The project is built in an area surrounded by public facilities in a residential suburban character near Paris. The proposed extension is built while maintaining the wooded character of the bottom plot. The neighboring houses are built in traditional forms with gabled roofs, thereby extending the crib comes with a gabled roof curved. To insert the building in an environmentally sound approach, structure, roofing and siding are made entirely of wood components. Although the structure is wood, the generally rounded shape of the building is "born" of the desire to represent "...a boa constrictor digesting an elephant ..." This analogy refers to the stories of the famous story "The Little Prince" by paying tribute to Antoine de Saint-Exupery ... when he was a little boy.
The administrative departments of the city wanted to enlarge the capacity of this structure by extending the building housing an additional section of the 30 children.
This new part of building extension is composed of three spaces (an space activities and two sleeping spaces. The entire surface of the extension is 193 m². These three areas are unified by a single vegetated roof cover forming a whole and combining the three components of the program, however well differentiated.
Although the roof slope is performed with a plant complex to enhance the performance and thermal comfort in both winter and summer thermal inertia. As for the facade, the path is clear siding installed vertically due to the weaker form.
