Arc Architects

This new house in Perthshire was designed to test how green a house can be built within the constraints of low cost housing. Favouring natural local materials over complicated design or sophisticated equipment, a high standard of construction was achieved with low environmental impact.

The house was designed to create a healthy indoor environment, with known asthma and allergy triggers avoided through the passive regulation of relative humidity. The house is also very thermally efficient and makes good use of natural daylight to reduce electrical demand.

The inner walls are built of earth masonry and finished with natural clay plasters in an innovative approach that was monitored as part of a 3-year DTI sponsored research programme.
