A ground floor is transformed to architectural office with simplicity, creation, evolution and communication with the environment to constitute the parameters of its design. The clear lines of space and objects, the presence of wood and the targeted lighting with intensities and shadings according to uses, provide the office with the calm and comfort a creation area requires. In parallel, the sense of movement and volatility, through the design of the workbench and the library,encourage the evolution of ideas for architecture and the capability of the materials. Finally, the corner of the workbench and the lighting appliance welcome the visitor and invite him to “march” towards the design and construction of his own place. This march is supported with the opening at the back and the external lighting, which give the feeling that the office has no boundaries and extends beyond, opening dialogue with the surrounding area.
