The major restructuring of this ordinary modern heritage asset reveals its potential for transformation. Built in the 1960s, the buildings are based on a regular reinforced concrete structure. Without insulation and altered by successive additions, they had become dysfunctional. Following strip-out, asbestos removal, partial deconstruction and strengthening of the existing structures, the project consists of a timber-frame vertical extension and addition, provided with a high‑performance thermal envelope. Two new covered playgrounds, positioned perpendicular to the main building, redefine the schoolyards.
