Tilleuls
Tilleuls project is a typical example of housing in residential areas. Plot divided to generate profit, house too small, too much partitioned, not adapted anymore to the current lifestyle and not insulated. A typology of project that architectes will have to deal with more often to transform the existing situations, avoid land impact of new neighborhoods, and improve energy consumption of buildings.
The project quickly heads toward a renovation of the existing building, energetically and spatially, completed by an extension.
The partition of the house has been redesigned. The side of the entrance is changed to face the street and create a filter between public and private. The ground floor inner space has been entirely transformed.
All the common spaces are placed in a unique volume, a large room fully open towards the garden.
The connection to the existing house is resolved by the plan, two curves that link the extension with the existing house. After passing through the entrance, with high ceiling and full of natural light, the visitor is guided by the curves to the central space, darker, and with lower ceiling, containing all the servant functions, as well as the distribution to the first floor. This compressed space contrasts with the high ceiling and garden’s perspective of the living space full of light. The sloping roof extends the movement dynamic from the entrance to the garden. The color on the two curves bring joy and softness in this white and bright space
The extension is constructed in large insulating bricks and wooden framework, on a concrete elevated slab and micropiles. The underneath of the wooden beams are kept visible in reference to Japanese spaces. The walls and roof are both insulated respectively with 7,8 inches and 11,8 inches of wooden fibers to guarantee the best thermal comfort possible. A heating floor brings an optimal distribution of the heat.
The path of the sun is made visible in the house’s floor by the oculus drilled into the roof. At night we can observe the stars through it.
Seen from the garden, the extension envelopes the existing house. The blue zinc dialogue with the existing tiles. The integrated gutter allows to slim the edge of the roof and make it more abstract. The overhang roof protects the windows from the rain and direct solar radiation in summer, completed by a thermal curtain.
The large window is made of 8 panels that slide allowing different links between inside and outside. It is extended by the miroirs on both sides that makes the wall edge disappear.
Geometry guides all the conception steps: in plan, in elevation, and in the fixed furniture. Color reveals the spatial elements.
