Next to a Grade II* Listed parish church on Bodmin Moor, this new house is the result of extensive dialogue with planners, ecologist, arboriculturalist, a tenacious client and a supportive community. Designed and constructed within the root protection area of the surrounding trees, the house sits on small pad foundations beneath the canopy of a large Sycamore. Reclaimed rag slate roofs and granite rubble stone piers anchor this quietly modern house into its historic context. The builder Tim Whitehead with carpenters Chris Prins and Paul Guard has spent the winter months beneath a scaffold tent carefully constructing the building to the highest environmental and quality standards. They have achieved an air test result of 0.6m3m2hr @ 50Pa which matches the extremely demanding Passivhaus standard. The house is almost entirely constructed of natural cellulose, a renewable resource, with all of the Larch/ Douglas Fir structural timber and cladding boards felled in Cornwall and processed by a saw mill less than 10 miles away. Building fabric U-values (walls, floor and roof) are less than or equal to 0.13W/m2K using a spaced stud/rafter construction. The house has MVHR, an air sealed wood stove, triple glazed windows, optimised passive solar design, solar thermal, and a small gas condensing boiler.
