Basement Conversions in Bayswater.
Where a house cannot grow outwards or upwards, it can grow downwards. Many of the older houses in Bayswater already have a cellar or vaults, and converting them into a usable floor is a well-established route to a utility room, guest suite, study or cinema room.
The two things that decide whether a basement works are waterproofing and light. We use a designed system, normally a cavity drainage membrane with a sump and pump, which carries a guarantee, and we bring light in through a lightwell or a rear opening where the site allows. Ceiling height, drainage and structure are all surveyed at the outset.
Converting an existing cellar without changing the exterior of the house does not usually need planning permission. Lightwells, listed buildings and new excavation do, and the central London boroughs have their own basement policies with impact assessments. All basements need building regulations approval and most involve party wall notices, which we prepare and serve.

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.

Basement Conversions in Bayswater: your questions.
Can I convert a cellar in Bayswater?
Usually. Converting an existing cellar without changing the outside of the house does not normally need planning permission. Lightwells, listed buildings and new excavation do, and every basement needs building regulations approval.
How do you keep a converted basement dry?
With a designed waterproofing system, typically a cavity drainage membrane with a sump and pump, or tanking where appropriate. It carries a guarantee and is designed for the ground conditions found on site.
