Straddle3 product offering
Product offeringCore offering
Straddle3 is an architecture collective that designs and delivers participatory, modular, and affordable housing and public-space solutions through open-source methodologies such as ATRI and WikiHousing. Its practice combines tactical urbanism, citizen co-design processes, and prefabricated/modular construction (e.g., APROP, Aligra) to serve public administrations, foundations, and communities. The collective also publishes open-source digital tools and resources for participation in architecture and urban planning.
Product overview
Straddle3 operates as an architecture collective focused on bottom-up architecture with an open-source philosophy. Their portfolio consists of distinct but interconnected products and services: ATRI serves as the core methodology platform for tactical inclusive repopulation, supported by the ATRI Online Platform for case documentation. WikiHousing Barcelona and APROP represent specific housing solutions applying this methodology, while Aligra provides a timber prefabrication system for building renovation. Digital platforms including GRRR (resource reutilization), PublicSpace.tools (public space activation), and Context Weblog (technology culture) enable their participatory approach. Educational tools like Modulark and practical guides support dissemination of their methods, while publications like Wikiplaza Book and Arquitecturas Colectivas Book document their theoretical foundations.
