Following the development of the Gomos System prototype and its debut at La Biennale di Venezia, Portuguese firm SUMMARY expanded its prefabricated design principles with the 1000m² Prefabricated Housing project in Vale de Cambra. The scheme unites housing and service functions within a single modular structure that prioritizes speed, affordability, and adaptability. SUMMARY’s use of industrialized building systems allowed the project to be completed with minimal on-site labor, while maintaining architectural quality and spatial flexibility. Conceived as a hybrid between collective housing and individual dwellings, the project reinterprets the potential of prefabrication as an instrument of efficiency and social accessibility. Its straightforward material palette—exposed precast concrete panels—reflects the studio’s ongoing research into resource optimization and the environmental benefits of factory-based construction.

After the success of their modular Gomos System showcased at the Venice Architecture Biennale, SUMMARY studio continued its exploration of prefabricated construction with the 1000m² Prefabricated Housing in Vale de Cambra. The project stands as both a technical and conceptual evolution of the prototype, translating its modular logic into a fully inhabited, mixed-use complex.

From the outset, the client’s demands for a rapid, cost-efficient, and flexible solution guided the architectural approach. SUMMARY’s response was to design a structure composed almost entirely of prefabricated concrete components, reducing both construction time and environmental footprint. The project’s organization is straightforward yet highly efficient: a ground floor accommodates a range of multi-service programs connected to the public realm, while six independent housing units rest above, each measuring 45 square meters.

Taking advantage of the site’s natural slope, the architects created separate accesses for the commercial and residential areas, ensuring autonomy for each function. Although designed as a collective building, the separation between units produces the sense of single-family dwellings, offering privacy, individualized entries, and acoustic isolation. This subtle balance between shared infrastructure and personal space defines the project’s spatial identity.

The ground floor’s structure—formed by prefabricated slabs and external structural panels—was conceived for maximum flexibility. Interior partitions can be reconfigured or removed entirely, allowing users to adapt the layout as needs evolve. This open-ended approach exemplifies SUMMARY’s belief in architecture as an adaptable framework rather than a fixed object.

Throughout the building, exposed precast concrete serves as both structure and finish, eliminating additional cladding or coatings. This choice reflects a deliberate economy of means: fewer materials, reduced labor, and a shorter construction timeline. Every component, produced off-site and assembled on location, fulfills multiple roles—structural support, insulation, and enclosure—thereby demonstrating the practical and aesthetic coherence of industrialized construction.

With 1000m² Prefabricated Housing, SUMMARY reaffirms its commitment to redefining architecture’s relationship with production and efficiency. The project stands as a testament to how prefabrication, often associated with constraint, can yield flexibility, individuality, and a refined architectural expression grounded in simplicity and logic.
