COPPER COMBINATIONS As usual, we showcase a range of inspirational projects from around Europe and beyond. But what stands out in this issue is the diversity of approaches to materiality in design, combining copper with other high-quality materials.

Our first project is a residential building (pages 4-9) in a prominent riverside setting, clad in a golden copper alloy intended to contrast and interact with its sharp, reflective glass neighbour. Also contrasting with its surroundings is a prismatic copper pavilion (pages 10-11), bringing back to life the unloved central court of a suburban office building.

Next, a modern take on traditional house forms (pages 12-15) combines pre-oxidised copper with complementary coloured brickwork and minimalised detailing to create a unified mass. With another clever combination of materials – copper, brass and three types of brickwork – a city-centre residential project (pages 16-19) is conceived as a visually striking stack of blocks, maximising use of rooftops by residents. Another rich material combination, this time in Australia, defines a community centre (pages 20-23) and includes curved perforated brass, adding to its post-modern feel.

Sustainable and traditional materials, combined on a major scale, also characterise a Belgian city centre regeneration (pages 24-27). Here, a golden alloy of copper is applied in various forms including embossed, expanded and louvred areas. A contrasting approach is taken with large panels of brass, used as dramatic ‘picture frames’ around views into practice rooms and key areas of a music school (pages 2831).

For a renowned luxury spa in an outstanding natural location (pages 32-35), only the best materials will do. Here, carefully detailed brass panelling combines with rock and concrete as the building grows organically from the mountainside. Finally, we return to urban regeneration, this time in Moscow with examples of residential buildings clad with pre-patinated and pre-oxidised copper, alongside stone and brick (pages 36-39).

We hope you enjoy this issue.

ELECTRIFYING COPPER

4 COPPER ARCHITECTURE FORUM 45/2018

For London’s commuters, travelling on the Victorian railway viaducts running along the south bank of the River Thames creates a moving stage set, revealing exciting perspectives of the urban fabric. The latest addition to this scene, Faraday House, is a golden bolt of energy announcing the regeneration of the iconic Battersea Power Station, as its architects dRMM explain.

Faraday House is a residential building forming part of the first exciting chapter in the regeneration of Battersea Power Station. Sitting on the banks of the River Thames and adjacent to Battersea Park, the building occupies a prime site at the junction of the north-south rail line into Victoria Station and the Thames – and its design responds to this unique setting.

It forms the western edge of the overall masterplan, closing the courtyard formed by the adjacent glass building designed

by SimpsonHaugh and Partners, and which provides a contrasting backdrop with dramatic reflections.

STRONG CONTEXTUAL RESPONSE

Photo © Alex de Rijke

Our collaboration with SimpsonHaugh and Partners is the result of a competition process demonstrating that two contrasting buildings can be a strong response to the diverse context of the Power Station to the east and the railway to the west. Both buildings occupy a unifying podium providing access, service and a public face with retail, offices, restaurants, gym and pool, plus a secluded green courtyard above.

Faraday House’s organisational principle is inspired by Dutch architect Tejo Remy’s ‘You can’t lay down your memory’ set of drawers and the simple joy of stacking matchboxes. The arrangement of apartments, staggered in plan and section, follows the gentle curve of the railway. The geometry of copper-clad boxes is best experienced from a slow-moving train into Victoria Station – first, unordered like a rock face but then gradually revealing the rational, glazed facades of the apartments viewed side-on.

SITE PLAN

TYPICAL FLOOR PLAN The 113 apartments are arranged in clusters of three, around five cores, on eight floors. Staircases and lifts are pushed to the façade to give natural light, views and orientation to the residents. The design of the cores maximises efficiency and allows dual aspect apartments to the sides with a smaller apartment occupying the space between. Long views across the railway and the Thames contrast with the intimacy of the courtyard. Each apartment is designed with full-width balconies forming the geometrical expression of the building.

WEST ELEVATION - RAILWAY SIDE

SINGLE MATERIAL A single material cladding all external facades emphasises the power of the complex geometry. The golden copper alloy ages gracefully without losing its radiance. It is a natural material and, like the brick of the Power Station, it will change over time. The entire building, including recesses and soffits, was set out so the standing seam copper alloy enwraps the volumes, but without complicated detailing and visual distractions. Its trays were hand-formed on site from large coils and contrast with the sharp glass of the neighbouring building.

The manual process and natural material give Faraday House a soft appearance while its shining copper alloy finished forms are a fitting reference to the ‘Faraday shield’ of scientist Michael Faraday, after whom the building was named and, without whose discoveries in the 1830s, power stations like Battersea could not have been created and operated.

ENLIVENING COPPER As part of an office redevelopment and renovation project, a new copper intervention brings life to the previously unloved and inaccessible courtyard at the heart of this building in a Paris suburb on the River Seine. A lively place to meet and accessible to all, the pavilion houses a cafe and connects the lobby and circulation areas with the green spaces of the courtyard.

This bright copper prism was developed as a defining landmark to be seen from all sides and above

Photo: Cleaveland

This bright copper prism was developed to be seen from all sides and above: from the first entry into the main hall and from other accesses; but also from different levels of the offices. As used here, natural copper in different thicknesses can be provided with a time-tested, transparent, 2-layer coating to retain its bright beauty for longer.

Each detail has been designed and integrated to give the illusion of a massive block of copper, partly hollowed out to create a new space.

COMPLEMENTARY CONTEMPORARY

12 COPPER ARCHITECTURE FORUM 45/2018

This modern take on traditional house forms uses copper and brick to complement its more conventional neighbours in a riverside setting near Utrecht in the Netherlands. EVA architecten explain their approach.

The dyke house is situated overlooking the river Hollandse IJssel. The riverside elevation has been kept transparent to maximise the view, while the dyke side has a more modest, closed character to guarantee privacy. The house refers to the neighbouring houses in the original ribbon development in terms of form but has a contemporary character with minimal expressed details and rich materials. The copper roof and bricks have been chosen in the same shade of reddish-brown to make the whole appear as one volume.

SECTIONS

ORGANISING CORE The interior was designed in cooperation with NEST architects. A wooden core organises the internal spaces and comprises the staircases, storerooms and other facilities.

Consequently, the rest of the plan can freely be utilized. On the upper floor, all bedrooms overlook the river, while the support areas are arranged on the dyke side. Rooflights have been introduced for daylight in the spaces on this side. The rest of the roof can therefore remain clear and empty.

PLANS

The building’s design and orientation participate in its energy management. The open north side lets light enter but not the sun, while the more closed south side limits heat build-up.

Supplemented with extra insulated walls, a heat pump and solar panels, this makes for a very sustainable home.

AWARD WINNING PROJECT

MATERIAL DIVERSITY Architects Kjellander Sjöberg describe how urban blocks defined by materiality – copper, brass and three types of brickwork – generate a unique identity for this new residential infill in central Stockholm, while firmly connecting with the site’s local character.

Etaget is located on Western Kungsholmen, an area originally comprising offices and light industry, but developing over recent years into a diverse neighbourhood, with the emergence of complementary businesses and new housing.

The project aims to nurture the existing environment with a building that accentuates and develops its urban structure further. Commerce and inviting activities add an expressive urban character to the streetscape, making a city within the city.

Computer generated image illustrating massing and materiality

The architectural expression of Etaget refers to a traditional order found in the inner city of Stockholm: an open base with commercial spaces, a main body with housing and a top with set-back penthouses. The building’s configuration responds to the various heights of the site and its surrounding buildings. The design is based on a series of stacked cubes, displaced vertically. This creates a distinctive overall silhouette, adding depth and appearing visually striking both from a distance and from the adjoining streetscape.

RICH MIX OF MATERIALS

GREEN ROOF TERRACES

A rich mix of materials offers lightness and variety, with three types of brickwork, brass and pre-oxidised copper sheets – each defining a block – and niched terraces clad in timber.

We selected the brass and copper cladding to contrast with and complement the three brick types. But the metals also reveal something of the location’s history as an industrial manufacturing area. In fact, the original building on the site had a corrugated metal facade.

The 103 apartments are designed in a bright ‘loft’ style, offering varying sizes. The project focuses on green space and socio-ecological resilience. Given the dense innercity location, every available space is optimised to provide recreation and positive experiences for the residents. The green roof terraces are a new addition, containing both communal and private spaces for time outdoors, plant cultivation and socialising.

We also used copper or brass cladding and detailing to resolve all kinds of geometric and technical issues with this complex building. These included rainwater handling and covering junctions between prefabricated elements, as well as for railings, skirtings and other details.

Etaget has received a number of awards including 1st prize in the ‘Design S – Swedish Design Awards’ 2018.

SIX STAR BRASS Gently curving, perforated brass solar screens help to define the character of a key community building in Melbourne, Australia, and also to enhance its sustainability – recognised by a 6-Star highest ‘Greenstar’ rating. Architects GroupGSA tell us more.

The North Fitzroy Library and Community Hub is a threestorey building incorporating a library, Maternal Child Health Facility and a variety of community focused facilities. These include a new home for the City of Yarra’s International House, a cross-generational meeting place for people of different cultures and ethnicities. The design’s flexibility is manifested by distillation of cellular supporting spaces to the south and open flexible spaces to the north.

COMMUNITY FACILITIES

The first floor is divided between maternal and child health facilities, including two playgroup rooms and library. The second floor is focused on community facilities with large divisible spaces, commercial kitchen and shared community office. A rooftop garden, part-shielded by transparent brass screens, connects the northern portion of the second and first floors via a cascading design of planters and informal seating. This garden serves as an extension of both community and library spaces by providing a protected external garden space for interaction and study.

The tapered site presents long facades to the east and west whilst leaving little room for controlled solar access via northern exposure. The design concept overcomes that restriction by introducing a northern facade that is sequentially stepped along the West Axis, allowing controlled northern light to flood the building whilst shielding it from the western and eastern sun.

PERFORATED BRASS SCREENS The eastern façade allows glimpses into the building – particularly at night – with views out to the public urban space. Much of the glazing is shielded by the curved, vertical screens of perforated brass, each one offset against the next. The pattern formed by the perforations, executed by the fabricator, is based on the dappled light patterns from the trees in the adjacent Edinburgh Gardens and is a reference to these trees, and another gesture of bringing elements of the natural environment into the built form. This theme continues internally with perforated brass applied to internal features such as the reception desk.

Rive Gauche transforms the lower city into a dynamic and attractive district. With its programme of retail plus hotel, youth hostel, housing, offices and car parking, it completes and fosters the mix of urban functions, breathes life into preexisting activities and offers new employment opportunities.

Rive Gauche is not just about a building, but about creating a part of the city with the rebirth of a public square. It reconnects two districts, revitalises the city centre, creates a ‘landmark’ and interacts with the city.

TRADITIONAL SUSTAINABLE MATERIALS The building is an audacious monolith, lightened by extensive glazing and opened onto the city by multiple entrances and passages. The crushing effect of the existing 26-storey office tower is tempered by the new building at its foot. The facade overlooking the Place Verte is elaborated as a spectacular window on the city. By day and night, it fosters interaction between commercial and public spaces.

The architecture gives expression to the building’s public and commercial functions in the city. The architectural vocabulary plays with volumes, transparency and diversity, and intrigues by contrasting strong and light, monolithic and porous.

Traditional and sustainable materials are reinterpreted in a contemporary way. The lightness and richness of the golden copper alloy – expressed in both transparent, expanded metal screens and solid panels with surface relief – contrast with the massive grey bricks. By using the same bricks and granite pavement, a sense of continuity is created between street and covered promenade.

Created from large panels of brass, these ‘picture frames’ with mitred corners are intentionally two-dimensional in character, presenting minimal, pristine edges

ABSTRACT DESIGN

SILENT PERFORMANCE

The building’s pivotal location within the town is elevated by its sculptural abstract design and it is set to play a key role in the future development of the local community. Its layout is purely rational with the library at street level, acoustically separated from the music school above by a vestibule and staircase. The library is open visually to the main road and a sheltered wooden deck with fruit-trees and a playground.

Essentially, the building is constructed of cast concrete – exposed and beautifully finished throughout the interior where it is complemented by natural oak boarding.

The music school occupying the upper three levels is a cellular layout of practice and performance rooms, each with substantial, uninterrupted glazing. The design’s composition of interlocking, cantilevered brick boxes is relieved by massive sculptural frames defining the glazed areas. Created from large panels of brass, these ‘picture frames’ with mitred corners are intentionally two-dimensional in character, presenting minimalised, pristine edges. The street frontage displays a grid of brass-framed glazed squares with views into each practice room – an animated, silent performance in itself.

THE HEIGHT OF OPULENCE For a renowned luxury spa enjoying a mountaintop location overlooking Lake Lucerne, only the best natural materials will do, as architects plus4930 explain.

Redesign and remodelling of the legendary 1980s Bürgenstock Spa formed part of the revival of the entire Bürgenstock lakeside resort. The new Spa building grows organically out of the landscape, a polished artificial rock body, inserted and interlocking with the natural rock formations. The new facility maximises views of the surrounding mountains as an integral part of the overall sensory experience of bathing.

Through carefully planned cuts through the building mass, glances from the spa open up to the mountain and lake panoramas are created. The cuts for the rock terrace, with the hot springs in the east and the panoramic terrace in the south, lead the natural rock and mountain landscape into the interior of the complex. The interplay of a modern bathing and sauna world with the surrounding nature can be directly experienced on three sides.

BRASS CASSETTES The special charm of the old building is retained with features such as its fireplace, restaurant, pool house and kidney shaped pool. Old and new are connected by their materiality, sharing local alpine materials, although expressed by their differing architectures. The new building retains the character of a stone pedestal with a façade of exposed concrete emphasising the horizontal. On top, it is clad in vertically arranged brass cassettes creating a flat surface, interspersed with generous glazing. Over time, the brass will weather naturally to complement the brown copper façades of the original building.

it is only thanks to copper that the buildings’ appearance will continue to transform, adding one more variable to architectural composition – time.

“

Regeneration of an old industrial area close to Moscow city centre is characterised by its restrained palette of materials, including copper, applied by several architectural teams, each with its own individual interpretation of the common design code. Sergey Skuratov Architects discuss this thoroughly developed architectural and urban concept.

‘Sadovye Kvartaly’, the new Garden Quarters area covering some 14 hectares, enjoys an abundance of greenery and a strong industrial architecture heritage. One preserved historic building was taken as the basis for an approach to materiality across the development. It combined lightcoloured stone and traditional red brick with copper roofing and other details. These three contextual materials were chosen for the facades of the new residential buildings – ranging from 4 to 16 floors – forming several quads around a central pond with recreation area.

Combinations of the three main materials provide a wide range of visual possibilities, generating a fully-fledged urban ensemble. Buildings with facades of the same materials form successive chains or diagonal pairs, which create a compositional unity for the whole complex. And copper plays a key role in this symphony. On our projects, two forms of copper were used: brown pre-oxidised on Quarter 3 and blue/ green pre-patinated on Quarter 4.

CONTINUING CHANGE These living copper facades will continue to develop for many years. Copper’s ability to advance in age beautifully is one of its most important properties for architecture. Stone and brick will not change, and it is only thanks to copper that the buildings’ appearance will continue to transform, adding one more variable to architectural composition – time. And an unexpected duet of copper and the trees between buildings is also in play, gradually altering the scale and character of the architectural ensemble towards real ‘Garden Quarters’.
