Between Housing Demand and Environmental Goals: Alejandro Aravena on Incremental Solutions and Net-Zero Concrete

During the Time Space Existence exhibition, organized by the European Cultural Centre in Venice, Pritzker Prize-winning architect Alejandro Aravena and his firm ELEMENTAL unveiled a full-scale prototype for a new approach in incremental housing solutions. Titled the USB Core, standing for Basic Services Unit housing prototype, this proposal aims to demonstrate how efficient construction can provide all the essential housing components in a minimal space. The prototype is also the result of a collaboration between the architecture office and concrete manufacturer and researcher Holcim, and is built out of a newly developed type of net-zero concrete mix. It also incorporates fully recycled aggregates, in alignment with circular economy principles. The collaboration aims to demonstrate a more environmentally conscious yet cost-effective way of providing essential services to at-risk communities without harming the planet.

While on site in Venice, ArchDaily's managing editor Maria-Cristina Florian had the chance to sit down with Alejandro Aravena and discuss the implications of this collaboration, the urgent need for housing, and the role of the architect as the coordinator of a process involving many actors.
