TILLEULS HOUSE EXTENSION
Tilleuls project is a typical example of housing in residential areas . The plot was divided to generate profit , the house was too small , too much partitioned , not adapted anymore to the current lifestyle , and noninsulated . 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 ’ s 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 a high ceiling and is full of natural light , the visitor is guided by the curves to the central space , darker , and with a 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 brings joy and softness to 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
