Transparence through matériality. How to integrate an executive office, a meeting room and ten desks in an initial volume of 100 m2. The master plan of the four large tables overcomes the programmatic limitations by extending themselves through a transparent partition. We choose to implement flexible PVC panels which are commonly used for industrial insolations in cold rooms or clean rooms. Cut into 220cm elements, PVC is pinched between cleats and stretched vertically. Its 5mm thickness gives it a very good sound absorption and an outstanding resistance to tearing. Thus we were able to keep spacial and light qualities of the space by composing with an innovative and transparent partition, 6 times cheaper than glass walls.
