Hewitt Studios completes £1.5 million eco-house
[FIRST LOOK + PLANS + DATA] Bath-based Hewitt Studios has completed this £1.5 million eco-home in Limpley Stoke
The Code 5, 290m² house sits on a sloping site in an area of outstanding natural beauty on the outskirts of Bath.
Constructed from local stone, the ground floor of the house has been buried into the site to reduce its impact on the landscape of the surrounding area. The upper storeys are more lightweight, constructed from prefabricated timber panels and clad in western red cedar.
The architect’s view
‘The project provides a future model for sustainable and responsible family home; it achieves Code 5 ‘zero-carbon’ energy in use, makes extensive use of local materials and has a low-impact form, one which is respectful of its neighbours and surroundings, whilst allowing its users to enjoy the truly stunning location.
‘In addition, the building has been designed as a demonstration project for best environmental practice - not only for active sustainable technologies, such as the photovoltaic cells and whole-house MVHR system, but for the incorporation of low-energy construction techniques, such as a carbon sequestering CLT structure, straw bale insulation, natural purge ventilation and passive solar control.
‘We have also sought to protect and improve wildlife habitat and site biodiversity. To this end we have installed a biodiverse sedum roof, areas of species rich grassland and planting, a native woodland habitat, an edible herb and vegetable garden, as well as bat and dormouse boxes.’
