Prototype housing is designed to accommodate people in a temporary situation, the prototypes would be used by the population living nearby, whose habitation is found unavailable for works, fire, or if the city needs extra accomodation. Thus the project had as assumptions such contingency conditions and changeable with respect to time and use of the prototypes. Each prototype should accommodate at least three people, without being deprived of the basic needs: hygiene, accessibility, meals, rest (...)

Moreover fot the project should also be taken into account the possible aggregation. Furthermore, the prototype should have maximum area of 30m2 and 120m3 maximum of volume.

To develop the project, were taken into consideration the concepts of comfort, flexibility and adaptability; server space and space served, public space and private space, function space and visual space, equipment and furniture; structure and distribution; facade and surroundings.
Initially the project sought to define a structure for organizing and generating spaces. The principle of the project was the placement of the "motor" (made ​​up of the areas of water: sinks, toilets), which define the space immediately told private (zone of personal hygiene and sleep) and public space (living area / dining ).Since that the motor serves both public space prototype as private space, for reasons of accessibility it is placed between these spaces, thereby establishing the boundary simultaneously between public / private. During the project, for better optimization of space, structural axis were established. The prototype resumed as ideal model, prototypu < Gr. protótypos, model; f. m.,first type; model; standard; the most perfect model. Thus, after an exhaustive and meticulous space articulation, it was possible to reach a generating metrics that organizes the spaces; the space is organized in a grid grating (1.40mx 2m). The concept is expressed as modules within a module.
