sAtt Arquitectura Triple Balance is an architecture and construction firm headquartered in Madrid, Spain, founded in 2001 by Iñaki Alonso. The organization developed a distinctive approach they term “triple balance,” aiming to integrate social, environmental, and economic considerations in equal measure across all of its work. With a team of 11–50 employees, sAtt is recognized as Spain’s first architecture and construction company to achieve B Corp certification, reflecting verified standards in social and environmental performance.
sAtt’s project portfolio emphasizes sustainable building practices—using ecological materials such as wood and cork, renewable energy systems, and passive design for energy efficiency. Recent projects include the Greenpeace headquarters in Madrid, where strict ecological criteria informed both design and material choices, and “Espacio Triple,” Spain’s first zero CO2 coworking space, which won national awards for sustainable renovation. In 2021, sAtt completed interior and fit-out projects for organizations like Triodos Bank Málaga and Fiare Banca Ética, as well as learning and collaborative spaces for Fundación Tomillo. Other commissions covered the design and fit-out of Vertis Spain’s and Neinver’s Madrid offices.
The firm’s services span initial concept, regulatory management, building execution, and interior design. sAtt is also active in research and development for green construction tools and methodologies, collaborating with communities and launching initiatives such as Distrito Natural, which focuses on co-housing and resilient urban living. This scope places sAtt at the intersection of urban sustainability, technical innovation, and participatory design.
