Riad à tiroirs

This 200m² property is designed according to specific rules: autonomy, respect for natural cycles, compactness and complexity. The main difficulty has been to reproduce accelerated natural cycles on a small scale (water cycle, cycle of organic matter, energy cycle) and then merge the various devices related to these cycles within the architecture. In addition to endorsing these technical devices, this architecture is innovative in terms of occupancy space strategy. Being modular, it allows nomadism as needed (use change, transformation or reduction of spaces) depending on e.g. the seasons or the number of occupants (modification of the division). There is no fixed space to which a function is assigned; in this house everything changes and moves. The cybernetic approach is based on the relationship between the elements of a system in equilibrium.
