Loft Conversions in Ruislip.
A loft conversion adds a bedroom and bathroom without touching the garden, and in most of Ruislip 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.

Ruislip: the houses and the planning rules.
Ruislip grew along the Metropolitan line in the 1930s and is still defined by that decade: wide roads of semi-detached and detached houses with hipped roofs, bay windows and long gardens, around a medieval village core with timber-framed cottages and the Manor Farm site. Ruislip Woods and Lido lie to the north.
We fitted out the Masala Chowk restaurant in Ruislip from strip-out to opening, and the surrounding housing is well suited to the rear extensions, hip-to-gable lofts and full refurbishments we carry out across Metroland.
The Ruislip Village conservation area covers the old village; most other streets are unrestricted.
London Borough of Hillingdon
Hillingdon decides applications. Outside the village conservation area, permitted development covers most rear extensions and lofts.
Hipped roofs
Hip-to-gable conversions are the usual way to make a 1930s loft usable, generally within permitted development limits.
Commercial units
Restaurant and shop fit-outs need Hillingdon's consent for shopfront and signage changes and, where cooking is introduced, for extraction.

Is a loft conversion in Ruislip permitted development?
Often, provided the added volume is within 40 cubic metres for a terrace or 50 for other houses and the dormer is at the rear. Flats, listed buildings and streets with Article 4 directions need an application to the London Borough of Hillingdon.
How much headroom do I need for a loft conversion?
About 2.2 metres from the top of the ceiling joists to the ridge. Victorian and Edwardian roofs usually have it; 1930s hipped roofs often need a hip-to-gable conversion to make the space usable. We measure at the first visit.
