The full diversity of galvanized steel is again featured within our winter edition of HDG magazine.

Amongst our many enticing articles, three in particular, raise important design concepts for the future.

Green House – takes inspiration from the natural history and lush character of its site to develop a modern energy-efficient domestic property. It encompasses a green façade of galvanized steel and sliding polycarbonate screens. The facade is planted with bamboo, which will softly filter the daylight whilst maintaining privacy and provide solar shading on hot summer days. The concept of materials and structures that could be left 'as is' was an important element of material choice.

Kittiwake Nesting Tower – It’s surprising that, at face value, such a simple design solution can have very important consequences for us all. This rather inventive – modular, movable, and adaptable tower design allows windfarms around our coast to obtain planning permission. It provides nesting structures for kittiwakes, that help the birds increase their fledging success rates, this is now legally required to compensate for any impact our wind farms may have on seabird populations.

Stables Yard – If we do need to build within a floodplain, Stables Yard is the way to go. A network of galvanized steel helps with securing ground conditions and the avoidance of losing a large area of land for rainwater soakaway. In addition, it provides a 80 year lifespan to the steel.

Effortless Elegance

Green House, London

The Green House design takes inspiration from the natural history and lush character of its site, presenting a modern and energy-efficient reinterpretation of a domestic-scale greenhouse. It serves as a family home that blurs the distinctions between indoor and outdoor spaces, initiating a vibrant transformation of a previously neglected area.

Situated within Tottenham's Clyde Circus Conservation Area, the current site, which was once home to orchards, greenhouses, and market gardens, now resides between two-storey brick houses constructed in the 2000s. The redesign of this location provided an opportunity for a photographer, a teacher, and their two young children, to connect with the site's history.

With a limited budget of under £3,000 per m2, it was aimed to create a five-bedroom home that maximized living space and provided a sense of height and access to nature. The chosen 'block' form of the house not only proved to be constructionally efficient but also supported the house's fossil-fuel-free design. It utilizes an air-source heat pump for heating and incorporates solar panels on the roof to fulfill electricity needs.

The Tottenham Riad, a central, top-lit, riad-style atrium, serves as the connective element for all living spaces, both upstairs and downstairs. This feature brings natural light into the heart of the house, a solution where side-facing windows would have been impractical due to the proximity of neighbouring properties. The atrium also aids in cooling the house through passive stack ventilation on hot days.

The design seamlessly integrates living spaces with the surrounding landscape, ensuring that every area within the house enjoys views of the sky or greenery. Double-aspect views extend to front and rear gardens, as well as the surrounding woodland and trees, fostering a sense of openness that links the interior with the exterior. The curtains, enveloping the entire atrium, not only create an impressive double-height dining hall but also contribute to acoustic absorption within the internal spaces.

For the south-facing green façade, a galvanized steel support frame was employed. Adorned with bamboo and featuring sliding polycarbonate-clad screens reminiscent of the site's historical greenhouses, this façade softly filters daylight, maintains privacy, and provides solar shading on warm summer days. The sliding screens, hung on substantial agricultural galvanized sliding door tracks, empower the occupants to manage views both in and out. Galvanized steel was selected for the façade framing primarily due to its durability and resistance to corrosion. This was particularly important due to the irrigation installed for the planting.

Adaptive Aviary

Kittiwake Nesting Tower, Gateshead

New offshore windfarms are now legally required to compensate for any impact their turbines may have on seabird populations. Nesting structures for kittiwakes, that help the birds increase their fledging success rates, are being built around our coast. ‘Kittiwakery’ was installed on the River Tyne, Gateshead in February 2023, as part of the 3GW Dogger Bank South offshore wind project.

FLI Structures in partnership with ecologists from Shoney Wind Ltd and kittiwake study programmes, have developed a flexible and modular galvanized steel design that delivers better performance than existing sites. Building these kittiwake nesting structures is in itself, not enough. They must work. Then, for the windfarms to retain their consent to output power, they must carry on working. Unfortunately, previously limited understanding of the bird’s needs and the microclimates around their nests; coupled with the inflexibility of these building’s designs meant that until now, they have typically failed.

The modular and adaptable nature of an open, bolted, galvanized steel structure, delivers the ability to refine or radically alter the tower to ensure both the initial and ongoing performance needed to fulfil the planning consent requirements of the offshore windfarms. The use of galvanized steel screw piles and a bolted, galvanized steel structure, means that when required, entire towers can be disassembled, unscrewed from the ground and moved to new sites.

The tower's flexibility allows for ongoing adjustments, ensuring optimal breeding success and addressing changes in environmental conditions. By enabling alterations to the layout of nest ledges, addition of nesting cabins, and even the relocation of an entire tower, the structure remains responsive to evolving requirements. This adaptability is pivotal in securing wind farm planning consent, allowing the structures to endure and perform over the long term.

Galvanized steel is central to the tower’s success, not just for its practical and economic advantages but by enabling the key features that deliver the tower’s sustainability credentials:

• The modular and adaptable nature of an open, bolted structure to ensure both the initial and ongoing performance needed to fulfil the planning consent requirements of the offshore windfarms.

• Galvanized steel screw pile and grillage foundations are 100% reusable and recyclable. Limited excavation, no soil cart away and lighter plant required.

• Galvanizing delivers a major advantage over painted surfaces in these situations, with no joints stuck together or bolts full of paint.

• The kittiwake tower unlocks offshore wind consent impediments to help increase the share of renewable energy in the global energy mix and improve affordability.

Unlike previous structures hindered by limited understanding of avian requirements and inflexible designs, 'Kittiwakery' ensures sustained functionality amid changing landscapes. Instead, they stand as resilient and enduring contributors to the delicate balance between sustainable energy production and environmental conservation.

Pioneering the Future

Driving Test Facility, Germany

In a former military shooting range, a unique project unfolded to create a state-of-the-art testing facility for autonomous driving technologies. The facility required a creative structural approach to navigate zoning regulations, height limits, and fire safety standards. This notable achievement highlights how clever engineering solutions can overcome complex challenges.

In order to facilitate planning constraints that included a maximum height of 8 m, a smart engineering solution emerged. The project called for a column-free layout for the testing track, presenting a distinctive challenge. To address this, a light truss type design was developed which not only met height restrictions but also established an unimpeded testing environment.

With exposure to the elements and an uncertain future enclosure, corrosion protection became crucial. Hot dip galvanizing was selected as the method of protection after careful evaluation. This process not only provided excellent corrosion resistance but also streamlined construction resulting in a win for forward-thinking engineering in the face of uncertainty.

Balancing innovative design with cost considerations was essential, especially in selecting structural materials. A thorough analysis was conducted to find the right balance. The result: an optimised galvanized steel frame design. This approach met structural demands while also proving to be a financially prudent solution.

This project showcases how efficient and effective engineering can overcome complex challenges. A cost-effective and robust solution was achieved even within the confines of stringent regulatory constraints.

Revitalizing Spaces

Garage

Transformation, Germany

In 2023, the conversion of a garage into office space was successfully completed in the picturesque Breitbrunn am Ammersee. The project came to fruition amidst the global pandemic, where the dynamics of work shifted towards the integration of home offices within residential spaces. This transformation, persisting even in a post-pandemic era, embodies a shift in our approach to the contemporary work environment.

To harmonize the realms of living and working, the workspace found its new home within an existing double garage. This adaptation not only optimises existing space but also avoids the need for additional land use and construction.
