Abstract: A modular adaptable housing architecture for building temporary shelters and residential units in emergency situations is provided and includes an oval cross-section, which can be increased and extended in a flexible manner, involving the mechanically articulated assembly of successive structural modules formed by pairs of crosswise-arranged ovoid frames in order to support a panel-based inner floor slab, with the shell being formed by sheets, while providing a level floor solution in which the floor is elevated above the ground using the curvature of the elliptical supporting section of each frame or retractable supporting parts of the frames. The result is a self-tensioning geometry shelter, which can be adapted to suit the terrain and occupancy requirements, which is stable, strong and environmentally friendly, and which can be transported in disassembled parts and quickly assembled at any location without requiring any additional work and enabling a finish typical of the locality.
