Within the existing concrete and brick building of undeniable heritage value located at 14 rue Max Jacob, the rehabilitation project provides for the installation of two distinct daycare units operating in seamless harmony.

In this project, we did not treat heritage preservation as a constraint, but quite the opposite—as an asset, seeking to play with the building to bring out its qualities and enhance it.

The design focuses on an interplay of frames and transparencies in which the existing horizontal concrete band acts as a second ground line supporting the proposed extension while marking the distinction between the first and second levels.

We designed the rooftop addition within the existing building envelope, giving it an identity of its own that responds to that of the lower level. It thus integrates through a contrast between horizontality and verticality, accentuated by the façade rhythm that plays on the alternation of solids and voids between the new timber joinery.

The extension is thus lightweight in both its materiality and integration, providing the various interior spaces with a continuous, controlled supply of natural daylight and ventilation.
