Keppie Design's house has traditional external proportions but is re-interpreted internally. The split-level section defines the internal spaces; cellular spaces to the north, larger volumes to the south.
The house has a south-facing garden and protective buffer spaces - a porch to the north elevation and a two-storey sun space to the south. The double-height zone around the main south-facing living area is overlooked by the 'home-work' study space linked to the 'loft' level which incorporates velux windows. A building management system linked to the 'house' computer controls the velux windows while an isdn line allows the house to be used as a base for work. Tenants can separate the ground floor from the upper floors so that either space can be rented out.
Set in a typical row-housing situation with a south-facing aspect, these houses are based on an A-frame structure which is the most efficient and economic method to enclose space. They are entirely prefabricated, with minimal foundation requirements, which means that the on-site construction period is reduced.
The beauty of the A-frame, which is made from webbed and laminated timber, is its simplicity, and when combined with velux Roof Windows the number of spatial permutations is endless.
The houses incorporate grey and rain-water recycling, solar collectors for hot water, and high levels of thermal insulation. The VELUX windows allow passive solar collection.
The roof covering is a metallised single-ply sheet which forms the main external finish.
Internally the finishes are lightweight timber stud partitions with plasterboard.
