In the post-Covid era, housing faces a necessary and profound redefinition. This project proposes a contemporary reinterpretation of the barn archetype—conceived as a peripheral, versatile, and adaptable structure—capable of responding to multiple ways of inhabiting space. More than a closed typology, it is an open system that challenges traditional housing models.
In light of the obsolescence of “typology” as a design tool, we propose abandoning spatial hierarchies in favor of a modular and flexible language. Housing is no longer a sum of fixed functions, but a field of transformable possibilities, activated by the user. From this perspective, we designed a device that articulates multiple layers of use, capable of evolving over time and adapting to different contexts.
The project is based on a regular structural grid and a low-cost industrial construction system, designed to be prefabricated in a workshop. It uses 140 mm IPN steel profiles with multiple functions: structure (beams and columns), electrical support (for lighting), partition support (using magnetized curtains), and inhabitable complement (to hang hammocks, planters, or other elements). This visible structure becomes a clear, expressive, and functional language.
Movable separation systems are incorporated—curtains suspended by calibrated magnets according to weight and tension—that allow for spatial configuration without perforations. This enables a dynamic and personalized use of the interior, without sacrificing order or material economy.
The housing includes a compact central wet core, above which a loft is developed: an introspective space, windowless, lit indirectly from the lower level, ideal for resting or studying. Not only are square meters optimized, but also cubic meters, generating a three-dimensional occupation of space.
Expansion is anticipated from the outset. South-facing openings, sized like standard doors, allow for the removal of parts of the envelope to continue the growth modulation while preserving the initial architectural language. The system supports various extension options while maintaining the constructive and structural logic of the grid.
Thermal performance is addressed through passive strategies: a north-facing gallery regulates solar radiation, and a thermal trap can be created using movable curtains, enhancing comfort according to the seasons.
This proposal does not present a finished object but an unfinished strategy, open to appropriation, modification, and expansion. We advocate for an architecture with a common, timeless, and universal language, relying on the economy of means as a creative stimulus. Within a restrictive order, maximum spatial flexibility is achieved: a dwelling conceived as a system, not as a product; as a process, not as a typology.
