Simon Winstanley Architects have another award winning green house to add to their portfolio. The Houl, in southern Scotland, is not only net "zero carbon", but an impressive open-plan modern statement to boot.
The house is sited in a natural concave area of hillside facing principally west along the contours to enjoy the spectacular landscape setting of the river Ken valley and the ridges of the Rhinns of Kells hills opposite.
The intention was to create a contemporary single storey "long house" which is recessive in the landscape, sustainable in its construction, very low in energy consumption, and aiming for zero net emissions of carbon dioxide for all energy use in the house.
The design uses lightweight but highly insulated steel and timber frame construction, clad in cedar weatherboarding allowed to weather to a natural silver grey colour. The roof ﬁnish is pre-weathered grey standing seam zinc. Windows and external doors are triple glazed high performance timber, painted grey. All
insulation levels are to Passiv Haus standards.
The slope of the roof of the main living accommodation follows the slope of the hillside, with the rear roof meeting the main roof at a shallower angle to allow morning sunlight to penetrate the centre of the house.
The entrance to the house is sited on the north east side of the house under the cover of the roof to provide shelter from the prevailing wind. The principal rooms are situated along the contour of the site to enjoy the views across the valley to the west. The ancillary spaces are generally to the rear.
The house is net "zero carbon" by using very high levels of insulation, minimising air inﬁltration heating using an air source heat pump with a "whole house heat recovery ventilation system", and generating electricity using a wind turbine.
