Architectural surgery. A tribute was paid to a 1910 heritage building by removing all existing generic offices partitions and suspended ceilings, on every floor. The uncovered original concrete ceiling structure is entirely illuminated. Two triangular sculptures, a mezzanine and an administrative space, are carefully placed in the new 5.5-meters-high majestic main volume to create an architectural promenade for the users of this medical clinic. Precise symmetry is established in the entrance hall. Each office has the privilege of a sculpture, i.e. building columns or traces of its concrete.
