TRIANGO, the Belgian submission by BOPRO, winner of ‘Inventons la métropole du Grand Paris’


Bopro Sustainable Investments (BSI) won the development of 15 ha at the Triangle de Gonesse with its Triango. As a Belgian company we are now part of the ‘Inventons la Métropole du Grand Paris’ development.

‘Inventons la Métropole du Grand Paris’, the largest European competition on urban planning and architecture, was issued in 2016. This competition was searching for developments that would improve the quality of life in the Paris suburbs.

The judges chose the Triango project by Bopro sustainable Investments (BSI) for the Triangle de Gonesse project area – one of the 58 sites to be developed. The Triango site is located between the Charles de Gaulle and Le Bourget airports. A new metro station is planned from 2024.

Triango, an architectural entity by the RAU, Karres+Brands, SeARCH and Atelier Phileas team, will be a model of the circular economy. Together with its partners, including several start-ups, BSI will develop a site at Triango comprising 167 100m² modular offices, incubators, workspaces, co-working spaces. It also provides services and facilities such as a sports infrastructure, medical centre, crèche, … Businesses active in the bioeconomy belong at Triango. This development will definitely provide an answer to the needs of residents and entrepreneurs in Gonesse and its wider environment, but also to international companies. Conscious of the agricultural nature of the area, BSI has given high-tech urban agriculture a central place on this site. Here we plan approx. 10,000 m² of greenhouses and containers for the cultivation of plants intended for food, but also raw materials for bioeconomic activities.

The design is characterised by a central “sports” park that offers the maximum of “green” experience to the business areas around it. Where park-side offers variations to the differently designed building volumes, the continuous building along the edge on the outer side provide continuity and unity, giving the site a strong identity with iconic facades.

The buildings at Triango will be both energy positive and CO2 neutral. As the buildings are adaptable and can be dismantled fully this makes the project even more forward looking. In this context, any ‘stone’ used on the site, any material used – chosen based on its environmental performance and its capacity to be reused – will be recorded in the Madaster (materials database). As a result, any material used is traceable.

Finally, Triango stands for green mobility, therefore provision is made e.g. for bicycle parks, a carpool service and autonomous electric shuttles. A pronounced network of playful footpaths and well-designed cycle paths run through the green heart of the site. In the inner area there are solely ‘clean’ means of transport.

By 2030, Triango will provide 11,500 jobs, 68,500m² green space, 167,100 m² of usable surface area and 10,000 m² of high-tech urban agriculture.

Triango is a realisation by:
BSI (Bopro Sustainable Investments), Bopro, RAU, Karres en Brands, SeARCH, Atelier Phileas, ITF, LTF, Turntoo, BIGH, Urban Crop Solutions, SQA, Studio Beyond, Evergreen and Siemens.
