The Government of Canada has announced the winner, David Chipperfield Architects in association with Toronto-based Zeidler Architecture, and the finalists of the international competition for the redevelopment of the Parliamentary Precinct Block 2 site in the capital of Ottawa.

The design, by David Chipperfield Architects in teamed with Zeidler Architecture, is defined by a new interconnecting garden atrium and timber-framed structures that combine with a set of sustainability concepts and dedicated two-building space for Canada’s Indigenous Peoples, to offer the country a renewed complex at the heart its national seat of power.
Team description: “Our proposal weaves together old and new to create a rich tapestry of past, present, and future. In the spirit of responsible stewardship, existing structures are given fresh purpose. The value of this built heritage is unlocked by a new net-zero building and public spaces that represent a bold new architectural expression of Canadian identity.”

The winning proposal was followed closely by designs from Renzo Piano Building Workshop and the Canadian firm NEUF Architects, which placed second, Watson MacEwen Teramura Architects and Behnisch Architekten which placed third, and other shortlisted entries as the team by Diamond Schmitt Architects and Bjarke Ingels Group, KWC Architects, ERA Architects, and other shortlisted entries by Provencher Roy and Wilkinson Eyre (in association with IDEA Inc.).
 
"The redevelopment of Block 2 will transform this mix of ageing buildings into modern, inclusive, sustainable, secure and accessible accommodations for the Parliament of Canada. I truly hope that all Canadians will be able to visit and experience the chosen design, for years to come."
Canada’s Public Services and Procurement Minister Filomena Tassi.

The project is expected to commence within an 18 to 24-month timeframe.
 

Project description by David Chipperfield Architects

Block 2 is located immediately south of Parliament Hill in downtown Ottawa. It faces the grand Gothic Revival buildings of Canada’s Parliament, defines the fourth side of the Parliamentary Lawn and marks the threshold between this symbolic civic space and the city. Bounded by Metcalfe, Wellington, O’Connor and Sparks streets, the site encompasses eleven buildings of varying size and condition with several layers of heritage designation.

The redesigned block will provide office space for the Senate and the House of Commons and will allow for the future consolidation of parliamentary accommodations, including space for the Library of Parliament. It will also include renovated retail space on the Sparks Street Mall. As a site of national importance, the project carries a responsibility not only to provide the facilities for democratic government and urban infrastructure but also to represent the values of a nation and a vision for its sustainable and inclusive future.

The Indigenous Peoples’ Space, a building not part of the redevelopment scheme, sits in the centre of the block. The project proposes a new public square adjacent to this building and on axis with the Peace Tower, an open space to promote dialogue between Parliamentarians, the Indigenous community and the wider public.

 Stewardship of the land and resources is a concept embedded in Indigenous culture. It is also a tenet of good governance, sustainability and heritage conservation, and the basis for a design approach of minimal intervention and maximum retention for Block 2. Throughout the site, demolition is largely avoided, and new elements are designed for the circular economy, incorporating recycled materials such as reclaimed copper in the facade, with new materials designed for disassembly and future reuse. The development will be net zero for carbon emissions, incorporating a timber frame, highly insulated facades, and on-site renewable energy generation.

Across the block, historical structures are woven together with new low-carbon, efficient buildings to create a diverse, characterful, yet coherent whole. This is facilitated by a simple floor plan on both the east and west sides of the block. The six buildings of Block 2 East, containing offices for the Senate of Canada and two large committee rooms, are connected by communal spaces with winter gardens. The five buildings of Block 2 West, containing offices for Members of Parliament, are connected by the Garden Atrium – a covered courtyard that functions as a shared social space and acts as a thermal buffer to protect the existing buildings from the extreme Ottawa climate and provide a healthy working environment within.

Sir David Alan Chipperfield was born in London, England, on 18 December 1953 and grew up on a farm in Devon, southwest England. He studied architecture at Kingston School of Art, graduating in 1976, and at the Architectural Association School of Architecture in London, where he completed his studies in 1980. After working with Douglas Stephen, Norman Foster and Richard Rogers, he established David Chipperfield Architects in 1985.

His early commissions included the interior design of a shop for Japanese fashion designer Issey Miyake in London, which led to further work in Japan. His first major building in the United Kingdom was the River and Rowing Museum in Henley-on-Thames, completed in 1997. As his international activity expanded, the firm opened offices in Berlin (1998), Shanghai (2005), Milan (2006) and Santiago de Compostela (2022), in addition to its London headquarters.

Over the following decades, Chipperfield completed more than one hundred commissions across Asia, Europe and North America, encompassing civic, cultural, educational and residential buildings, urban interventions and the restoration of historic architecture. In Berlin, he directed the restoration and reconstruction of the Neues Museum (1993–2009), followed by the construction of the James-Simon-Galerie (1999–2018) on Museum Island.

His other works include the Veles e Vents building in Valencia (2006), Turner Contemporary in Margate (2011), The Hepworth Wakefield (2011), the extension of the Saint Louis Art Museum (2013), Museo Jumex in Mexico City (2013), the Amorepacific headquarters in Seoul (2017), the extension of the Royal Academy of Arts in London (2018), the West Bund Museum in Shanghai (2019) and the extension of Kunsthaus Zürich (2021). His interventions in existing buildings also include the restoration of Mies van der Rohe's Neue Nationalgalerie in Berlin (2021) and the refurbishment of the Procuratie Vecchie in Venice (2022). More recent works include Casa RIA in Santiago de Compostela (2024), Arena Milano (2026) and the transformation of the former Bank of Spain building in Santander into Faro Santander (2026).

Alongside his architectural career, Chipperfield has taught at institutions in Europe and the United States, including the State Academy of Fine Arts Stuttgart and Yale University. In 2012, he was curator of the 13th International Architecture Exhibition of the Venice Biennale, entitled Common Ground, and between 2016 and 2017 he participated as an architecture mentor in the Rolex Mentor and Protégé Arts Initiative. His publications include On Planning – A Thought Experiment (2018), and in 2020 he served as guest editor of the Italian magazine Domus.

In 2017, he established Fundación RIA, an independent non-profit organisation dedicated to research and sustainable territorial development in Galicia, Spain. The foundation works on territorial planning, environmental issues, local economies and cultural heritage in collaboration with public administrations, institutions and local communities. In 2024, it inaugurated Casa RIA in Santiago de Compostela, a historic building refurbished by David Chipperfield Architects that also houses the firm's Galician office and accommodates a public programme of lectures, exhibitions and other activities.

Beyond architecture, he has developed furniture and product designs in collaboration with international manufacturers through David Chipperfield Design. In 2026, Casa RIA presented Design for Living, an exhibition bringing together more than fifty objects, prototypes and drawings produced over a period of thirty-five years.

Chipperfield is a member of the Royal Institute of British Architects (RIBA) and an honorary member of the American Institute of Architects (AIA) and the Bund Deutscher Architekten (BDA). He received the Order of Merit of the Federal Republic of Germany in 2009 and was knighted for his services to architecture in 2010. His professional distinctions include the RIBA Royal Gold Medal (2011), the Praemium Imperiale from the Japan Art Association (2013) and the Pritzker Architecture Prize (2023). In 2021, he was appointed to the Order of the Companions of Honour in the United Kingdom, followed in 2022 by his appointment as Commander of the Order of Isabella the Catholic in Spain and his admission to the German order Pour le Mérite for Sciences and Arts.

Zeidler Architecture has been creating meaningful spaces for people to connect for over 65 years, with considerable experience in master planning, urban and architectural design. The practice was founded by Eberhard Zeidler. They are a leading Canadian architectural firm that brings together the experience of more than 100 professionals, collaborating nationally across their Toronto, Calgary, Vancouver and Victoria offices.

Their portfolio spans a broad range of work including residential, commercial and mixed-use properties, civic and academic buildings, healthcare and research facilities, performing arts centres, hotels and resorts, and transportation. 

Eberhard Zeidler (Germany, Braunsdorf, January 11, 1926 – Canada, Toronto, January 7, 2022) was one of the last living links to the Bauhaus school and the man responsible for some of Canada’s most significant mixed-use urban developments including Ontario Place and the Eaton Centre in Toronto. He was instructed under the influence of the Bauhaus school in Weimar and the Technische Hochschule Karlsruhe. He fled East Germany and worked in the office established by Emanuel Lindner, his former professor. There, he constructed several factories and medical buildings. Zeidler subsequently immigrated to Canada in 1951.

Zeidler first joined an architectural firm with Blackwell and Craig in Peterborough, Ontario. He later relocated to Toronto in 1963 and worked for the firm became Craig, Zeidler and Strong until 1975. One of the essential elements of his early works is his employment of striking interior atrium space, which became widespread on an international level during the 1970s. Moreover, his experience in the Bauhaus school made him familiar with the technological matters in building design. These included structural and mechanical services (most notably, exposed air-handling ducts), as well as aspects that ease movement and communication. This was exemplified in the McMaster University Health Science Centre, his breakthrough project, which was meant to resemble a large construction set for children. The building utilized regular geometric building modules, coupled with glazed service and circulation towers, internally exposed steel trusses, ducts, and an automated materials delivery system.

Most of Zeidler's structures were public buildings. He rarely designed private residences, drawing up approximately 20 in his career, most notably the four-storey home in Rosedale that he constructed for his family during the late 1960s. He officially retired in 2009, but continued to go to work daily as a senior partner emeritus at the firm, now called Zeidler Partnership Architects, in Toronto. The firm also has offices in Calgary, Victoria, BC, London, Berlin, Beijing, and Abu Dhabi. He also taught at the University of Toronto as a visiting lecturer and critic, before working as an adjunct professor from 1983 to 1995.

Zeidler was appointed an officer of the Order of Canada in June 1984 and invested four months later in October. He has also received the Order of Ontario that same year. He was conferred the gold medal of the Royal Architectural Institute of Canada in 1986. Three years later, he was granted an honorary Doctor of Architecture by the University of Toronto.[5] Zeidler was the recipient of the Queen Elizabeth II Golden Jubilee Medal (2002) and the Queen Elizabeth II Diamond Jubilee Medal (2012).
