CFL administration building
A sober, flexible and comfortable office building designed on a highly complex urban site, constrained by the railway line.
The team has designed a building that is both linear and fragmented, with elements organised on either side of a central hall to capture the spirit of the railway as a place to live and share. It makes the programmes it accommodates and serves flexible. It creates a meeting place in a space bathed in light and thermally comfortable. Footbridges on all floors link the different parts of the building.
Vegetation is very much part of the design: in addition to the surroundings, it can be found in the patios, but also inside the central hall and on the roof terraces accessible to users. A railway landscape, made up of landscape strata demarcated by rails inserted into the ground, ensures continuity between the public spaces and the interior street. The walls of the gabion base will support climbing vegetation.
Tomorrow’s tertiary sector must be domestic, and we have paid particular attention to its use. With the large hall, occupants have access to semi-outdoor spaces that are thermally comfortable, allowing them to work on the move. The vertical and horizontal corridors are transformed into living spaces where informal working and relaxation can take place.
Acoustic comfort is one of the project’s major challenges. We are limiting noise from the outside by installing high-performance façades incorporating a double-skin complex to meet the desired acoustic requirements (BREEAM excellent + WELL platinum). Interior acoustic comfort will be provided by coffered floors with an absorbent underside, with occasional reinforcements on the vertical walls in the interior street.
