A low-carbon construction model
The Hypérion timber tower was selected for the Industrial Demonstrators for Sustainable Cities call for projects and is located near Saint-Jean station, in the centre of Bordeaux (delivered in 2021).
It was part of an urban renewal project carried out by EPA Bordeaux Euratlantique, in the Saint-Jean Belcier district.
The project was designed by Jean-Paul Viguier & Associés and developed by Eiffage Immobilier Sud-Ouest, with the assistance of Woodeum.
With its 1,400 m³ of solid wood, which serves as an effective carbon sink, this residential tower concentrates the equivalent of 1,000 tonnes of CO₂... A volume comparable to 9 years' worth of energy consumed by a building of this type.
The use of wood reduces CO₂ emissions from the project by 25%. Finally, over the entire life cycle of the building, it will save nearly 15 tonnes of CO₂ per dwelling!
The wood selected favours local production, as part of an environmental short supply chain approach.
This new-build development is fully in line with our low-carbon environmental approach.

Mixed materials and programming
Over 50 m high, the Hypérion timber-framed tower features 17 storeys and 98 dwellings over 7,000 m² of net floor area. The first three levels and the central core are made of concrete. The floors and partitions are made of cross-laminated timber (CLT).
The flagship building is flanked by a 9-storey residential building (78 dwellings over 6,000 m² NFA) and an 8-storey office building (5,000 m² NFA).
340 m² of shops at the foot of the building and 151 underground parking spaces complete the complex.
62 dwellings are allocated for social housing. The remaining 114 units are for private sale, including 38 reserved for social home ownership.
Winner of the BIM d'Or 2019
This operation received the BIM d'Or 2019 at the sixth edition of the awards organised by Le Moniteur and Cahiers techniques du bâtiment (CTB).
The project was praised for the logistical management of the prefabricated structures, the quality control applied to their installation, as well as carbon monitoring and reporting.
