The general concept of this project is an ideal of a modular, flexible, smart and sustainble house built with local materials. This house, with adobe walls and skin in bamboo, has 50 m2 for a middle class family, consisting of two parents and two childrens. The heart of the house consists of a modular structure, fixed and closed, made of timber where the most deprived areas are located, such as bathroom, double room, storage, kitchen, and at the end a dinning room which merges with an open space around the module. This open space area allows the family to organize the house according to their needs an wishes: they can arrange a living room, an office and two rooms, for example. It should be noted that this house has a sloping ceiling with the more elevated part aligned with the area where the module is located. A staircase allows the family to access the to of it an enjoy from a flexible and versatile space, as well as, from a superior overview of the house. Being so flexible, this house can accomodate eight or ten people in the future.
