We have developed a house design set within the grounds of an existing house. The site is surrounded on two sides by beautifully mature trees. The north side is flanked by young saplings. We were seeking to maximise the passive solar gain potential for a new dwelling whilst respecting the existing views into and out of the site. The curved roof form has a reduced surface area compared to a conventional form. This in turn reduces energy need by the reduction in heat losses. A slightly elongated solar-oriented form provides the best balance between heat loss and beneficial solar gain. The house has been designed to ensure that there is a sensitive relationship with its surrounding landscape and site constraints. Utilising the change in levels, noise reduction methods, the movement of the sun, its heating influence and site conditions to inform the design. Planning Consent Granted on 11th September 2015
