LAOS

What LAOS does

LAOS is an independent architecture and design studio founded in 2018 in Barcelona by architects Xavier Botet and Albert Saboya, operating as a private partnership with no external investors. The studio provides professional architectural services across three core typologies — residential architecture (private reforms and new multi-family construction), public facilities (social centers, schools, housing developments, thermal spas), and building rehabilitation/heritage restoration — supplemented by a specialized Passivhaus design and certification service for which the studio holds certifier homologation. Its underlying technology stack centers on sustainable construction methodology, including Passivhaus energy performance standards, cross-laminated timber (CLT) structural systems, cyclopean stone walls with thermal mass properties, geothermal Canadian well climate systems, and bioclimatic design using natural materials such as lime mortar plasters and bamboo flooring.

The studio generates revenue on a project-fee basis through two channels: direct private commissions (individual homeowners and small developers for residential reforms and new construction) and competitive public tenders (municipal governments, public foundations, and housing development institutes such as BIMSA, Institut Català del Sòl, Ajuntament de Barcelona, and Concello de Bande). LAOS has accumulated 11+ competition wins and award selections since 2015, including first prizes for a 24-unit social housing development, a thermal spa in Ourense, and integral rehabilitations of the Centre Social de Sants and the Muñoz Ramonet Estate in Barcelona. The firm operates across Catalonia and Galicia, Spain, typically via recurring co-authorship partnerships with architects such as Mercè Zazurca, César Sánchez, and Anna Botet for larger public projects, and subcontracts structural and MEP engineering to specialist consultancies (BBG, AGA enginyeria, GP9, TDI, Jordi Payola).

The practice is small and founder-led, with the publicly stated team centered on the two founding partners and a broader network of project collaborators. Pricing is not publicly disclosed and is negotiated per project based on scope, typology, and complexity, consistent with standard Spanish architecture fee structures. LAOS's customer base is a hybrid of public institutional clients (recurring but concentrated in a handful of Catalan/Galician public bodies) and a long tail of private residential clients, with no disclosed revenue figures, no external funding, and no app, API, or digital product surface.
