This detached house is located on a plot of 2000 m² in the forest of Chantilly next to Paris .

Surgery :

The accommodation dates back to the 80’s and has an area of ​​about 200 m² . This renovation project is the result of a collaboration between Mr. Jean-Yves Prodel , consultant in Universal Design and Mr. Stéphane Du Bois , architect.

Quote from the design team Mr. Jean-Yves Prodel and Mr. Stéphane Du Bois  :The primary objective of this project is to facilitate the psychological and sociological changes that all people are likely to encounter in life. And with the products that one finds in the trade, it is possible to design a beautiful home that will adapt with age and new technologies .

This house originally had a narrow corridor that served the kitchen, bedroom, bathroom and toilet. The project consisted of rethinking the ground floor into a more open space including a kitchen with a central island overlooking the dining room and living room . The private areas  : bedroom, bathroom and wc have been enlarged for better circulation . The second bedroom has been replaced by an office with a 4 meter long picture window in the east and the construction of an extension of 100 sqm has completed the project to accommodate a swimming pool with spa, a garage Double and a studio upstairs. The location of a future elevator is planned in advance for the studio.

The electric heating system has been replaced by a geothermal heating system . And the whole house benefits from an electrical system in home automation KNX (Light, safety, opening, heating, communication).


The main access of the house is made by an electric gate with a surveillance camera , inserted in one of the pillars. The opening of the latter is done by a system of digicode and home automation . The height of the mailbox was chosen in order to be accessible in either sitting or standing . The path from the street to the door of the house, is done by a gentle slope , in asphalt,   less than 5% without rises .

External illumination:

The use of exterior crepuscular cells , directed towards the ground, for exterior lighting avoids any glare. This controlled system is programmed on a PC dedicated to the whole house automation system . It is also designed to work on I-Pad.

Interior lighting:

The focus was on maximum natural lighting through large windows and roof windows . The entire interior lighting system is managed by home automation .

Entrance :

The door is opened by remote control with color keys (intuitive use). The entrance door, made of solid wood, is composed of 2 magnetic suckers and a semi-circular handle   (ease of use). The adjoining wall has a window that provides natural lighting and allows to identify visitors from different heights. Installation of bay windows without bumping between the exterior and the interior.
