OFS / Office for SUSTAINABILITY

What OFS / Office for SUSTAINABILITY does

OFS / Office for SUSTAINABILITY is a Spanish professional architecture cooperative founded in 2005 and structured as a Sociedad Cooperativa Profesional, headquartered in Tajonar (Navarra) with additional offices in Madrid and Las Palmas de Gran Canaria. The firm employs nine people and operates as a multi-partner practice whose named architects — including Jorge Javier Aristrain, Diana Aquino, Ekaitz Saez de Okariz, María Sobejano, Iñaki Urquía, and Fermín Olague — are publicly attached to projects. Its core specialisation is sustainable architecture, with technical credentials in PassivHaus (Classic and Plus) certification, nZEB (Nearly Zero Energy Building) design, and industrialized or prefabricated construction systems, including wood-frame housing. The practice has delivered more than 50 projects across sports venues (Navarra Arena, 45,628 m²; El Sadar stadium, 37,460 m²), healthcare (Hospital de Navarra), civic and cultural facilities (Baluarte congress centre, civic centres), and large-scale public and private housing.

The firm's business model is built on winning restricted architectural competitions, primarily for public-sector clients. Revenue is generated through standard Spanish architect fee structures tied to project construction budgets, with project values visible via competition awards ranging from 54-unit social housing developments to 243-unit metropolitan housing portfolios. Primary customers are publicly funded housing agencies (NASUVINSA in Navarra, EMVS in Madrid, EMSV in Getafe), municipal and regional governments (Government of Navarra, Andalucía, Cantabria, País Vasco), and select private developers such as Kategora for coliving and hospitality projects. Since 2014 the firm has maintained a research collaboration with CENER (Centro Nacional de Energías Renovables), co-developing sustainable building methodologies. The cooperative model means equity, governance, and profit distribution are held internally by the working partners, with no external shareholders or venture funding.
