This building is composed of two entities linked by a sharedlobby: a library (rehabilitation) and a multi-purpose hall(construction).A mixed program served in an architectural design, where agame of simple and readable volumes, each incorporatinga functional cluster, is differentiated by materials processing.The project is built around the reception spaces and acourtyard garden under control.The garden itself can structure the space, like a cloisterwhere the spaces and functions eventually meet.The linear frontage device is important. Indeed in order tominimize the visual impact from surrounding houses, theproject extends as much as possible. A project carved by itsprogram through with its volume is obviously becoming morecomplex in its division.Developing its own identity, this project is subtly inserted in itsenvironment.
