House, Gibson Road, Bristol, England
Private 60 sq m - 2 bedroom one with ensuite, combined living dining kitchen with glazed doors to terrace/conservatory, a utility space is included in the garage.


The house is constructed with dense block walls, insulated cavity and beam and block floors. This provides high thermal mass which combined with good wall, roof and floor insulation, and the under floor heating an efficient means of space heating and comfortable house. 4.5sq metres of solar thermal collectors and 330ltr. dual coil hot water storage combine to produce low energy use, maintenance and running costs. The gas condensing boiler has weather sensing and compensation with high and low temperature take offs for the efficient heating of hot water and space heating. A heat recovery ventilation installation operating at up to 92% efficiency controls humidity and supplies fresh air.

An important feature of the house is the thermal buffer space that protects the double glazed low E end gable from extreme winter low temperatures and at other times also provides useful solar gain. Over heating is controlled by opening the roof and/or windows.

The roof designed by us is motorised and double glazed with low E units. It spans 6 metres with a pin jointed ridge, and weighs 620kg, yet a force of only 18kg will move it. Special bearings have been used, each of which carry force of 400kg.

Published in the April 2006 edition of SelfBuild & Design, the house is also featured in April 2007 edition of the Ideal Home magazine. Commended Award 2005 received from Redland and Cotham Amenity Society.
