Following the granting of Planning permission by others, Della Valle Architects were commissioned to produce detailed working drawings for thew new eco-dwelling. The construction methods incorporated modern building techniques (Iso quick flooring, ICF Logix walls and SIP's roof panels) to achieve 0.1 U-Values throughout the building, including 0.9 W/m2K triple glazing throughout. Rainwater harvesting and PV panels were also incorporated in the scheme. The dwelling finally achieved an exceptional air test rating of 0.59m3/m2hr@50Pa - exceeding the PASSIVHAUS standard.
