Dundon Passivhaus

A family home on the Somerset levels that shows how strong contemporary architecture can work with the local context and the rigours of Passivhaus.

This detached house has a carefully modelled volume that is both efficient and elegant. The construction is entirely from timber save for the insulation which is cellulose. The inside and the outside are lined with UK oak which creates a strong atmosphere. A family of openings have been created to frame views of the landscape beyond. The project was awarded local and national RIBA awards. It came second in the UK Passivhaus awards.
