TIMBER FRAME INSULATION
Insulation levels are high with a combination of natural cellulose insulation and sheep's wool, both of which help the house to breathe and provide a healthy atmosphere. A healthy environment was important and material selection plays a key part here. There are no fitted carpets that harbour dust. The ground floor is floored in natural linoleum and the first floor in engineered oak.
One of the most obvious features are the green roofs over the sitting room and kitchen. Green roofs provide added insulation and attenuate the rate of rainfall run off. Particularly valuable in keeping the building cool in summer, the sedum flowers help to blend the house with the garden.
Heating is provided by a biomass boiler that uses sustainable wood pellets fed automatically from a hopper, providing carbon neutral underfloor heating at a fraction of a the cost of oil. There are also two contemporary wood burner stoves that work alongside the buildings thermal mass continuing the theme design features working together. In the summer hot water comes from an air to water heat pump that takes spare heat from the interior of the house, returning cooled air, this providing free air conditioning. A heat recovery system is linked to the extract system which also has the ability to deliver filtered cool fresh air from the northern side of the building to the first floor.
OAKWRIGHTS BRING IT ALL TOGETHER
A rainwater recovery system provides water for flushing toilets and also naturally soft rainwater for the washing machine.“The walls and the oak frame are clad externally with untreated Siberian larch, a remarkably resilient timber that matches the predicted lifespan of oak and weathers similarly to blend the house into the landscape. The Oakwrights team were instrumental in enabling us to bring all of this together, proving that oak frame can be effectively combined with other techniques to provide an innovative contemporary design. We project managed the scheme ourselves. Having used a prefabricated basement system, we knew that the temporary hard standing was well consolidated before the Oakwrights crane arrived on site. Chappell and Dix were our contractors for the completion of the project after the frame was erected who picked up the project seamlessly from completion of the frame."
