The new addition consists of an open plan dining, living and kitchen with combined scullery and laundry. An alfresco area sits under the main roof with the passageway and bathroom forming the connection to the cottage. Four banks of clerestory windows, half facing north and half to the south, provides an abundance of natural light and airflow into the living spaces.
Passive House Principles have been adopted for the design and construction of the home. German made Kommerling UPVC has been selected for the window frames, and Proclima external and internal wraps to the timber framed wall and roof structure. The result is a high performance and airtight building fabric. Unlike many similar Ecohabit designs, the clients have chosen not to install a Heat Recovery Ventilation system, rather to rely on the abundant natural ventilation the design will experience.
The performance of the existing cottage has been enhanced with new roof cladding, insulation and the sealing up of any existing leaks. A new door separates the old cottage from the new, and without a connecting roof structure the new structure is compartmentalised ensuring performance is not hindered by the old cottage. The old cottage we expect will remain cool in summer but will not retain heat as well as the new extension in winter. The retained rooms of the old cottage are four bedrooms and a bathroom and generally occupants require less heating to these sleeping zones.
