A former bank office becomes, once again, a home. Once rudimentary, the townhouse was transformed into a reception with office space with a concrete vault at its heart. Stripped down to its primary structure, the remnants of both lives are made visible.

Perpendicular to the direction of the original three-part townhouse plan, a strip model is projected. This radically new organisation incorporates both the vault and a new rear extension, stretched between the plot boundaries, into its logic. Where necessary, it cuts away, modifies or supports. The choices made remain visible and merge with the previous ones. The new extension in cross-laminated timber continues the language and texture of the existing concrete ceiling. A generous opening in the upper floor provides light and opens to the rooms above via a spiral staircase. The massive vault is given a patio as a mirror image.
