Basement Conversions in Fulham.
Where a house cannot grow outwards or upwards, it can grow downwards. Many of the older houses in Fulham 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.

Fulham: the houses and the planning rules.
Fulham is late Victorian family housing on a huge scale: long streets of three-storey terraces built in the 1880s and 1890s, the distinctive Peterborough estate with its stone lions, the larger houses around Parsons Green and the Hurlingham Club, and the new riverside developments along the Thames. Families move here for the houses and then extend them.
Side-return and rear extensions, loft conversions with rear dormers, and basements are the standard sequence for a Fulham terrace, and a full refurbishment often does all three at once. The borough's basement policy and conservation area guidance are well established and we design to them from the outset.
The Parsons Green, Hurlingham, Peterborough Estate, Moore Park and Sands End conservation areas cover most of the residential streets.
London Borough of Hammersmith and Fulham
The borough decides applications. Article 4 directions in most conservation areas mean rear extensions and roof works need a householder application.
Basements
Basements are limited to a single storey and to a proportion of the garden, with a construction method statement and neighbour notification.
Peterborough estate
The Lion houses have specific guidance on roofs, front elevations and rear extensions to keep the estate's uniformity.

Basement Conversions in Fulham: your questions.
Can I convert a cellar in Fulham?
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.
Which parts of Fulham do you cover?
