Construction Systems

Our expertise spans traditional house building and modern methods of construction, including Passivhaus eco homes, conservation projects, and urban regeneration. Passivhaus (passive house) refers to buildings designed to stringent energy-efficiency standards, maintaining a nearly constant temperature. These buildings are exceptionally well-constructed, insulated, and ventilated, allowing them to retain heat from the sun and the activities of their occupants, therefore requiring minimal additional heating or cooling.
