Hyperion will be the highest residential tower made of wood in France, in the city center of Bordeaux, close to the new TGV (high-speed train) station. 

In Bordeaux, France, the Saint-Jean Belcier area is part of a wide urban renovation program. The project for this site is to unite the necessity for the area to regenerate itself while being an ambitious showcase for the metropole following in the footsteps of the main phases of a wider city planning and development project for the old town. 

Located where rue Carle Vernet meets rue d’Armagnac, the Hyperion project features three buildings with a total of 176 housing units, an underground parking ramp on two levels, an office building, and shops.

Named from the world's tallest tree, the wooden structured Hyperion tower rises from this complex.
With a total height of 55 meters, the 16-story tower is composed of 98 housing units circling a central core (elevators and stairways). The core, as well as the first three levels, is made of concrete. This rigid spine is completed by a wooden structure of beams and poles. The hard-wood floors and partitions are made of CLT wood (Cross Laminated Timber). This material assures modularity and security to the building.

Under Eiffage Construction oversight, wood materials are from local industrial productions. From the forest to the construction site, traceability is guaranteed by an identified label. This short circuit policy is a step forward in low carbon construction means. The specific bio-sourced, renewable and low carbon wood produces 25% less CO2 than concrete in structural work. This will allow the tower to store the amount of 1 000 tonnes of CO2.

On site, construction of a wooden structure building brings several advantages:
Hyperion composition will involve more than 1.500 wooden pieces assembled on site, reducing the time for structural work in half; Consequently, noise disturbance, due to truck rotations, will fall down to 6 times less than usual.

While maintaining a reduced amount of land hold, the Hyperion tower is an architectural and technical wonder, taking full advantage of BIM technology and thorough work coordination.

Surrounding the tower is a 9-story building composed of 54 units of social housing and 22 properties. A second lower building nearby is dedicated to offices while both ground floors house shops.

The notions of freshness, seasonality, shade, and quality of public space are key to the landscape project and inspire every level of it with green spaces and car-free lanes.

Hyperion is one of the leading projects launched by BBCA, a French non-profit organization, in 2016. Awarded on multiple occasions, from the "Grand Prix Régional" and the "Prix de la Mixité Urbaine" at the Pyramides d'Argent to the "Grand Prix National" at the Pyramides d'Or, the project has been crowned "BIM d'Or" for the 2019 edition.

While completion for the wooden tower structure is scheduled for May 2021, surrounding buildings will be delivered on September 2020 and offices in January 2021.
