The internationally renowned Royal Institute of British Architects (RIBA) has named the “Modulus Matrix: 85 Social Housing” complex in Cornellà, near Barcelona, as the winner of the RIBA International Prize 2024. The project, designed by Peris + Toral Arquitectes, stands for pioneering approaches in the field of social housing and sets new standards for sustainable and future-oriented architecture.
The Modulus Matrix is a six-storey building with 85 apartments that was developed on behalf of IMPSOL (Metropolitan Institute of Land Development and Property Management). It is characterized by an innovative design with a modular structure. The inspiration for this comes from Japanese architecture and in particular the films of Yasujirō Ozu. The central concept is based on modules of equal size measuring 3.6 x 3.6 meters, which can be flexibly combined with one another.
A key feature of the project is the so-called “democratic room layout”. Living, dining and sleeping areas are designed equally and are not linked by corridors but by direct connections. This allows maximum adaptability of the rooms to the needs of the residents. The position of the kitchen as the central meeting point of the apartment is particularly noteworthy. This design breaks down traditional role models and enhances domestic work.
The apartments also offer dual orientation and cross ventilation, which ensures a pleasant indoor climate. With continuous balconies on the outside and an open gallery overlooking a central courtyard, the design encourages social interaction and a sense of community.
The Modulus Matrix stands out not only for its social vision, but also for its environmentally friendly approach. The use of solid wood significantly reduces CO₂ emissions. In addition, the modular construction concept enables shorter construction times and minimizes the ecological footprint.
The construction without welded joints and with carefully crafted details ensures high building quality. Acoustic and visual privacy were realized through innovative solutions such as mesh partitions and traditional Barcelona shutters.
RIBA President Muyiwa Oki praised the project as a “blueprint for sustainable housing worldwide”. Thanks to its flexible design and the ability to accommodate different family structures, the Modulus Matrix is a pioneering example of architecture that is geared towards people’s needs.
The award jury emphasized the ability to promote a lively community through intelligent room layouts. This redefines classic ideas of family and living.
Architects Marta Peris and José Toral emphasized the positive feedback from the residents. Initially unfamiliar elements such as open kitchens and access via a terrace have proven to be practical and adaptable. This shows that innovative living concepts are not only convincing on paper, but also work in people’s everyday lives.
With its modular design and focus on social and ecological sustainability, the Modulus Matrix provides valuable impetus for the world of architecture. Especially in urban areas with an urgent need for housing, this concept can be implemented quickly and in a way that conserves resources.
The city of Barcelona is already benefiting from similar projects by IMPSOL, which combine public and private funds to realize affordable and social housing models.
The Modulus Matrix is more than just a building – it is a successful example of how architecture can solve social and environmental challenges. Winning the RIBA International Prize 2024 underlines the importance of such visionary projects that put people and the community at the center.
This project is not only an inspiration for architects, but a call to cities worldwide to follow similar paths. Because the future of living starts right here – with innovation, sustainability and a large portion of humanity.
