Loft Conversions in Kingston upon Thames.
A loft conversion adds a bedroom and bathroom without touching the garden, and in most of Kingston upon Thames it is the most cost-effective way to gain a floor. Which type suits your house depends on the roof: Victorian and Edwardian terraces usually take a rear dormer, 1930s semis with hipped roofs need a hip-to-gable conversion to make the space usable, and in conservation areas a mansard or rooflight scheme may be the only option.
We start by measuring the roof. About 2.2 metres from the top of the joists to the ridge is needed for a comfortable room; we check this at the first visit before anything is drawn. From there our architects design the layout and the stair, our engineers design the new floor and any steelwork, and our team builds it with the house occupied throughout.
Most lofts are permitted development within the 40 or 50 cubic metre allowance, with the dormer at the rear. Flats, listed buildings and streets with Article 4 directions need a planning application, and every loft needs building regulations approval for the structure, fire escape and insulation. We manage all of it.

Kingston upon Thames: the houses and the planning rules.
Kingston combines a historic market town with some of the largest private houses in south-west London on the Coombe estates, where detached houses sit in big gardens on private roads. Between them are Edwardian and inter-war family houses and Victorian terraces closer to the river.
We designed, supplied and fitted a kitchen on Coombe Lane North with high-gloss glass fronts, pine veneer, toughened glass worktops and Gaggenau appliances, a large room in a detached house where the kitchen had to match the scale of the space.
The Coombe Hill, Kingston Old Town and riverside conservation areas cover parts of the borough.
Royal Borough of Kingston
Kingston decides applications. The Coombe conservation areas and private estates have design guidance and covenants that affect extensions and external changes.
Detached houses
Larger plots allow double-storey extensions and basements that would not be possible in inner London, though most need a planning application.
Flood zones
Riverside streets fall within flood zones, which affects basements and ground-floor levels.
