Main objectives of the project

As the recipient of the 2019 EU Mies van der Rohe Award, this project involved the refurbishment of three social housing buildings comprising 530 units in Bordeaux, France. Originally constructed in the early 1960s, the need for renovation arose after the possibility of demolition was dismissed. Remarkably, the transformation of these dwellings occurred while residents continued to occupy them. A key aspect of the renovation involved extending the existing space by adding a winter gardens and balconies accessible from every room, akin to a traditional house layout. This expansion not only broadened the usable space and mobility within the buildings but also redefined the quality of housing offered while improving the energy efficiency of the building envelope. This project serves as a compelling example of forward-thinking, responsible housing solutions for the future.

Description

This project presents a bold approach to challenging the existing European housing stock from the post-war era, achieving remarkable results with minimal resources. Rather than opting for demolition, which consumes significant energy, the client recognized and endorsed the benefits of transforming three existing buildings. Through this initiative, social housing, often criticized for its built heritage, serves as a model for relevant and cost-effective transformation, turning perceived deficiencies into generous, inviting, and efficient dwellings that redefine typologies, living conditions, comfort, and aesthetics, thereby enhancing the urban residential landscape.

The transformation imbues all dwellings with new spatial qualities and living standards by meticulously assessing existing strengths to preserve and identifying areas for enhancement. The addition of expansive winter gardens and balconies to each apartment offers increased space, natural light, usability, and panoramic views. Small existing windows are replaced with large glazed sliding doors opening onto the winter gardens. Technical upgrades include renovations to bathrooms, electrical systems, and the replacement of two former elevators with a larger, more efficient one in each staircase. New access halls and improved front gardens enhance the overall environment. Throughout the construction process, all families remained in their dwellings, with no rent increase post-transformation.

The project, executed with inhabitants in residence, avoids structural interventions such as changes to stairs or floors, opting instead for additions and extensions designed for full utilization. Internally, only facility refurbishments and finishings were undertaken. The 3.80-meter extensions expand usable space and mobility, seamlessly connecting rooms to the winter gardens, akin to private semi-outdoor spaces found in houses. The energy efficiency of the building envelope is significantly enhanced by these winter gardens, serving as passive solar collectors. Focusing on economy, the budget prioritizes extensions, crucial for substantial and sustainable improvements in dwelling quality, while overall transformation costs remain within budget parameters, aligning with typical expenses for basic facade renovations, insulation, and facilities.

Construction materials and methods were selected to optimize efficiency and minimize disruption. Concrete was exclusively used for foundations, with concrete window sills removed to facilitate floor-to-ceiling openings for double-glazed sliding doors. Thermal curtains enhance interior insulation. Lightweight facades composed of transparent, corrugated polycarbonate panels and aluminum-framed glass, equipped with reflective solar curtains, provide exterior insulation. Glazed handrails line the balconies.

To expedite construction, prefabricated modules were employed, erected like scaffolding in front of the buildings. Precast slabs and columns were transported to the site and assembled into a freestanding structure using a crane. Efficient planning and scheduling allowed for a swift transformation, completing each apartment within 12-16 days: half a day for laying concrete slabs, two days for adapting the old facade, two days for installing the new facade, and 8-12 days for interior renovations.

Description

Beyond its primary function of providing housing, Circle House serves as a showcase for innovative approaches to circular architecture and construction, with the overarching objective of ensuring that 90% of its materials can be reused without any loss of value, thereby advancing sustainability within the industry. The project's buildings are designed to be dismantlable, allowing their structural components to be reused with minimal loss of value. Circle House comprises a variety of building systems that can be assembled, disassembled, and reassembled into other structures while retaining their economic and aesthetic value. It encompasses three typologies: a mix of two- and three-storey terraced houses and 5-storey tower blocks, including approximately 100 m2 of communal facilities. The building density on site ranges from 65% to 80%.

The project is focused on addressing the challenges associated with circular construction, including the renewal of traditional business models and the development of legislation that supports recycling. As a result, Circle House examines value chains, business models, business cases, and regulatory frameworks. The project disseminates its findings and achievements through extensive discussions about circular construction across the industry.

Funding for the project was provided by the Danish Environmental Protection Agency and the philanthropic association Realdania. Additionally, over 30 enterprises from the Danish construction sector, spanning the entire value chain, are involved in the project. The architectural design of the building was conceived by a Collaboration Studio consisting of 3XN/GXN, Lendager Group, and Vandkunsten Architects.

Main objectives of the project

Goldsmith Street in Norwich exemplifies a rare phenomenon in the UK: rows of terraced houses constructed directly by the local council, leased with stable tenures at affordable social rents. This collection of 105 homes stands out as an epitome of top-notch architecture, showcasing the utmost environmental and social consciousness. It holds the distinction of being the largest Passivhaus project in the UK.

Description

Goldsmith Street, an innovative development consisting of approximately 100 homes, was constructed by Norwich City Council, bypassing profit-driven developers. These homes epitomize true social housing, leased directly from the council with secure tenancies at fixed rates. Notably, they stand as some of the most energy-efficient residences ever erected in the UK, meeting the rigorous Passivhaus standards from Germany, resulting in a remarkable 70% reduction in fuel expenses for tenants.

Initially, the council had intended to sell the site to a local housing provider, but the plans were thwarted by the financial crisis. In 2012, the city made the bold decision to undertake the development itself, despite not having built homes for decades. Facing challenges, including the loss of around 500 council homes in recent years due to policies transferring public assets into private hands, Norwich navigated financial constraints. Current regulations allow councils to use only 30% of receipts from council home sales through the contentious right-to-buy policy to cover new home costs within a tight three-year timeframe. Nevertheless, Norwich found a solution, employing a combination of borrowing, funds from its housing revenue account, some right-to-buy receipts, and council reserves to proceed with the development independently, without a housing association or development partner.

London-based architects Mikhail Riches and Cathy Hawley won the competition for the site in 2008. Their proposal, distinguishing itself by advocating for streets over blocks of apartment buildings, was inspired by the Golden Triangle buildings, a coveted neighborhood characterized by Victorian terraced houses. This choice demonstrated a lesson in density, challenging planning norms by showcasing the possibility of maintaining humane scaling while accommodating more homes.

Extensive attention to detail is evident throughout the development, from the intricate brick balconies to the cleverly designed interlocking staircases in the three-story flats, ensuring each residence has its own street-facing entrance. Back gardens overlook planted alleys featuring communal tables and benches, while parking is relegated to the site's perimeter, prioritizing pedestrian-friendly streets.

In 2019, the buildings were awarded the prestigious RIBA Stirling Prize. Norwich continues to advocate for innovative approaches to social housing, addressing financial and social constraints to further its endeavors in this regard.

Main objectives of the project

The Housing Cooperative Berliner Bau- und Wohnungsgenossenschaft von 1892 eG (referred to as 1892) embarked on an experimental and forward-thinking revitalization of a housing complex dating back to the 1970s. This renovation was guided by an award-winning collaborative process, engaging a broad coalition of architects, social and healthcare organizations, and research teams from the EU-funded DREEAM project, alongside residents, neighborhood committees, and 1892 staff. The approach adopted encompassed both conventional and innovative technological solutions, including the implementation of PV energy storage. Additionally, the initiative aimed to diversify the social composition of the neighborhood by inviting various groups to reside within the estate, such as singles, families, retirees, students, artists, couples, or occupants of shared flats. To address diverse needs, the architectural strategy incorporated adaptable housing sizes and layouts, as well as the transformation of existing units into communal and public spaces, fostering a heightened sense of community and belonging. The rent increased by 1.05€/m2, but this was outweighed by energy savings. The total costs were reduced.

Description

The cooperative housing estate "Nettelbeckplatz" traces its origins to the era of stringent refurbishment strategies of the 1970s, which aimed to replace the so-called "Mietskaserne" (tenants' barracks) characterized by dimly lit rear courtyards and inhospitable living conditions. During that time, an official renewal program mandated the complete demolition of these old building areas to construct "modern" social housing structures. In 1973, the housing cooperative "1892" participated in this program, erecting a building complex reaching up to seven levels high, situated in the traditional workers' quarter of Berlin-Wedding. The original 175 apartments were arranged around a verdant courtyard featuring playgrounds and recreational spaces. The cooperative served as the cornerstone for fostering a robust local community grounded in self-help, solidarity, and self-organization.

Four decades later, the effects of demographic shifts are evident, with over 40% of the residents surpassing the age of 65. Many inhabitants now require barrier-free accommodations or assisted living options. The once-vibrant community has seen a decline in vitality and influence within the neighborhood. Moreover, the state of the building structure has deteriorated, necessitating renovation. In addition to inadequate energy standards, certain entrance areas and floor plans no longer meet contemporary needs. Compounded by social issues in the surrounding disadvantaged area, an atmosphere of insecurity and social decline has emerged.

The renovation project focused on upgrading the thermal and technical conditions of the existing building. Measures included roof insulation, window replacement, and the installation of solar panels. Furthermore, to enhance comfort and reduce heating energy consumption, windows were substituted. Renewable energy production, utilizing photovoltaic panels on the roof for common areas, was augmented with a battery storage system (Tesla PowerWall) for optimal community utilization of generated energy. Elevators were also refurbished.

The open ground floor area, where security concerns such as drug consumption were prevalent, was closed off. However, the section connecting two courtyards remained open. New dwellings were constructed in these remaining ground floor spaces to accommodate student and elderly residents, alongside the addition of communal areas, fostering a more diverse and interconnected community.

Residents actively participated in the project, engaging in a study within the DREEAM project to monitor energy consumption trends in the neighborhood. A trained group of residents exhibited 30-50% lower energy consumption compared to the control group, showcasing significant energy savings. The reduction in energy consumption, as demonstrated by the DREEAM project, was as high as 50% compared to pre-renovation measurements.

This project serves as a blueprint not only within the housing cooperative "1892" but also for other community-oriented investors. In the context of increasing urbanization, particularly in Berlin, and to counteract speculation, interdisciplinary approaches are essential to synthesize quantified growth, intelligent building design, affordability, and social values into sustainable developments. This innovative project integrates various aspects, including the renewal and further development of housing estates through multi-building strategies and integration into the surrounding neighborhood area. Insights gleaned from this project could inform the development of similar urban strategies in the future. Additionally, the project underscores the value of employee motivation stemming from involvement in a European project, providing opportunities for cross-cultural exchange and learning from counterparts in other countries.

Description

The residential complex is situated on the periphery of the Slovak capital on the edge of a large housing estate from 1970s and the fabric of scattered family houses. It lies on a hillside with southern exposure and an attractive view. The complex consists of four residential buildings with 64 mainly 1- and 2-bedroom apartments, which are complemented by kindergarten and rentable spaces for services and offices. Below the surface the parking garage for residents and visitors is situated. The central longitudinal public space is clearly articulated in terms of sloping ground and runs into the community garden. The private gardens that are part of the ground floor apartments run into the community garden as well. On the top floors of all four residential buildings are roof apartments with large green terrace, designed as a "house on a house".
The residential complex tries to solve the typical problem of periphery, where new developments meet the modernist housing estates and scraps of original rural settlements without solving the relation to the surroundings and without creating any added value in the form of public space and services. Our aim was to eliminate such negative effects of densification and exploitation of the territory. We have designed the complex in a form of pavilions that articulate the open spaces in correspondence with the urban planning principles of the housing estate embodied in the semi-enclosed courtyards. In the same time the new complex reflects the low building structure of the surrounding family houses. Unlike neighbouring monofunctional new developments the complex is hybrid structure that integrates housing, kindergarten and rentable spaces for commercial use. The residential houses are of hybrid nature when associating three different types of apartments all with large balconies, terraces or gardens with attractive views. The complex brings spatial and functional diversity to the city periphery and integrates it into the urban context.
Residential complex is realized as a reinforced concrete skeleton with brick infill. Skeleton enabled variability in ground plan solutions and integration the residential function and facilities in one building. At the same time it allowed the implementation of large glassed walls on the south facade overlooking the valley. Plastered facades surface refers to the housing blocks from 1970s and the neighbouring family houses. The stronger colours used in the housing complex help in the same time to distinguish it from the surrounding. Plaster is complemented by the wooden shutters – shades. Their elementary geometry refers to the picturesque back yards of the neighbouring old family houses. Southern exposed façades are in the same time framed in to compact stereotomic frames, which are visible especially in long-distance views on the exposed area. The choice of a simple material solution is also a direct result of the construction costs limit and subsequent marketability of apartments. The lower demands on maintenance correspond to the general low cost strategy.

Description

Condominium Devín is housing complex in frame of the historical village structure situated in the Bratislava-Devín District, in the protection zone of the national cultural mo-nument - Devín Castle. Family houses create together a system of intimate spaces. However, on the side of the street, houses try to create a suitable mantinel for a pleasant stay in the public space. From the street, the facades of the houses are irregularly graded, making it a colorful vista and exterior spaces. New alley is integrated in the existing system of a streets of the old village under the castle rock.
New residential neighborhood in the village intravilan. A smaller scale of shared housing, a direct confrontation with the surrounding urban and historical context. Creation in a complex cultural and physical environment.

The resulting structure has formed a multi-stakeholder dialogue. Architects have tried to find a penetration between often conflicting requirements and to bring a slightly different view of housing. As a result, there is a rugged "villainous" residential structure with well-differentiated semi-public, public and private spaces, which gives the inhabitants plenty of intimacy.

We see that there is a "fair mess" in this project. There are flat and sloping roofs. Oriented sometimes by a street shield, sometimes on the other side of the street. The individual objects do not respect any unambiguous regulation applicable to all houses, no regulation, no prescribed uniformity. In spite of this controlled chaos, the result is a very interesting composition. Not only in terms of "high architecture". The result is an natural growing urban structure.
The objects have vertical load-bearing structures made of hebel brickwork. Horizontal structures are made of monolithic reinforced concrete ceilings. Prefabricated structures are made of reinforced concrete prefabricated structures, anchored through thermal insulated baskets (so-called iso-hulls). The foundations were made on base strips and thin reinforced concrete slab. Finishing facades are made of thin and coarse-grained plasters. Aluminum windows were planted in window openings.

Description

Winning scheme of a European competition organised by the developer, the Savonnerie Heymans complex reflects a truly sustainable approach by recreating a real new neighbourhood of 42 low-energy and passive social accommodations including apartments, lofts, duplexes and Maisonettes. Although a 100% public housing scheme, thanks to the diversity of its program the Savonnerie Heymans provides a variety of spaces echoing the diversity of the people living in the very heart of Brussels. Glass-enclosed bioclimatic loggias characterise the entire complex, providing an effective acoustical and thermal barrier but also providing a sense of privacy.

On the 6,500m² site of a former soap factory less than half a mile from the Grand’Place, the social housing project creates a real “village” of 42 sustainable accommodations of different types including studios, 1 to 6-bedroom apartments, lofts, duplexes and Maisonettes.

Although a 100% public housing scheme, thanks to the diversity of its program the Savonnerie Heymans provides a variety of spaces echoing the diversity of the people living in the very heart of Brussels. Glass-enclosed bioclimatic loggias characterise the entire complex, providing an effective acoustical and thermal barrier but also providing a sense of privacy.

Considering Brussels’ rapid growth in population, the scheme features high density accommodations equipped with amenities such as a room for social meetings and events, a crèche and extensive public space: the “Mini-forest” garden, the 3D landscaped park and playground and the main promenade.

All the existing valuable - but not listed - historic buildings and elements such as the chimney, the main 19th century house on the street and the postal relay were retained and integrated into the complex (the 40m high chimney, for example, was used as part of the underground garage ventilation system).

The glass-enclosed bioclimatic loggias provide each housing unit with a state-of-the-art acoustical and thermal barrier requiring no expensive/complicated services to run and lowering considerably energy consumption. The Loft building has been treated one step further as thanks to super-tight insulation, the building is now considerate “Passive” and requires less than 15 Kw/m2 per year to heat.
Located on the site of a former soap factory, the decontaminated land now welcomes a high-density social housing complex that provides a series of private outdoor spaces allowing its occupants to interact easily with each other and creating a convivial, village-like atmosphere.

The scheme was intentionally developed around the concepts of sustainable development (socially, economically and environmentally) and relies on low-serviced buildings. The glass-enclosed bioclimatic loggias provide each housing unit with a buffer acting as a state-of-the-art insulation tool lowering considerably energy consumption and protecting from the city centre noises. They also allow sharing the variety of arrangements of the semi outdoor space of each individual unit.
Beside the loggias, the scheme also features a collective heating system for the entire site (cogeneration), sanitary hot water heated by 60m² of solar panels, rainwater harvesting and natural materials for insulation (hemp fibres, expanded cork etc.). Whenever possible, existing buildings and structures have been retained and reused.

Description

Since 2005, the state of Vorarlberg has been committed to building an energy-efficient building culture, particularly in integrated housing construction. This also includes a high-quality and resource-conserving building, in which economics and ecology, social and culture are in harmony.

For the new residential complex in the center of St.Gallenkirch these ideas are deduced from the local volumetry of the solitaires on the slope and applied to the new building.

a clear construction body is deliberately placed at the dedication limit and turned to the found slope.

This creates with the surrounding buildings and terrain edges, strong local-spatial relations such as to the church as well as the distant Silvretta or the Gweilgroup.
In the Montafon, the settlements were often built near the bottom of the valley in favor of the higher and better-sheltered soils on the mountain. This rural value is opposed to the reduction of the daylight of the valley. The new residential building is located on the valley's lowest settlement boundary.

A resource-conserving strategy and considerations of cost-effectiveness allow new ways to recover the lost light. Thus almost every apartment - apart from the last level on top of the building - has about eight square meters of air space over two floors. Nature and light penetrate these openings deeply into the interior and they leave the views to the outside in the distance linger.

The rooms of the apartments overlay each other and layer themselves over the floors in a central "supply core".

This high flexibility of the basic design results from the modular development concept. It is like a tetris with many solutions.
The conceptual simplicity turns itself as it were from the inside outwardly.

The energetic supply strings and the wet rooms are located around the central development zone of reinforced concrete.

Between this zone and the outer skin in a multibox construction lies the adaptable range of variance instead of addition - even in the third dimension.

The reflections on the interior are also visible in the façade.

The room-high, prefabricated riftboard elements form the frame for the lower multi-box and give the building a pleasant tectonics. A single window type is added according to the inner texture.

Description

3 blocks of 20 dwellings that are built along the two streets; Neppert and Buhler and define a collective small garden in the middle.

The aim of the project is first defined in terms of quality of living :

- to create dwellings with surfaces bigger than standard.

- to offer additional and intermediate spaces with characteristics that differ from traditional rooms in an individual house and that widen the possibilities for usage, the diversity of spaces and the climatic conditions.

- to bring the collective housing close to the qualities of an individual house in developing outdoor spaces that extend the indoor rooms.

- to optimize the number of dwellings in comparison to the plot capacity in order to develop an efficient project economy that allows to create the largest possible surfaces for the housing.
The objective shared with the client was to create an innovative project with typologies that differ greatly from standard. The aim is to create a diversity in housing and a social mix, an attractive housing scheme in an area that is little sought after.

The flats, from T1 to T5, offer various plans and typologies of one-storey and duplex apartments.

The housing units offer surfaces that are nearly twice as large as a standard dwelling but nevertheless within the same budget. They offer living spaces in a dense urban environment that are comparable to those of a house.

The density, the maximum use of the right to build on the site, the combination of typologies, the effective construction system along with collaboration with the developer have all combined to allow for this generosity in space whilst also creating a large number of dwellings.

All the flats are dual-aspect. The living rooms, (south east orientation and a 10m wide façade), open on to a terrace that can be fully closed in winter.

These winter gardens, largely open in summer, define a bioclimatic system with a wide natural ventilation.

They offer an extra space supplementary to the living rooms, like a private garden.
The efficiency of the structure is the key point in the economy of the design that allows for the creation of oversized surfaces without an increase in construction cost.

The 3 buildings are designed on the same principles of construction: a post and beam structure with reinforced concrete slabs, using prefabricated elements. The 10m grid, without intermediate posts, defines the width of the dwellings and allows for the creation of large spaces that are not constrained by the structure.

The facades consist in fully glazed sliding framework and are equipped with thermal curtains and shading devices.

The winter gardens are closable in winter with the use of aluminum framed shutters clad in transparent polycarbonate. These are sliding shutters that come to stand on one side of the balcony.

The bioclimatic concept performs in terms of energy saving and fulfills a good standard of low energy construction.

The winter gardens create an intermediate non-heated space that plays a very active role in the thermal efficiency. They improve and naturally moderate the normal external conditions by creating a buffer volume, very favorable in terms of energy saving.

Description

The complex includes 8,500 m² of residential units – 23 apartments (phase 1 – built) and 10 single-family residences (currently under construction), all integrated into the surrounding landscape of the Tallinn’s picturesque historic garden neighborhood of Nõmme.

The project was defined by its site and the local zoning regulations which restricted the amount of developable space to a maximum of 33 housing units (600 m2 of plot area per unit) with a very low total FAR. Thus, the overall concept of the project became to be “Buildings in the park”.

The apartment houses are put into a relatively dense arrangement on the western side of the site to provide for a more urban/communal atmosphere, in contrast to the rest of the development which is comprised of individual buildings placed discretely into the site. The parking level is located under ground, reducing the bulk of the development and tying the buildings together both under ground and above via a communal public space. Between the apartment houses and the private residences there is a water feature, embellished by a sculpture which provides for a picturesque living environment for the residents.

There were a number of factors that defined the solution for the facade of the apartment complex.
First and foremost, it was the picturesque environment in which the complex was to be placed. The architects wanted to blend the complex into the environment, but to do it in a modern way. Thus, it was decided to go with copper cladding. Given its chemical properties, copper will turn green over time, letting the building age elegantly while slowly blending into its surroundings.

Using copper was also dictated by the will of the architects to merge the roofs and walls of the buildings. In Nõmme, the picturesque historic area of Tallinn, the zoning regulations restrict the maximum bulk of buildings to two floors with a half-floor attic.
While typically this results in a default gable-roof typology, Alver Architects used the restriction as a creative form-generating tool, while using copper to visually merge the walls and the roofs of the buildings. The result is a development which while conforming to the regulations, still boasts a unique character, and generates extra value for the developer.

The stripy texture of the facade of the apartment houses was a solution to the tight budget constraints. As it is cheaper to procure thin stripes of copper rather than large uniform panels or sheets, the facade was composed of thin copper ribbons of different length and width. Once the copper facade was laid out, the windows were placed into it in such a way that they matched the module of the facade, while following the inner logic and insolation requirements of the apartments inside.
