HOUSING BLOCK C2 SUD

ALBIZZIA CONFLUENCE GIVES WOOD A STARRING ROLE

Albizzia will be the first timber-frame housing block in La Confluence. Located in the eastern part of the Rhône-Alpes region, it will be structured around a former market building transformed into a school. The watchwords of this development are mixed use, low carbon and nature in the city.

low-carbon wood construction

The C2 Sud housing block, located east of the Regional Council Building, on the corner of Smith and Montrochet, is the first timber-frame housing block in La Confluence. It’s an ambitious goal for a development comprising four buildings, including one high rise with 16 floors (53 metres). The buildings are covered with a mineral facade combining materials such as bricks, glazed tiling and terracotta to provide texture.

Wood, a bio-sourced material, reduces the carbon impact of the development. While they grow, trees absorb CO2. Once they have been cut down and used as a construction material, they continue to store carbon. The carbon savings are estimated at 6,000 tons of CO2: the equivalent of 106 years of normal household consumption. The buildings will use CLT (cross-laminated timber), which is more rigid and stable than solid wood.

Made of wood, the housing block meets the goals of a low-carbon neighbourhood and the need to develop the area around the new school quickly. The four buildings feature white mineral facades that highlight the presence of plants and trees at the centre of the buildings.  The design’s simple volumes require a sharp focus on the materials and on the architectural details, to ensure that the development is sustainable over the long term. ».

The use of wood also means that the project can be completed faster, with a timeframe that is 6 months shorter on average than a traditional project. In addition to prefabrication, which halves the time needed for the structural work, there is no drying time involved. This means that once the structure has been built, the finishing work can get started right away.  This is a huge advantage for a development that needs to be completed before the neighbouring school opens in the former wholesale market building, at the start of the school year in 2022.

Albizzia will be the first project in Lyon by Woodeum. A young property development company founded in 2014, in just a few years, it has become the leader in wood construction, with more than 30 projects. As a committed company, together with other stakeholders concerned about the climate, Woodeum founded the Association for Low-Carbon Buildings (BBCA). The objective is to raise awareness about the urgent need to reduce the carbon footprint of the construction industry.

Woodeum joined forces with UTEI, a historic player on the Lyon property market since it was founded in Lyon in 1960. UTEI works in both the residential and commercial markets, both as a developer and as a contracting authority on behalf of institutional clients.

 

The Albizzia development will have the BBCA label, a benchmark for measuring the carbon footprint of the buildings, both during their construction and while they are in use.
