Utility and boot room extensions across Fulham
A utility room extension in Fulham starts with the right design and the right approval route. We take care of both, then build it with our own project management.

Planning rules that apply in Fulham
In England a single-storey rear extension can usually go up to 3 m beyond the original rear wall of a semi-detached or terraced house, or 4 m on a detached house, without a planning application, provided it is no more than 4 m high, keeps eaves to 3 m within 2 m of a boundary and, with other buildings, covers no more than half the land around the original house. The larger home extension prior approval scheme raises those depths to 6 m and 8 m, with neighbours notified and a 42-day decision.
The planning position for a specific Fulham address depends on its history and any designations, which is why we check it at the first visit.
Building regulations approval is separate from planning. In England you can use the council's building control team or a registered building control approver; a full plans application gets the drawings checked before work starts, and the inspector signs the work off with a completion certificate.
Applications are decided by the local planning authority (your district, borough or unitary council).
When a utility room extension makes sense
- Kitchens that have run out of space for appliances
- Busy family homes
- Houses with a side passage or small rear corner
A good utility works like a back-of-house corridor: in from the garden, boots off, coats on hooks, washing on the way through. We plan the door positions so it doesn't become another room to walk around.
Extensions in and around Fulham
Site visits are available across Fulham (SW5, SW6, SW10, W6, W8, W14). Neighbouring towns we cover include Chelsea (1 mile), Putney (2 miles), Battersea (2 miles), Shepherds Bush (2 miles).
Just over the Surrey border, East Molesey is about 9 miles away. London's housing is dominated by Victorian and Edwardian terraces, many with a rear outrigger and a side return, and 1930s semis in the outer boroughs. Conservation areas are common, so the planning check comes first.
