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

Bayswater: the houses and the planning rules.
Bayswater's white stucco terraces and garden squares were built in the mid-nineteenth century to rival Belgravia, and most have since been divided into flats. Behind them lie mews, and along Bayswater Road and Queensway the mansion blocks and hotels. The whole district is a conservation area under Westminster.
We fitted a kitchen here with a metallic red high-gloss island, black tall units and an 80 mm Corian worktop, a good example of how a bold contemporary kitchen can sit inside a stucco building without touching the historic fabric.
The Bayswater Conservation Area covers most of the district.
Westminster City Council
Applications go to Westminster. Conservation-area policies protect the stucco fronts, rear elevations facing squares and the mews.
Converted houses
In converted terraces, changes to shared services, structure and soundproofing between flats need building regulations approval and often a licence to alter.
Basements
Westminster's basement policy applies; light wells and pavement vaults have particular rules.

Is a loft conversion in Bayswater 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 City of Westminster.
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.
