Casas Arquicenter designs and builds permanent concrete homes around Passivhaus and nearly zero-energy principles. Buyers can begin with a published house design and modify its plan and finishes, or develop a project from an individual brief.

The advertised turnkey scope includes geotechnical work, architectural and technical services, construction and project direction. The company is suited to buyers seeking a managed low-energy home in Spain, particularly where concrete construction and professional coordination matter more than a transportable unit.
