The house is designed to follow the German Passive Haus principles with the primary focus on a high performance external building envelope. Construction methods incorporate high insulation values, reduced thermal bridging, air-tightness and PVC high performance windows. Building systems use two insulation layers targeting Rt5.0 with all internal walls insulated for acoustic comfort. The external walls and roof include an external vapour permeable weather barrier wrap and internal vapour barrier air-tight wrap to providing a high level of air-tightness, targeting 0.6ACH@50pc. To maintain air quality a mechanical ventilation system supplies fresh air to all living areas and extracts stale air from bathrooms using the exhausted warm air to preheat the incoming cold air in winter (HRV – Heat Recovery Ventilation). The wall and roof building systems include a separate zone for services so thermal and air-tight performance is not compromised. The Passive Haus approach guarantees exception comfort, 90% reduction in energy use, acoustically quiet, condensation free, and an healthy indoor environment, proven over 30 years of German development. This house is currently presented at construction so you can view and the inner workings of the Passive Haus approach.

Please note: Opening hours are 10am – 3pm. Gates will close at 3pm.
