A clear line runs horizontally around this structure delineating old and new, a heavy base level and light addition raising the original roof base line.

Designed by BAST and set in Toulouse, France, the added section creates an expansive high-ceilinged interior and lets in additional illumination via a generous skylight above.

The original building below is left largely as it was, its limestone walls bolstered as needed with new sections of concrete and its original angled roof removed.

And while the newer portion of the structure is clearly more modern, it still somehow manages to relate to to its function-over-form surroundings, remaining part of the neighborhood while still articulating the distinction between historical and new construction.
