Shown here is a competition visual for The Museum of the History of Polish Jews in Warsaw - but how will it look in reality? You can find out in our next issue. The competition-winning design, by Architects Lahdelma & Mahlamäki (working in conjunction with Kurylowic & Associates in Poland) aims to create a ‘lantern in the park’. The design features a layered facade design using pre-patinated copper in combination with glazing. The play of advanced LED lighting behind the decorated glass on the green corrugated copper will play a key role in this luminescence.

The magazine is distributed to architects and professionals in the building construction industry in Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Italy, Netherlands, Norway, Poland, Russia, Spain, Sweden, Ukraine and United Kingdom.

Copper Architecture Forum 32, April 2012

sion to a restored London warehouse (p 12–15) uses bronze cladding to define its thoroughly contemporary massing. In this case, an uncompromising form reflects the gabled profile of the original, creating a unified composition. A similar but lower key approach is taken with a London church extension (p 32–33). The relationship of new and old linked buildings is also explored with a new country house ‘orangery’ (p 8–11) in the Netherlands. This fresh take on an old typology is a heavily glazed pavilion with a curved, green pre-patinated copper roof which bonds it with the original house. A more literal stance is taken with Warsaw’s new water treatment plant (p 22–25) that refers strongly to the gabled forms and curved-head windows of its 19th century neighbours. Here, copper plays a more traditional role as a roofing material. And we consider the part played by copper in different forms – transparent and modulated – to regenerate uninspiring 20th century buildings (p 16–17 and p 30–31). We end as we began, with another example of a copper intervention reshaping the urban context of its older host – this time the former public baths in Thiene, Italy (p 36–38). Here, a redundant building has been given a new life as a unique youth centre defined by organic, curved copper shell additions. We hope you enjoy this journey around these inspirational projects, where copper acts as a catalyst for inventive architectural and urban regeneration.

COPPER ARChitECtuRE

This entire issue is dedicated to the ingenuity of architects in regenerating the environments that we live and work in. Preserving and adapting existing buildings and townscapes to suit new uses is sustainable, saving on resources and making the most of assets. But it also carries with it a challenge for designers in developing their particular interpretation of history and context for the 21st century. The diverse projects that we explore here demonstrate different approaches to this challenge and range from additions and interventions with existing structures, to new buildings interacting with the old to reshape urban areas. But one common strand runs through them all: the unique and numerous possibilities offered by copper and its alloys for architectural expression. Our cover story ably demonstrates this. Here, brass-clad forms worm their way amongst the urban fabric, defining new vistas and a fresh focus on Lund Cathedral. Initially bright and modern, the brass surfaces will soon darken and mellow, taking on a timeless feel. The same quality applies to the pre-oxidised copper interventions to an historic Italian villa (p 18–21), redirecting axes and circulation to suit the building’s new role as a hotel. Copper’s ageless and permanent nature is further reinforced by the brass elements added to a Spanish castle (p 34–35). Here, there is no pretence at literal reference but an abstract aesthetic totally in keeping with the massive stone remains. This approach has parallels with the use of copper to clearly express modern additions to a traditional Luxembourg village house (p 26–29). On a bigger scale, the new exten-

Internally, the dominant space is the entrance lobby, served both from the cathedral square and Kungsgatan. With its double height atrium, it is a convivial meeting place used for reception, exhibitions and refreshments, overlooked by offices on the upper floor. Here, the solidity of the plank shuttering embossed concrete walls contrasts with the openness created by fully glazed partitions. The expressive auditorium is designed as a unique space with

outer and inner sequential spaces and will be a gateway for visitors to the Cathedral and a forum for in-depth study and discussion. The new building has a simple but expressive design that interplays with the surrounding townscape through its angles and declivities. Brass was chosen for the new building’s external skin as a natural material that gives a rich, vibrant surface. As the material mellows with age, the building will gradually blend in with the townscape.”

In its new, bright state, the building is certainly asser-

tive and demands a response from visitors. But as the brass darkens naturally with age over the first few years, it will take on a more subtle, timeless quality. The forms and movement of the building across the site succeed in preserving important historic views while also creating new perspectives. More intimate and varied public spaces are also generated around and within the visitors’ centre. At its opening last year, Bishop Antje Jackelén aptly described the new building as “the Cathedral’s extended embrace”.

Copper Continuity Architects Braaksma & Roos’ interpretation of the country house Orangery uses copper to provide contextual continuity – but as a thoroughly modern material, as they discuss here. Commissioned by SAS Institute Inc., we developed a plan for their headquarters in The Netherlands. SAS (formerly known as “Statistical Analysis System”) is based in a grand, historic country house in Huizen. When the company approached us, the house had an extension wing that dated from the early 1960’s in decay. The essence of our design concept lay in replacing this extension with a contemporary interpretation of the Orangery – a traditional outbuilding associated with grand country houses. This was intended as a legible addition to the historical context of the original house, whilst at the same time setting itself apart as a thoroughly modern building.

A dialogue was developed between old and new. A dialogue was developed between old and new. The original house is mainly defined by white plaster with glass as the collateral material, whereas the new Orangery is effectively built of glass with secondary internal elements executed as white plastered boxes. The entire Orangery roof is covered in copper, just as the distinctive, original curved bays of the house. Pre-patinated copper perforated screens are used to form the main doors to the east elevation, adding to the Orangery’s air of transparency.

COPPER ARCHITECTURE FORUM 32/2012

Transparent Copper With the transparency of its glass and perforated copper facades and its physical separation, the Orangery stands apart from the main house and the surrounding landscape “washes” through its space. To further diffuse the transition from inside to out, the interior stone floor extends outside to follow the outline of the roof’s projection. A wooden deck extends around this stone floor, given more width on the South side to form a fine terrace.

The main function of the Orangery on the ground floor is to “Meet & Greet”, largely within the dining area. In addition, a separate interior and exterior Auditorium and a lecture room are also situated here. The first floor accommodates two open plan offices, as well as cellular offices, while secondary spaces are contained within the white boxes. Above these boxes, situated on the north side, the copper roof lifts up like a bonnet, to house the air exhaust.

A FUSION OF

NEW AND OLD This project showcases creation of a new life for old buildings with facilities to meet 21st century needs, whilst respecting and celebrating their integrity. A new bronze-clad extension is both a dramatic statement and a delicate intervention – the whole is a harmonious fusion of new and old. Located in the Abbey Road Riverside Conservation Area of the Roding Valley in east London, the locally listed Granary building had been derelict and unoccupied for some considerable time and was in urgent need of comprehensive restoration to bring it back into use. In 2009 planning permission was granted for a scheme designed by Schmidt Hammer Lassen (SHL) for a new Creative Industries Quarter centred on the former Granary and Malthouse buildings.

A Light Gentle Touch Pollard Thomas Edwards architects (PTEa) was subsequently appointed to develop the SHL scheme – the essence being to optimise the use of the space, both in the new and old buildings, whilst at the same time preserving the original character and historical references. Although substantial work was needed to repair and restore the original fabric, as far as possible the ethos of the conversion was sensitive restoration – a light and gentle touch. The refurbished Granary, with its new bronze-clad extension will form the new headquarters base for the developer and contractor Rooff, as well as occupation by other creative and commercial users. Rooff have introduced sustainable construction methods, to deliver the highest quality working environment at a viable cost. The plan form and shape of the new extension is respectful of the original building and takes its cue from its strong gabled form. The new materials, notably bronze panels, further complement the original. The entrance opens directly into a central vertical circulation hub between the two wings, which has been carefully inserted into the old building fabric – with modern materials, colour and lighting complementing the background historic fabric. This hub gives a new and dynamic heart to the building, fully accessible to the public who enter. The new accommodation is attached to the existing via the vertical circulation core and a high-level bridge link.

Catalyst for Regeneration The completion of the Granary and the construction of the stunning new bronze clad extension form part of the first phase of the longer term regeneration objectives for the Roding riverside frontage and is very much seen as an important catalyst for further regeneration in the area. It is being held up as a beacon of good design and conservation practices, delivered in one project, and won the ‘Commercial’ sector of the 2011 World Architecture News Awards.

INTERVIEW Chris Hodson discusses the design of the bronze cladding on this project with Andrew Stokes, project architect at Pollard Thomas Edwards architects. CH: How did you develop the design of the prismatic extension? AS: Initially, working with SHL, we used techniques such as solid and void relationship studies to explore form, fenestration and sun control.

Studies for the extension exploring solid and void relationships.

14 COPPER ARCHITECTURE FORUM 32/2012

CH: How did the selection of bronze cladding for the new extension come about? AS: The initial SHL proposal used Corten steel but this was changed to copper due to client concerns over weathering and waterproofing details. We then reviewed copper, bronze and brass and various other metal cladding materials but in the end bronze was chosen. The design intention was for a modern aesthetic and detailing to the extension, to contrast dynamically with the historic context, whilst at the same time acknowledging this history by using a traditional building material like bronze or copper.

CH: Did you also consider material changes over time? AS: The weathering characteristics were also key, as the roof – or inclined wall – is very visible and will weather differently to vertical surfaces. We were advised that in the short to medium term the bronze was likely to weather slightly more evenly. CH: What about sustainability and environmental considerations – were they important? AS: Yes, definitely. Like copper, bronze has sound and proven sustainable credentials in terms of its exceptional durability and lifespan, the fact that it is virtually maintenance free and that it can be completely recycled. CH: How was successful detailed design of the facades achieved? AS: We used envelope working models to explore different ways of expressing the metal cladding – for example, panel shape and size, and vertical, horizontal or inclined joints. The shape of the building called for a more 3 dimensional approach, as the roof is essentially an inclined wall, and these models allowed us to understand the interplay of key elements such as windows, rooflights and the main gutter with various metal panel configurations.

Cross section through new extension, hub and existing building.

The models enabled us to explore solutions for maintaining the integrity of the prismoidal shape by creating a similar appearance on all faces of the building, not only in terms of the cladding, but in the form, shape and detailing of the windows and the roof-lighting which we felt should be expressed as ‘windows in the roof ’ rather than traditional rooflights.

Like copper, bronze has sound and proven sustainable credentials in terms of its exceptional durability and lifespan.

CH: How do you feel about the completed bronze cladding? AS: We are very pleased with the final realisation. The bronze is weathering well, the edge, reveal and arris details are crisp and clean, and the horizontal format of the panels and staggered vertical joints integrate well with the random window location and sizing. The subtle undulations of the panels lighten and soften the ‘newness’ of the extension, which marries well with the patina of age we endeavoured to leave evident on the historic buildings. Careful consideration was given, in liaison with the cladding subcontractor, to all junctions of materials with the cladding and the detailing and setting-out of all joints, which has paid off in the final look of the building.

Timeless

COPPER In its inspirational rural setting at the foot of Italy’s Monferrato Hills, Rocca Civalieri was the summer sanctuary of Piedmontese nobles from the late Middle Ages. The villa and its associated buildings have now been restored, adapted and drawn together by a thoroughly contemporary, copper-clad intervention which fully respects the original building fabric, to create a convention centre, hotel and spa.

A timeless skin of pre-oxidised copper is used to express the new additions, starting as a ‘rusticated’ base to the original classical villa. The horizontally stratified dark copper then develops into a new spa building which defines and divides separate external areas either side. The overall composition aims to create “a place with clearly recognizable connotations – respecting the existing architectonic and landscape values.” As architect Stefania Masera explained: “The demands of a building complex accommodating various different functions but still presenting itself as unitary whole suggested the creation of new circulation routes on two levels leading into a new addition. This addition then defines a new, open, main entrance courtyard to the complex. It also establishes, in conjunction with existing buildings now converted to bedrooms and suites, a more intimate courtyard characterised by a central, light timber pergola structure. The copper additions draw together the diversity of buildings and their spatial organisation, creating a place with clearly recognizable connotations.”

COPPER ARCHITECTURE FORUM 32/2012

Alterations to the original fabric have been minimised and focused on the creation of flexible spaces to meet changing needs of the complex. On the ground floor, in addition to entrance, reception and bar, there are various communal and meeting rooms. The first floor houses a conference room with a small foyer and restaurant with kitchen and staff room, and hotel rooms and suites occupy the second floor.

Pure Water under

Copper Roofs Commissioned in 1876, the Filtry Waterworks was designed by British engineer William Lindley, who had previously gained recognition working with railways and, particularly, municipal infrastructure projects in numerous European cities. He designed the first underground sewers in continental Europe and, together with his sons, he designed systems for cities in Germany and elsewhere – including St. Petersburg, Budapest, Prague and Moscow – also turning his attention to urban planning. At Warsaw, he created a water purification system that continued to operate until the latest regeneration work. Here, he also collaborated with the architect Julian Herde with a complex of buildings generally faced with red ceramic tiles and decorative sandstone elements. Roofs were metal sheet on structural steel and windows steel-framed. A key aspect of Filtry’s success in its urban context is the green landscape covering about 70% of the site area. This unique and historic infrastructure complex is ‘protected’ locally and listed as a UNESCO World Heritage Site.

Upgrading Performance The well-loved landmark endured various changes after the 19th-century including additions in the 1970’s which took no account of the local environment and attached no importance to the original buildings’ scale and form. In the mid-1980s, restoration of the original buildings began under the current architect, Richard Sobolewski of Dorjon International, including replacement of the zinc-coated iron plate roofs with copper. Technical and performance requirements have driven the latest, recently completed new treatment building. Water quality has now been improved within modern parameters and in line with European Union standards, and the use of chlorine dioxide for water disinfection and treatment has also been substantially reduced.

he owners of this 19th century cottage in a small village north of Luxembourg decided that they would retire there. The house, as it was, had the charm of an old cottage but did not offer the required comfort for a main Photo: Paulo Lobo â&#x20AC;&#x201C; Luxedit

residence. The attached barn was being used as a garage and shed and the idea was to transform this huge empty volume into a new living room with a kitchen and to alter the existing cottage as little as possible. Various considerations influenced our design. The existing cottage has very small windows which give uninteresting views of neighbouring buildings, roofs and streets. The owners wanted views of their own property, gardens and the landscape. The existing stairs in the cottage were narrow, too steep and considered to be dangerous. It was decided that they should be replaced with wider and less steep staircases for safety and comfort.

COPPER ARCHITECTURE FORUM 32/2012

As the cottage will now be used by older people wishing to spend the rest of their lives there, it seemed obvious to design the layout in preparation for potential future mobility issues. As a result, it was necessary to locate a kitchen, living room, office, sanitary facilities and sleeping rooms all on the ground floor of the building, whilst the cottage. From an architectural point of view, we considered it necessary to clearly define the new parts of the building and the existing 19th century building. The owners wished to retain the authenticity of the existing cottage, which was probably built between 1805 and 1820.

Designers’ Response

retaining the possibility of a second, independent living space in

Working with the interior designer, our analysis of the owners’ proposal rapidly revealed that the barn was not big enough to accommodate the new living room and kitchen. Moreover, there were not enough windows on the facade to allow sufficient light into the living room and they did not offer the desired views of the landscape and the property. It was therefore obvious that an extension was necessary. In accordance with the wishes of the owners, the forms of the new volumes signal a contrast between our way of living now and the way we lived some 200 years ago. As a result, the old and the new are interrelated - yet provide a

contrasting effect. The transition from old to new does not operate on one precise borderline but rather by the effects of transparency and sightlines from old to new and vice versa. The new, very large plate glass windows open the perspectives up to the more set back

Externally, the intervention is conceived as a three dimensional box-like form, firmly integrated into the existing building fabric and reacting with existing facades – not just a new storey sat on top.

The designers, Architektenburo Ten Hove, commented:

“We deliberately chose copper for the mesh skin, where the colour of the material naturally changes over time and therefore indicates the age of the building.” Using a grid of equilateral triangles gives freedom from the constraints of linear structures and, with the copper mesh, diffuses the box surfaces externally. But internally, the mesh screen still allows clear views to the outside while providing solar shading, and inward opening windows allow ventilation and cleaning.

Copper for house on the rock Regeneration of this 19th century London church involved an extensive refurbishment programme to return the building to its former use. But it also involved a modern extension to provide a permanent home for the growing, 3,000 or so, congregation of the Nigerian-based‚ House on the Rock‘ church, as architects Paul Davis + Partners describe.

St George’s Church in the Tufnell Park Conservation Area was built in 1867 as a historical, circular building based on a 5th Century Greek Church and modelled on Shakespeare’s Globe Theatre. The building has had a colourful past. Saved from demolition in 1973, actor George Murcell turned the church into the St George’s Theatre. More recently it fell into the hands of squatters and it was only when they were finally evicted in 2006 that the project was able to commence. As well as its primary function as a church, the building is also used as a community 32 COPPER ARCHITECTURE FORUM 32/2012

centre, adult learning centre, crèche and a venue for other social events. To meet these demands, a new, copper-clad extension creates a contemporary architectural solution – contrasting with the church aesthetic, yet remaining subservient to the original building and making no attempt to emulate its style. This modern 2-storey extension links the existing church and the bell tower and provides flexible multi-purpose spaces to meet the needs of both church and community. The new intervention is separated from the original fabric of the church by a continuous band of glazing.

Matching the contemporary materiality of the new building with the stone and slate of the existing church provided a welcome opportunity to explore solutions for an ever-occurring challenge. Copper, with timber cladding and glass, provided the answer with a naturally changing surface and an air of permanence. The designers endeavoured to minimise energy demand by considering the embodied energy of materials and using recycled materials wherever possible.

Castle entrance approached via the straight staircase bridge with curved brass handrail.

A gradual regeneration is taking place to the ancient Ribadavia Castle in the Ourense area of north-west Spain, heralded by new brass elements transforming the entrances to the castle. Architect Miguel Angel Calvo Salve describes his approach to these interventions, which add an ageless simplicity and sense of permanence.

URBAN SHELL Architect Luisa Fontana explains how a shell-like copper and glass intervention regenerates a disused public bath house and reorientates the building to define a new urban square.

The original, early 20th century building had been unused for over 40 years and its previously hidden, undistinguished rear façade was exposed by the creation of a new public square in the 1980s. The restoration and expansion of the building provided an opportunity to redefine a new urban role. The European funded project is for a new Centre for Cultural Activities for Youth and is unique in Italy. It provides a link between the University and the World of Employment, creating an international focus to serve the local community.

A Bold Approach The regeneration – carried out in conjunction with engineers Arup (structure and energy strategies) and Manens (installation) – reflects a bold architectural and urban planning approach. It involves restoration of the original building and addition of a new volume, in the form of “shell” made of steel, copper and glass. The profile of the shell develops a close relationship with its urban context. It is ‘closed’ next to the old buildings, form-

Energy Independent The building is also an example of smart design and energy self-sufficiency, to minimise energy consumption and carbon emissions. Dynamic thermal modelling software, developed for the Arup building energy simulation, enabled solutions to be optimized and energy saving benefits quantified. The project has achieved an â&#x20AC;&#x2DC;Aâ&#x20AC;&#x2122; certification in the Eco Domus energy class with a system developed by VI. Energy. The result is an integrated organism, energy independent from the network, where climate and environment interact. Various renewable techniques are incorporated including geothermal energy, the pre-heating of primary air through an underground maze and self-generation of electricity using biodiesel. The design optimizes natural lighting and ventilation, while the building materials provide a high performance, thermal inertia envelope.
