A modular adaptable housing architecture for building temporary shelters and residential units in emergency situations, comprising: an oval-cross-section housing body having: two tubular ovoid frames made of one of composite fibers and a metal alloy, wherein the tubular ovoid frames act as ribs of the oval cross-section housing body, and wherein the tubular ovoid frames have an upper section with an elliptical arc having a constant curvature and a lower section having an arch and a different curvature than the constant curvature of the upper section, being adapted for ground support, and four straight tubular frames made of one of composite fibers and a metal alloy for supporting an inner floor slab, wherein the tubular ovoid frames and the straight tubular frames form a first module of the modular adaptable housing architecture, wherein the straight tubular frames are designed to facilitate attachment between at least two modules, wherein the first module is formed by crossing the two tubular ovoid frames to create a variable angle at the ends of lower orthogonal axes and at the four straight frames which are coplanar in a horizontal plane of the oval cross-sectional housing body, wherein two of the straight tubular frames are crossed and inserted between the upper sections with an elliptical arc of each tubular ovoid frame, wherein two of the straight tubular frames are parallel and located between the ends of the crossed straight tubular frames and are adapted to be linked to a second module by inserting straight tubular frames between upper nodes and lower nodes at the cross-arranged ovoid frames and straight frames, and wherein joints between the ovoid and straight frames are resolved by rotational mechanical articulation. an oval-cross-section housing body having: two tubular ovoid frames made of one of composite fibers and a metal alloy, wherein the tubular ovoid frames act as ribs of the oval cross-section housing body, and wherein the tubular ovoid frames have an upper section with an elliptical arc having a constant curvature and a lower section having an arch and a different curvature than the constant curvature of the upper section, being adapted for ground support, and four straight tubular frames made of one of composite fibers and a metal alloy for supporting an inner floor slab, two tubular ovoid frames made of one of composite fibers and a metal alloy, wherein the tubular ovoid frames act as ribs of the oval cross-section housing body, and wherein the tubular ovoid frames have an upper section with an elliptical arc having a constant curvature and a lower section having an arch and a different curvature than the constant curvature of the upper section, being adapted for ground support, and four straight tubular frames made of one of composite fibers and a metal alloy for supporting an inner floor slab, wherein the tubular ovoid frames and the straight tubular frames form a first module of the modular adaptable housing architecture, wherein the straight tubular frames are designed to facilitate attachment between at least two modules, wherein the first module is formed by crossing the two tubular ovoid frames to create a variable angle at the ends of lower orthogonal axes and at the four straight frames which are coplanar in a horizontal plane of the oval cross-sectional housing body, wherein two of the straight tubular frames are crossed and inserted between the upper sections with an elliptical arc of each tubular ovoid frame, wherein two of the straight tubular frames are parallel and located between the ends of the crossed straight tubular frames and are adapted to be linked to a second module by inserting straight tubular frames between upper nodes and lower nodes at the cross-arranged ovoid frames and straight frames, and wherein joints between the ovoid and straight frames are resolved by rotational mechanical articulation.
