Description :
Résidence du Lac 

The project is based on the central theme of the competition: housing as the manufacturing component of the city.

Our approach is thus based on the very precise work of the plan and a research of combinations that allows  from a very simple building with four facades to be produced all typological situations (1P, 2P, 3P, 4P, 5 / 6P) based on some principles: all appartments benefit from a double orientation, all appartments benefit from a living room always positioned in a the corner part, all apparyments are lit naturally  and have a  ventilated kitchen, all  appartments  benefit of  an exterior extension  of the living room,  generous and well dimensioned,  all appartments  benefit from a bearing, lit naturally.

We have tackled with the question of scalability in parallel with that of the economy: it is a question of finding the modalities of evolution of a dwelling, in a “space-price” relationship – by analogy with the “quality- price “- which exceeds the standard.

“The piece in more”

The project produces 60 dwellings (out of 132) with a potential extension, which we have called the room “in more”. This piece “in more” is out of water, out of air, not heated and especially not “normed”: it is not BBC, it is not H&E. It is an “extra” space of 10 m2 that everyone can invest immediately or later.

“Today I buy a 3 room appartment  but in a very short time, with very little means, I have an extra room, an office to work at home, a guest room, an extra bedroom because the family is growing …

“This room of 10 m2 “more” would cost much more with its corridor, electricity, BBC performance, heating, airtight joineries … In terms of residential course this flexibility and economy are a real lever. The very simple construction and technical principles of all buildings also allow for the flattening of the program and the reversion of housing divisions at any time.
