, vegetation and water features into architectural and interior designs. By reintroducing these elements into urban environments, biophilic design aims to reconnect people with nature and enhance their quality of life.
Boosting productivity
One of the most compelling arguments for biophilic design is its positive impact on productivity. A landmark study, 'The Relative Benefits of Green Versus Lean Office Space: Three Field Experiments', provides robust evidence for these claims. This research compared green offices, which include plants and natural light, with lean offices lacking these elements. The findings were remarkable: Productivity in green offices increased by 15%.
Employees in green offices reported higher levels of concentration, increased job satisfaction and overall improved wellbeing. These factors collectively contribute to enhanced performance and efficiency. The study underscores that the presence of natural elements in the workplace can foster a more conducive environment for employees, leading to tangible productivity gains.
Health benefits
Biophilic design also offers significant health benefits, increasingly supported by scientific research. A notable study conducted between Natural Resources Institute Finland and two major Finnish universities, published in Scientific Reports, highlighted the health advantages of indoor green walls. The study found that such walls can improve skin quality and immune function in office workers within a month.
This research involved 28 office workers in urban environments, revealing that those working near green walls experienced an increase in beneficial skin bacteria. These bacteria help fend off pathogens and inflammation, enhancing the immune system’s overall resilience. This indicates that green walls contribute not only to visual and psychological wellbeing but also to physical health, making them a valuable addition to workspaces.
Financial benefits and return on investment
The financial implications of biophilic design are substantial and well documented. The Reap What You Sow research project offers a comprehensive analysis of the financial returns of integrating natural elements into workspaces. This study demonstrated that introducing
nature and greenery can enhance environmental and wellbeing benefits by up to 200%, equating to approximately £22,000 per employee.
For real estate developers and clients, this financial aspect is crucial. The ability to measure and monetise the wellbeing and environmental value of biophilic design allows stakeholders to evaluate the worth of these investments alongside traditional project costs.
Reducing operating costs
Biophilic design contributes to reducing operating costs in several ways. One primary method is through its impact on employee health. Healthier employees take fewer sick days and incur lower healthcare costs. Natural light, a key element of biophilic design, improves sleep patterns, reduces stress and enhances overall health, leading to fewer absences and higher productivity. Additionally, incorporating natural ventilation and plants can improve indoor air quality, creating a healthier work environment.
The effect of plants on indoor air quality was famously tested in NASA’s Clean Air study, which found that certain plants can effectively remove toxins like formaldehyde, benzene and trichloroethylene from indoor air. This not only reduces the likelihood of respiratory issues but also supports employees’ wellbeing and cognitive function.
Energy savings are another significant benefit. Buildings designed to maximise natural light reduce dependence on artificial lighting, thereby lowering energy consumption. Green roofs and walls provide natural insulation, reducing heating and cooling expenses. These operational savings accumulate over time, reinforcing the financial prudence of biophilic design.

Enhancing building value
Biophilic design not only reduces costs but also enhances the overall value of buildings. Properties that integrate natural elements are more attractive to tenants and buyers, resulting in higher occupancy rates and rental values. The improved wellbeing and productivity of occupants contribute to better tenant retention and satisfaction.
The Reap What You Sow study emphasises the importance of capturing the comprehensive impact of design on financial outcomes. By linking design quality to wellbeing and financial benefits, architects and developers can present a stronger business case for biophilic design. The study used both qualitative and quantitative measures to evaluate the benefits, providing a financial proxy for wellbeing that is easy for decision makers to understand.
Embracing a new way of building and designing
Biophilic design is much more than an aesthetic trend; it is a strategic investment that yields measurable returns. By promoting productivity, reducing operating costs and improving building value, biophilic design creates environments that are not only beautiful but also economically advantageous. As evidence from studies like The Relative Benefits of Green Versus Lean Office Space and Reap What You Sow shows, incorporating nature into our built environments is a smart choice for modern construction projects. Embracing biophilic design means embracing a future where spaces are designed to enhance both human wellbeing and financial performance.

FUNCTIONALITY, VISIBILITY AND SUSTAINABILITY: THE SIMPLER APPROACH TO SPECIFICATION
With a greater number of materials, decors and finishes available to specifiers than ever before, the ease at which the right match can be found for their commercial projects has become increasingly important. However, certain obstacles can impede this process, including the ease of sourcing decors with the desired finishes, a lack of readily-available technical information and an understanding of what product finishes are available. George Emms, Sales Leader UK & Ireland –Specification at Polyrey, part of Wilsonart UK, explores how these issues can be resolved.
Th e move from office-based working to working-fromhome or hybrid models has upended business practices across all industries, including architectural and interior design specifications. Its long-term impact on professional development continues to unfold in unexpected ways, including knowledge pooling. Where once architects and interior designers would sit in the same office and use each other’s expertise to fill potential knowledge gaps, working from home has reduced access to this invaluable communal resource.
T hough this is nobody’s fault, the impact of this on a project is clear – especially for more junior employees taking their first, formative steps in the sector.
In areas requiring specialist knowledge such as surface specification, the inability to easily consult more experienced colleagues may lead to the specification of lower-quality or poorly-suited materials.
F inding functionality
T his knowledge vacuum is further compounded by the continuing phaseout of the librarian role within architecture practices. Previously, this role was invaluable to architects looking for specific material samples or product information. However, as the price of property continues to rise, many practices simply do not have the floorspace to maintain a library and, by extension, employ a librarian to maintain it.
This is not a situation architecture practices can fully control, but the impact remains the same – a loss of key support mechanisms during the surface specification process. Surfaces can already present concerns for architects and interior designers, with an often-overwhelming level of options available. Multiple factors have to be considered depending on the application, including durability, ease of maintenance and what specific product properties are required.
T his to say nothing of other less obvious but still vital surface characteristics, such as their light reflectance value. These details cannot be overlooked, as each surface – whether a wall, door or worktop – plays a vital function within the overall building. However, awareness of these factors can be lost without easy access to resources previously offered by experienced colleagues and librarians.
Having to hand a readily-available reference guide that clearly provides key technical data and product information to the reader will help support the specifier in making an informed decision. In an industry where knowledge gaps can have a major impact in securing alternative materials, for example, if a fabricator informs an architect mid project that a specified surface is not available in a certain decor, looking to the manufacturer for assistance can help save time and money.
S eeking simplicity
This expertise is instrumental in streamlining the surface selection process. While maintaining awareness of product data may be more challenging given today’s agile working culture, leveraging supply chain support can allow greater clarity and simplicity – a vital requirement throughout the decision-making process.
Furthermore, it is beneficial if architects and interior designers include their appointed surface provider into the project’s documents as standard to assist with any technical or availability questions the fabricator or installer may have. This approach allows the specifier to remain focused on the project at hand. Engaging a
supplier that can offer RIBA-accredited CPDs on this topic is, therefore, critical to ensuring continued compliance and an easier decision-making process when selecting surfaces.
Going green
The need for peace of mind over product information is further underlined by the growing focus on sustainable products in building design. Indeed, sustainability has moved from a preference to a priority over the past decade. Yet though this is clearly welcome, the relative newness and fast-changing nature of environmental regulations may present difficulties around remaining compliant during surface specification. Greenwashing also remains a topic of concern, with unprovable product claims further muddying the waters over which products are actually made using sustainable methods, technologies and materials.
In these circumstances, it is again vital that architects and interior
designers look to their supply chain to educate and simplify what is required in each specific product category.
S ustainability-related data should be easily available for all surfaces, including product passports that list full and clear material composition, such as the three pillars – comfort and health, natural resources and circularity – plus a product’s total carbon footprint cost from manufacture to transport.
I n conclusion, changing working practices risk the creation of potential knowledge vacuums for architect and interior design specification firms. To address this on a project-by-project basis, company stakeholders should look to their suppliers as more than a manufacturer of surfaces and panels. By instead viewing them as a trusted advisor, any awareness gaps can be filled and selection processes simplified.

GORDON HINES
IS THE UK TECHNICAL MANAGER FOR SFS GROUP FASTENING TECHNOLOGY
SECURING RAINSCREEN SYSTEMS FOR LONGEVITY AND STRUCTURAL INTEGRITY
FC&A hears from Gordon Hines, the UK Technical Manager for SFS Group Fastening Technology, about best practice in relation to specifying the appropriate mounting solutions for rainscreen systems in new-build and retrofit situations.
S ecuring rainscreen systems for longevity and structural integrity
A s a highly-experienced specialist in the creation and development of rainscreen cladding support systems, as well as carbon and stainless-steel fastening solutions, SFS Group enjoys excellent working relationships with many of the industry’s major panel manufacturers, as well as leading installation specialists and architectural practices. As a consequence, the company has had a pioneering role in the development of the new-generation fixing solutions that have facilitated the trend towards the construction of taller buildings, accordingly dealing with progressively more challenging loading conditions.
The company’s UK Technical Manager, Gordon Hines, explains: “Rainscreen systems are nowadays being used in situations where they would not previously have been
considered; morphing from a solution to overclad two- and three-storey structures to a situation where they are now regularly specified on very tall buildings, up to 30 storeys high, where they are subject to much greater wind and other load conditions.
“Therefore, they need to be very robust to achieve the longevity – the performance and the appearance that property owners and occupiers demand – and that requires proper analysis of the conditions, sub structure and the nature of the cladding panel in order to achieve the right solution.”
S FS Group Fastening Technology’s support for specifiers extends from delivering multiple RIBA-certified CPD seminars to its SFS ConnectSuite online tools and the highly-experienced technicians in Gordon’s team, who undertake hundreds of pull-out tests for clients every year to determine the strength and suitability of walls as well as roof decks.
SFS GROUP FASTENING
G ordon continues: “Whether fastening into steel or timber studs or some type of masonry, the fixings need to be covered by an ETA providing the independently-tested values. However, with masonry or concrete, although there might be ETAs available, it is generally regarded as good practice to conduct a pull-out test on site to verify the substrate. It also needs to be noted that all fixings within a rainscreen system are not operating in a fully dry environment, so they need to be of the appropriate quality depending on the material used in the subframe. As most are fabricated from aluminium, then the fixings ought to be A4 stainless steel to ensure the best long-term performance.
“ Then, as the work of the subframe is unseen, the fixings from that to the panels are often overlooked. It is important for fixings to be approved by the panel manufacturer – or OEM –as being suitable, while the fixing suppliers should conduct widespread testing to ensure everything is fit for purpose. Each panel type has its own limitations and these, together, with the allowance for movement, need to be factored into the way these are attached to the subframe.”
Accommodating movement is key
W hile the need to allow for structural deflection and thermal movement is implicit in UK design codes, for rainscreen cladding, it is crucial to understand where the fixed points are, and also the positions where sliding movement can best be accommodated, if serious problems are to be avoided in hot weather. Decorative cladding panels can be subject to buckling or can actually snap if the design and calculations are wrong.
G ordon recounts: “What we have been finding lately is not related to the actual retention of fixings within the structure of the wall but with movement across the subframe of various rainscreen systems. As a result, we are regularly being asked to investigate facades that have had to be stripped back, and clients often don’t realise that we need full access in terms of scaffold or hydraulic platforms in order to carry out tests at multiple locations across a building’s elevations in order to get a clear picture of what is occurring. Then, we can advise the client or designer with our recommendations on remedial works to ensure an installation does not encounter similar
issues in the future. Our preference generally is to establish the fixed point for a rainscreen system in the middle of a wall and allow thermal movement to take place at either end, which is good practice and actually reduces the amplitude of movement.
F inally, Gordon turned his attention to the potential pitfalls associated with the secret fixing of panels. He concludes: “Fibre cement panels are very popular at the moment and can be face or secret fixed. Secret fixing, which features TUF-S-type fixings, requires a lot of testing, as the further into the panel a fixing is embedded, the better the test results. Unfortunately, though, this also increases the chance of ghosting of the panel fixings, showing their position on the face as the panel dries after being rained on. Some manufacturers do a lot of expansion testing as well to prevent cracking of the facade. Then, with face fixing, the head size, pull through and allowance for expansion all need to be factored into the choice of fixing type. After all this testing and work, it is vital that the panels are fixed to each manufacturer’s recommendations.”

WATERPROOFING BALCONIES: KEY CONSIDERATIONS FOR LIQUID SPECIFICATION
Wayne Chissell, Technical Director at WestWood, discusses the specification of liquid-applied membranes for waterproofing balconies and how to maximise performance and aesthetics.
As an integral part of a building’s facade, a balcony has both architectural and functional purposes. Exposed to the elements and, in many cases, foot traffic, a balcony must be highly durable while offering an aesthetic appearance that complements interior and exterior spaces.
T he waterproofing system plays a crucial role in achieving these aims for both refurbishment projects and new constructions. Choosing a liquid-applied membrane ensures a robust solution that can be easily installed in confined areas, including around details such as railings and upstands. Providing protection from chemicals, UV radiation, heat and water ponding, the technology can also be used to create a skid-inhibiting finish as well as different colours, styles and patterns.
L iquid-applied membranes are available in a variety of chemistries, so there are several factors to consider before making a choice. Polymethyl methacrylate (PMMA) is one of the most popular for balconies as it can meet installation, performance and aesthetic requirements.
Cold applied, a PMMA-based liquid resin is compatible with most substrates. The liquid is mixed with a peroxide catalyst or activator on site to trigger the curing process. For balcony applications, the build up would comprise of a primer, a reinforced waterproofing system and a self-levelling mortar. This process creates an ultrasmooth surface prior to the installation of finishing layers that can create many different textures, colours and designs.
Design flexibility
To meet aesthetic requirements, PMMA can be matched to any RAL colour and a variety of special finishes achieved.
As part of the system build up, coloured chips or quartz sand can be added to the wearing layer. These decorative finishes also provide greater slip resistance. Thanks to the vast colour options that can be generated using PMMA technology, intricate patterns and modern tile effects can also be achieved.
A s the cured system is UV resistant, aesthetics are maintained as there is no risk of the membrane fading after the installation is complete.
Minimising disruption
C ompared to other liquid technologies, PMMA is one of the fastest curing, making it ideal for balcony refurbishments in large, occupied buildings such as social housing developments. The process can take as little as 15 to 20 minutes, even at sub-zero temperatures, minimising disruption for residents and reducing the need for temporary access.
When installed correctly by an approved contractor, the PMMA build up offers a long-lasting solution guaranteed for up to 25 years. The chemical structure of PMMA means it is free from plasticisers and has a high tensile strength and elasticity. This ensures the membrane can withstand structural and thermal movements and is highly resistant to UV radiation.
Adding value
T hrough advances in technology, supplementary products have been manufactured for PMMA liquid waterproofing systems that can make balcony refurbishments more efficient and durable.
R apid-curing PMMA screeds and heavy-duty concrete repair mortars (certified to EN 13813), together with ultra-low viscosity substrate stabilisers, enhance the usability of the system, ensuring no compatibility issues if substrate repairs are required during installation. These products also generate significant time savings,

preventing the need to use cementitious alternatives, which can take 28 days to vent out prior to overcoating.
B alcony railings can be made watertight using a reinforced putty. This product is designed for geometrically-complex details that are too small to be sealed using fleece-reinforced liquid waterproofing. Highly flexible and weather resistant, the putty can be installed on most substrates and at extreme temperatures.
Complementing historic architecture
T he renovation of a Grade II-Listed Georgian apartment building demonstrates how PMMA technology can be used for balcony projects. Located in South Kensington, London, the property features a large balcony extending the full length of the facade and comprises more than 100 ornate railings.
T he existing asphalt on the balcony had started to deteriorate and leak, so was removed prior to preparing the substrate. A primer was applied, followed by a PMMAbased waterproofing resin and self-levelling wearing layer.
To achieve a tile effect, a solvent-free, PMMA-based wearing layer was installed in pebble grey that would become the grout lines for the tiles. Masking tape in a width of 6mm was then used to meticulously measure and mark out the tile pattern in sections.
O nce the tape was down, a wearing layer in a darker grey was applied to create the look of the main tile, followed by black and grey chips. These were spread evenly into the resin while it cured.
To ensure watertight junctions at the bottom of each of the railings, reinforced putty was sculpted around each one.
T hese products have ensured the balcony is weather and slip resistant with a tile effect that complements the building’s historic architecture.

MEETING VENTILATION REQUIREMENTS IN INCREASINGLY AIRTIGHT BUILDINGS WITH MVHR
Ruth MacEachern, Product Manager at EnviroVent, looks at how MVHR is helping to meet ventilation requirements in modern homes. ENVIROVENT
Wi thin the construction industry, ‘build tight, ventilate right’ is a well-known energyefficiency principle. This is especially so since Approved Document F (ADF) of Building Regulations updated in 2022 requires increased levels of airtightness and enhanced ventilation rates. The regulation updates, plus the amalgamation of the Domestic Ventilation Compliance Guide meant ventilation became a controlled service, which was a clear signal of the increasing importance of indoor air quality in homes.
A s ADF updates increased the whole dwelling ventilation rate over and above previous requirements, mechanical ventilation with heat recovery (MVHR) became one of the most important ways to achieve this.
A s MVHR provides controlled, filtered fresh air throughout the house, the heat recovered from the internal exchanger is able to reduce the heating demands of occupants and, by supplying the air, also means that no trickle vents are required. Many modern ventilation systems have several grades of filters that prevent harmful bacteria and particulate matter
from entering the property, providing a higher level of indoor air quality.
W ith manufacturers making advances in ventilation technology, this ensures that not only could heat be recovered for energy-saving reasons, but also overheating could be addressed. The introduction of Approved Document O Regulations reinforced the need to avoid potential overheating issues at the design and preconstruction stage, rather than via mechanical ventilation and cooling-focused options once the property is built.
Good design is essential
W hen it comes to MVHR, the design of the system is crucial to the overall efficiency of the building. The BRE Best Practice Guide to the installation and commissioning of MEV and MVHR systems has been instrumental in bringing into play major revisions to ADF, in the areas of installation, ductwork (contamination), filters, noise and Specific Fan Power (in line with SAP Appendix Q). This has driven up industry standards and has been instrumental in ensuring that the installation of ventilation systems is carried out correctly.
Balancing airflow
An important factor in ensuring MVHR efficiency involves checking that the system chosen is correctly sized to ensure balanced airflow throughout the property. The routing of ducts and positioning of ventilation openings must be carefully planned to ensure adequate airflow, particularly in wet rooms, such as the kitchen or bathrooms, while avoiding noise disturbance in living spaces and bedrooms. Airflow must be balanced not just from one room to the next, but it is also important to consider the flow of air entering and leaving a building via external vents.
A study conducted by multidisciplinary building performance expert BPE Specialists states that "only 16% of systems were commissioned correctly with respect to airflow and balancing”. Good practice states that supply and extract airflows should be balanced in accordance with the design requirements and individual room flow rates of the property.
Installation
G ood installation is an essential part of ensuring the effectiveness of this type of ventilation system. A ventilation system that has issues with the ducting, which can
range from ‘slump’ of flexible types in the loft/roof space through to inadequate jointing mechanisms, is always going to underperform. To prevent slump, contractors should ensure that any flexible ducting is only used for final connections. However, some flexible ducting is needed to run from the MVHR unit to isolate ducting and prevent vibration from the unit, as well as ensure that the semi-rigid or rigid ducting is able to marry up with the unit. To mitigate noise transfer, acoustic flex is often recommended here, but, as with all flexible ducting, it should be pulled taught and kept to a minimum.
P oor installation can affect a ventilation unit’s efficiency, power consumption and noise levels. The result could be increased running costs and a negative impact on indoor air quality if the unit is not installed correctly, as well as damage to the ventilation unit. Correct installation should ensure that there is minimal noise and vibration from a unit. For example, antivibration mounts may be required to help reduce noise transfer from wall- or floor-mounted units, often in multi-occupancy dwellings.
M any modern MVHR systems incorporate smart ventilation controls, which provide greater control to the user, as well as optimised energy usage and ease of commissioning for the installer.
Integration into airtight homes
W hile MVHR systems offer numerous benefits, their integration in airtight homes comes with its own set of challenges. Maintaining the integrity of the building envelope is crucial, as any unintended air leakage can compromise the performance of the mechanical ventilation system.
Typically, in newly-constructed buildings, duct leakage can range from 25 to 40% (Source: Department of Energy report), which is unacceptable for highperformance buildings like Passivhaus. To address this challenge, it is essential to ensure correct sealing of ductwork, which should minimise leakage to less than 3% of the system’s air volume. This requires a combination of effective design, quality installation and rigorous testing to achieve optimal airtightness.
Passivhaus
Further tests and checks have to be carried out if ventilation units are being installed in Passivhaus properties. Insulation and seals should be inspected to ensure they are intact and there are no gaps or leaks that could compromise the airtightness of the Passivhaus concept.
P assivhaus, obviously, presents another dimension in the need for energy-efficient ventilation systems. Achieving Passivhaus certification requires meticulous attention to detail in terms of insulation, airtightness, ventilation and overall energy performance. MVHR fits into this framework, providing a comprehensive solution that addresses the requirements of Passivhaus construction. However, ventilation systems must be certified to meet the Passivhaus standard to be part of a Passivhaus build.
I ntegrating mechanical ventilation systems in airtight homes, including Passivhaus buildings, presents both challenges and opportunities for the new-build sector. Effective MVHR system design can go a long way towards addressing the potential challenges posed by airtightness. With the benefit of ventilation systems with heat recovery, airtight buildings can enjoy high levels of indoor air quality, energy efficiency and reduced carbon emissions over the lifetime of the dwelling.
DESIGNING FOR SUSTAINABILITY AND AESTHETICS
Kathryn Tormay, Head of Product at Crown Paints, delves into the latest eco-friendly innovations.
CROWN PAINTS
Quality without compromise
A t a time when sustainability is paramount to winning new business, environmentally-friendly product solutions are more crucial than ever when designing for the built environment.
Finding the right materials that enable you to meet client requirements and deliver a high-quality, long-lasting finish is critical.
It’s therefore vital for manufacturers to take action and offer solutions that not only contribute to the visual aesthetics of spaces but prioritise the wellbeing of our planet.
When it comes to coatings, one of the simplest ways to improve a building’s sustainability credentials is to opt for paint brands that offer low-VOC formulations (volatile organic compounds). VOCs are chemicals that can be emitted as gases from certain solids or liquids, potentially causing adverse health effects and contributing to environmental pollution. Low-VOC formulations ensure that the impact on air quality and human health is minimised, offering a safer and healthier living environment.
L ast year, we introduced Crown Trade Clean Extreme Clean Air, a new low-VOC product that has been certified as meeting BREEAM (Building Research Establishment Environmental Assessment Method) and LEED (Leadership in Energy and Environmental Design) regulations, demonstrating our commitment to producing paints that align with the highest standards in the industry.
C lean Extreme Clean Air is also equipped with innovative technology, which actively contributes to purifying the air within enclosed spaces. By absorbing harmful chemicals like formaldehyde from the surrounding environment, our paints not only provide aesthetic enhancements but also contribute to a healthier indoor atmosphere from the very first coat.
O pting for water-based products, such as our Fastflow Quick Dry range, provides a high-quality alternative to solvent-based paints that will save time and money while still giving the perfect finish.
H owever, preference for sustainable products should by no means equate to a compromise in the quality of their performance. For example, Clean Extreme Clean Air is stain resistant and independently tested to a Class 1 scrub rating. This durability ensures a long-lasting impact and extended maintenance cycle.
Manufacturing for good
B eyond product innovation, the manufacturing process plays a huge role in the sustainability of the construction industry.
A s we move towards Industry 4.0, which will see the next phase of digitisation within the sector, many architects and designers will be searching for manufacturers who are driving this forward.
W hile 2050 might feel a long way off, it’s vital that manufacturers of all sizes begin acting today to reduce their emissions in line with net-zero targets.
We started this journey a few years back and at the end of 2021 opened a new materials and packaging warehouse, alongside installing new machinery and technology into our existing factory.
T his has enabled us to optimise flows within the factory, which makes us more efficient and reduces our overall carbon footprint by reducing energy usage. Through this technology, we are proud that 100% of our owned operations run on renewable energy from certified sources.
A nd we’re not stopping there, we have set ourselves goals to achieve complete carbon neutrality across our own operations by 2026 and reduce greenhouse gas emissions across our entire supply chain by 50% by 2030.
We aim to become a zero-waste-to-landfill business by 2026, and all our plastic packaging will contain 80% recycled content by 2025. That’s well beyond the UK Plastic Packaging Tax threshold of at least 30%.

BUILDING AGAINST THE TIDE: STRATEGIES FOR FLOOD-RESILIENT DESIGN
Here, Steve runs FC&A readers through his experience designing flood-resilient buildings and key considerations throughout the process, from regulatory requirements to water management.
Fl ooding poses a significant threat to many areas in the UK, with damage and management costing around £2.2bn 1 annually. For architects, engineers and developers, the challenge is clear: Create buildings that can withstand and rapidly recover from flooding, protect communities and reduce costs doing so. By understanding the innovative architectural techniques and strategic planning methods employed to design flood-resilient buildings, we can better prepare for future events and minimise their impact on lives and properties.
Flood risk assessment
T he journey to flood resilience begins with understanding the risks. In England and Wales 2 , over four million people and £200bn of property are at risk from flooding and coastal erosion.
D igital flood models, such as those from the Environment Agency, are revolutionising risk management here. These sophisticated tools enable precise predictions of potential flood levels, highlighting at-risk areas. They also offer better flood-resilience planning to inform the design of resilient buildings. Today’s models are highly accurate and quick, enabling engineers to simulate water flow through drainage systems and adjust designs to effectively prevent flooding.
O nce you understand the risks, flood management strategies must be tailored to the type of development. Residential areas, due to the higher risk to life, require stricter measures. In contrast, industrial developments might accept some flooding if material losses are manageable. This nuanced approach ensures each development type is appropriately safeguarded against flooding.
F irst line of defence
F lood barriers and waterproof materials can provide a line of defence if you can’t keep water away from buildings; however, their success hinges on good quality installation and periodic maintenance to ensure elements, like seals, remain intact. Human error and neglect can render these barriers ineffective, leading to breaches and water damage. Thus, while barriers are part of the solution, they should ideally be used alongside other preventive measures or as a last resort.
C hoosing the right materials is also crucial for flood-resilient construction. The key is to opt for hydrophobic materials that reduce the need for extensive drying and repairs after flooding, helping to limit the time people are kept out of damaged structures. For example, resin-based wood replacements, often used in decking or cladding, do not absorb water and are decay resistant.
STEVE MCSORLEY
Keeping it practical
T he real heart of flood-resilient architecture is practicality. While advanced materials and technologies are valuable, the primary goal is straightforward: Keep water away from buildings. This means that, if possible, avoid developing in flood-prone areas altogether. If building in an area at risk, elevating land or structures above expected flood levels, using tried-and-tested methods like stilts is a proven strategy to avoid water. This proactive approach shields buildings from floodwaters and minimises water displacement, preserving a floodplain’s natural function and protecting surrounding areas.
Water management
O n the flip side of the coin, you can also design an area to manage flooding better. Effective water management for flood resilience revolves around four key aspects. The first is the volume of water being discharged from a site. If you’re building a large factory on an open field where water initially runs off slowly, this will accelerate with a structure, effectively increasing downstream flooding.
Water quality is another consideration, as sustainable drainage systems (SuDS) can improve downstream water quality
by reducing sediment and contaminants from runoff. Thirdly and fourthly, designs must not adversely affect biodiversity and aesthetics. Legislation and guidance, such as the SuDS manual, illustrate approaches to managing these elements.
Techniques like underground attenuation tanks, ponds and swales can be deployed to manage surface water runoff and prevent increased downstream flooding. This is much more practical on greenfield sites, however, as they offer more design flexibility. Brownfield sites, with their existing structures and limited space, pose greater challenges. Here, more creative alternatives like permeable paving and green/blue roofs come into play. Permeable paving filters water and provides storage, while green roofs, which are storage mats covered in vegetation, store water and slow its discharge.
The power of collaboration W hatever technique is deployed, building flood resilience is a team effort where engineers, developers, architects and local authorities must work together closely. For instance, engineers must engage with lead local flood authorities (LLFAs) and the Environment Agency to ensure compliance with regional and national standards. Early collaboration
can ensure drainage solutions are seamlessly integrated into site designs, balancing functional needs and aesthetics with regulatory requirements. Creating flood-resilient architecture demands a comprehensive approach that combines legislative compliance, advanced modelling, practical design and collaboration among all stakeholders. By focusing on keeping water out and ensuring quick recovery if flooding does occur, we can better protect communities, reduce recovery costs and enhance the safety and resilience of buildings. This practical, strategic approach is essential as we face the rising flood risks posed by climate change, which threatens to increase damage from flooding by a fifth3 when compared to today. Together, we can build a safer, more secure future for everyone.

As the saying goes, actions speak louder than words and so it is a measure of the importance Vicaima sets in its ESG obligations that it has laid out the facts and figures of its path through sustainability.
M ost recently, Vicaima announced that sustainable production and consumption was one of its major areas of action, working actively to extend the lifecycle of its solutions, by optimising the entire value chain and minimising waste.
T he Vicaima Group’s approach to this issue has produced concrete and measurable results. In 2023, a total of 4139 tonnes of waste was generated, representing a 15% decrease compared to the previous year. From this volume, of which wood waste represents a significant part, 96% was valorised through reuse in new products, recycling or the production of thermal energy.
D uring all operations, the different waste circuits are continuously monitored and categorised, making it possible to optimise the separation and forwarding of waste for recovery via the various duly accredited waste partners or operators, with the aim of being reused and reintroduced into the value chain, thereby avoiding the final destination to be landfill.
In this context, priority is given to progressively include in Vicaima’s manufactured products or those that it integrates throughout the supply chain, renewable materials, highpercentage recycled materials or wood-based products made from fast-growing natural fibres, rather than virgin raw materials.

With a long and illustrious history, cast stone became a preferred building material in the 18th century when classically-inspired country houses were increasingly popular.
Often regarded as a superlative material, natural stone’s unrefined, organic composition, stability and appearance make it an established choice in the architectural industry. Yet sourcing and working with natural stone has its drawbacks, and architectural cast stone offers specifiers an easier-to-use, more cost-effective alternative.
Na tural stone has been excavated from the ground via quarrying. Today, the most common natural stones that are extracted are limestone, marble, granite, slate, sandstone and travertine. Cast stone, by contrast, is a special type of reconstructed stone produced using a blend of limestone, pigments, additives, sand and cement.
He re are some of the main benefits of specifying cast stone: Ap pearance: High-quality cast stone has the appearance of natural stone and is almost impossible to distinguish from its quarried equivalent
www.haddonstone.com
Ve rsatility: Because cast stone components are produced using moulds, almost any style and scale can be achieved
Co st: Like for like, in most cases, as a reconstituted material, cast stone is a far more competitively priced material than natural stone. The cost, therefore, not only decreases project risk but opens up a wider expanse of architectural possibilities.
Pe rformance: With a minimum cube compressive strength of 3 MPa, cast stone can significantly withstand load and, if specifying wet cast stone, reinforcement can be added to produce structural loadbearing units
Du rability: Cast stone weathers similarly to natural stone and has sound freeze/thaw resistance, so is easily able to withstand even the harshest of weather conditions. Also, there is no natural strata in cast stone which can be a weakness in natural stone.
BAUDERFLEX BITUMINOUS WATERPROOFING SYSTEM
SPECIFIED FOR EASTBOURNE DISTRICT GENERAL HOSPITAL
Eastbourne District General Hospital was originally constructed in 1977 and has undergone several major repairs throughout its lifespan. Recently, the ageing roof required significant attention, prompting the decision to embark on a refurbishment project.
Th e impetus for the refurbishment came from Eastbourne District General Hospital being granted funding by the Carbon and Energy Fund (CEF) through the Public Sector Decarbonisation Scheme (PSDS) for affordable, low-carbon energy-efficiency upgrades for the trust. Taking a whole building approach, the project used a wide range of energy upgrades to target carbon savings of 4129 tonnes.
Bauder addressed critical issues, particularly the original roof’s poor performance and the lack of insulation, with a specific focus on achieving the environmental goal of carbon reduction to meet the project requirements.
B auderflex bituminous waterproofing was specified for the refurbishment solution. In alignment with the project’s environmental objectives, the CEF-funded refurbishment targeted the roof’s insulation, which was
previously non-existent. The insulation was upgraded with 120mm BauderPIR FA-TE flatboard insulation across the roof, achieving 0.18 U-value. Working closely with Clarke Roofing and Veolia, a comprehensive package was developed, including core samples, survey reports, U-value calculations, carbon saving reports, specifications and solar PV designs to form a crucial part of Veolia’s bid to secure the project.
The completed project provides a 20-year guarantee for both product and workmanship. Throughout the process, project management and workmanship were closely monitored, with over 30 interim inspections and numerous site meetings.
T he roof system delivers significantly improved thermal efficiency for the building, thereby reducing heating bills and carbon emissions to achieve the project requirements of improving energy efficiency and reducing the hospital’s carbon footprint.
The successful project not only met the environmental goals set by the CEF, but also ensured there was minimal disruption to the hospital’s operations, showcasing the effectiveness of careful planning, adaptability and collaboration in complex refurbishment projects.

NEW LIFTS REVEALED AT ASTICUS BUILDING
The Asticus London building, a striking 10-storey landmark, has undergone a remarkable transformation.
Or iginally constructed in 2006, the office building features a stunning new reception, business lounge, landscaped terrace, breathtaking 360º panoramic views, luxurious end-of-trip facilities in the basement and the addition of four new Stannah passenger lifts, one of which can be used by emergency services in the event of a fire.
A rchitect firm Aukett Swanke envisioned a remarkable Cat A office refurbishment design, with a strong focus on sustainability, achieving BREEAM ‘Very Good’ accreditations. The building prioritises inclusivity, with the new lifts providing daily step-free access.
S tannah installed three passenger lifts, as a triplex, each accommodating 13 people, transporting visitors and staff from the ground floor all the way up to the new tenth floor, with one lift extending to the basement. Stannah installed the lifts using a scaffold-less method. These passenger lifts were specified at 1000kg capacity and operated at a speed of 1.6m per second, providing a quick and efficient ride for passengers.
S tannah also installed a fourth lift, which is for firefighting but can be used as a normal passenger lift. A firefighting lift is an essential safety asset in highrise buildings and has dedicated control
features to aid the fire and rescue service. Some of the key features included in the firefighting lift design are trap doors, ladders, an emergency intercom system and a separate power supply used by firefighters during rescue operations.
T his ensures the lift can operate efficiently even if the main building electrics are compromised. All the lifts adhere to the relevant performance and safety standards.
N ew modern lifts were required to accommodate the increased number of people working in the building due to the addition of a new storey. This resulted in the need for a fully-compliant and modern firefighting lift to meet the associated fire and safety specifications.
T here was an existing firefighting lift, although a survey by Stannah revealed concerns about compliance and operational issues. Before the new lifts could be installed, the four existing lifts had to be removed whilst minimising disturbance to the building occupants, ensuring safety and retaining step-free access at all times.
T his site was a live office environment, meaning it had existing tenants on some of the floors. As always for Stannah, safety was the first priority during the work, as well as managing dust
and noise levels. The Stannah team took great care in understanding the operational requirements and concerns of the building occupiers to ensure that disruption to their daily activities was kept to a minimum. This even involved site tours so they were fully involved in all aspects of the programme.
T he lift solution provided by Stannah at Asticus centred around accessibility, design and, for the fourth lift, fire safety. Stannah provided a tailored lift solution that not only fulfilled the design requirements but also aligned perfectly with the logistical needs of the construction process.
To ensure precision in meeting the design requirements, Stannah delivered black-painted glass car finishes, with careful attention to the equal spacing of grey vertical stripes, even where the back and side panels met.
A dditionally, two lifts were installed with counterweight safety gears, emphasising Stannah’s commitment to delivering a functional, secure and aesthetically-pleasing lift solution tailored to the specific needs of the project. The bespoke full-depth architraves, which were acid-etched with floor markings, added a decorative touch to the building’s design.

THE TRANSITION TO A MORE SUSTAINABLE FUTURE
The use of diesel fuel to power construction plant and machinery has been identified as one of the ‘hotspots’ in energy consumption and carbon emissions for many contractors across the UK. With businesses seeking to reduce operational carbon emissions, this creates an opportunity to achieve significant steps towards sustainable construction and net-zero targets, say Jason O’Brien, General Manager at United Powered Access (UPA), and Stuart Brown, Managing Director of CA Roofing Services.
Re search has been conducted into alternatives to diesel fuel, including portable solar power, hydrogen and Hydrogenated Vegetable Oil (HVO). The considerations include the performance of fully electric and hybrid machinery in varying weather and terrain, along with how contracting teams interact with them. The challenge with EV plant equipment is usually the practicality of accessing suitable electric power throughout the construction process when grid-supplied electricity is not available.
U nited Powered Access (UPA), one of the UK’s leading plant hire businesses for the construction sector, and CA Roofing Services, one of the UK’s largest metal roofing and cladding contractors, have collaborated on a sustainability business strategy, supporting their customers and clients on a critical and fundamental mission to reduce carbon emissions.

WHY 150MM CAVITIES ARE BECOMING THE NEW INDUSTRY NORM
Next year will see the introduction of the Future Homes Standard (FHS) and a 75% reduction in operational carbon for new homes, compared with 2013 standards.
Th e housing sector needs to adapt quickly and already we’re seeing signs of change. For example, a survey of housebuilders revealed that 150mm wall cavities are becoming the new industry norm, with 41% of participants already having made the switch for new homes and over a quarter considering it. Designing with wider cavities provides flexibility in choosing insulation materials that deliver the thermal performance new homes need.
For example, poorly-installed insulation may not achieve its specified thermal performance, and rigid board insulation can be particularly prone to this because it won’t sit flush against a cavity unless it is perfectly flat. It also requires precise cutting and taping, introducing further opportunities for human error. This can lead to air gaps and compromised thermal performance.
H ere, 150mm cavities offer a solution. They allow for the use of mineral wool insulation, such as Knauf Insulation’s DriTherm Cavity Slab 32, which is easier
to install correctly under real-world conditions. Mineral wool is a flexible material, so it adapts to minor imperfections in the substrate, fully filling the cavity. Its strands also ‘knit’ together, minimising gaps and maximising thermal performance.
D esigning with 150mm cavities addresses current and future requirements while maintaining design flexibility. Wider cavities help architects to deliver homes that meet the highest standards of performance.

MORE CHOICE, MORE PACE
GEZE UK is delighted to announce that several new products have been added to its range of pedestrian traffic control systems, PACE, to give even more choice when selecting solutions that offer safe and efficient control of pedestrians in and out of buildings. All products are supplied and installed in accordance with EN 17352:2022, the standard for powered turnstiles and speed lanes that was harmonised in August 2023.
New to the range are the SL 550 and SL 900 speed gates with stylish folding high gates and a reliable, robust design that guarantees effective protection of the building making them ideal for banks and offices.
T he popular SW 100 range has been extended to include two extra-wide options. The SW 100 Wide and SW 100 High Glass Wide both offer a passage of 1200mm, perfect for ease of carrying luggage and wheelchair access.
OX S, OX M and OX XL are a new series of aesthetically-pleasing turnstiles with ergonomic design and efficient control – ideal for high-traffic flow locations.
I n the full-height category, the HW G / NG with glass leaves and side panels perfectly combines modern aesthetics and functionality for even greater security with high visibility.
More cost effective than manual checks and providing round-the-clock control in buildings that are operational 24 hours a day, pedestrian access control is ideal for controlling access to any part of a building that requires it, as well as the main entrance.
T he PACE range can be tailored to the needs of any specification, compatible with many control devices – push button and card reader – available for single or bi-directional use and different lane widths.
GILBERTS UPS THE STANDARD IN SMOKE AND FIRE PROTECTION
With growing emphasis on managing the risk of smoke and fire within building safety, one of Britain’s leading air movement engineers, Gilberts, is leading the way to optimise control.
www.gilbertsblackpool.com
To address increasing demand and exceed criteria laid down in the latest Building Regulations, Gilberts is launching a new, fullytested range of insulated smoke and fire dampers. The insulated dampers complement Gilberts’ established Ductgard units for HVAC ductwork.
T he insulation element of the new dampers helps minimise the risk of heat transfer and thus the risk of fire spreading beyond the compartment. Its performance exceeds the two relevant layers of fire safety in buildings: Integrity of compartmentation and structural safety.
S pring and thermal fuse activated, the insulated dampers offer fire resistance of EI30, EI60, EI90 and EI120 for general ventilation systems with walls and partitions of various ratings. T hus, they deliver effective cut-off partitioning between the fire-engulfed zone and the remaining part of the building, helping maintain the building’s integrity.
T he range is fully tested and certified to EN 15650, EN 13501-3 and EN 1366-2.
T he introduction of the insulated dampers builds on Gilberts’ 60+ years’ heritage of bringing to market advanced technology that enhances the design, safety, energy efficiency and occupier comfort of non-domestic buildings.
A ll Gilberts’ products – standard lines and bespoke solutions – are designed and developed in accordance with the BS EN ISO 9001:2015 quality standard in the company’s state-of-theart 140,000ft 2 facility in Blackpool.
