Set on a site surrounded by mature trees, the client is building a shared home for 2 households. It is to sit lightly on the ground, both in environmental terms and for the construction.
Sitting on steel screw piles, avoiding the tree roots and reducing embodied carbon by eliminating concrete in the build, almost all of the rest of the construction is constructed from timber products. Using a timber frame, insulated with recycled paper and timber insulation boards and timber cladding and decking, this creates a super insulated, cosy home as well as significantly reducing the embodied carbon in the build. The roof and rainwater goods are recyclable zinc. Internally, finishes include timber and clay plasters on fermacell board. Rainwater is collected in recycled whisky barrels for use in the garden. The small amount of space heating required is generated using an air source heat pump. The garden is zoned to enable food to be grown, bathing in the pond and creation of a variety of habitats. Boundary planting will be a hedgerow of edible plants, available to occupants and passers-by. The clients main form of transport is cycling and hence a bike shed replaces a more standard garage.
The house creates light and cosy spaces with areas opening and closing to balance communal living and privacy between the two households living in the home. Views to the treetops from first floor and the garden at ground floor create a calm space, with the atmosphere modulated by the sunlight throughout the day and seasons. The client is a keen cook with the kitchen designed to be a sociable space as well as practical for day-to-day cooking and seasonal preserving.
The new house is also designed to be deconstructed and elements reused at its eventual end of life. The house that was originally on the site was at the end of it’s life, and has been reused in the new build entirely, except for asbestos, plasterboard and some timber. As a wooded site, construction is carefully managed with a tree protection plan. Root protection is also in place which helps to reduce damage to the earth as well as making it a dry and clean site to work on. The gravel used in the root protection has been used around the building and in another KMA project to avoid waste.
