B01 Arquitectes

What B01 Arquitectes does

B01 Arquitectes, S.L.P. is a Barcelona-based professional architecture firm constituted in 2001 with roots extending to 1974 through the predecessor practice Amadó-Domènech arquitectes. The firm delivers architecture and urban planning, sustainability and passive design consulting, and rehabilitation/retrofit services, serving public sector clients (municipal governments, universities, cultural foundations) and private developers/corporations across Catalonia and Spain, with selective international projects in the Netherlands and Denmark. Its core technical stack combines heritage rehabilitation expertise with engineered sustainability: computational fluid dynamics, daylight and energy simulation, full BIM (REVIT) modeling with LCA for DGNB certification, and the proprietary DOM prefabrication system using alveolar slabs with integrated radiant floor heating and multifunctional facade panels.

The firm operates on a project-based professional services revenue model, with fees quoted as a percentage of construction cost or fixed fees per project scope, typically on multi-year contract durations. Customer acquisition flows through three channels: competitive public architecture tenders for government work, direct commissions for private developers (e.g., AQ Acentor, EXNOVO, SA Vichy Catalan), and professional network referrals. Notable delivered projects include a 210-dwelling social housing development with DGNB Silver certification (Edifici Londres), a 40,000m² district renewable energy network in Olot, and the award-winning rehabilitation of the Montaner i Simón building for Fundació Tàpies. The four-partner team (Lluís Domènech, Roser Amadó, Sander Laudy, Ramon Domènech) plus newer partner Tomás Guyot and approximately seven additional architects serves an 11-50 employee organization with deep academic and publishing credentials. Revenue is not publicly disclosed, and the firm has not raised institutional funding.
