This project won the Grand Prize of the jury of the Trophées Bâtiments Circulaires 2023 in the “Public project owners – tertiary buildings” category.
Rehabilitation of an abandoned commercial wasteland into a Social and Solidarity Economy (SSE) Centre with the use of reused materials (radiators, sanitary facilities, doors, lighting, parquet flooring and rainwater recovery system). Soil unleasing with the creation of a landscaped valley and installation of 300 photovoltaic panels for a power of 1000Kva/year.
Building users opinion
Satisfied. The project was undertaken with the future tenants.
If you had to do it again?
Reused materials pose constraints related to regulations, insurance and supplies.
The parallel creation of the Plateau Circulaire in Caen made it possible to secure the materials, restore them if necessary and focus on the finishing work (radiators, sanitary facilities and doors), which are easier to insure.
The establishment of a cross-cutting “reuse” criterion and batch no°1 dedicated to reuse was relevant, as was the support of an Assistance to the Contracting Authority specialised on the subject.
