Guillem Ros Studio is an architecture and interior design practice operating from Barcelona, Spain. The firm specializes in new construction projects and rehabilitation work with a focus on high energy efficiency.
Directed by architect Guillem Ros Maciá, the studio handles projects across multiple disciplines including architecture, urban planning, landscape design, interior design, and building restoration. The practice maintains offices in the Barcelona metropolitan area, specifically in L'Hospitalet de Llobregat.
The studio's approach emphasizes passive climate control systems and integration with existing urban fabric, particularly when working in historic town centers. Their projects demonstrate attention to Mediterranean coastal climate conditions, incorporating intermediate spaces like patios, porches, and terraces that provide both thermal regulation and privacy. The firm favors heavy construction materials for thermal inertia, including exposed concrete, uncoated brick, and wooden frames with natural finishes.
One documented project features a dual-use building combining residential and studio space, achieving remarkably low energy consumption of just 20 kilowatts-hours per square meter annually through passive design strategies. The building employs vertical spatial organization, strategic solar protection using traditional wooden roller blinds, and natural ventilation enhanced by a rooftop solar chimney. Winter heating relies on low-temperature underfloor systems powered by aerothermal technology.
The studio's work reflects contemporary concerns about environmental sustainability while respecting architectural context and material authenticity. Their projects avoid superficial treatments, instead highlighting the inherent qualities of construction materials through minimal intervention.
