You can extend in Shepherd's Bush, but you will be asking permission for most of it and somebody will be reading the drawings closely. More than 340 listed buildings stand in the streets around it. Over twenty conservation areas fall in the wider area. Three in every four homes are flats. The neighbours keep applying anyway, by the hundred.
Historic England lists 342 buildings in and around the area: 3 at Grade I, 16 at Grade II* and 323 at Grade II. Listing covers the whole building, inside and out, so changes to a listed home need listed building consent on top of any planning permission, and that includes the windows, the staircase and the plasterwork that a surveyor might call tired. Most of the 342 are Grade II, which is the most common grade and still the one that turns a kitchen refit into an application.
The wider box drawn around the area takes in 21 conservation areas. Inside one, the council looks at how a change affects the character of the street, and alterations that need no permission elsewhere, to roofs, front elevations, boundary walls and trees, can need consent. Some of those 21 lie further out towards Acton and Ealing, so whether a particular house is inside one is a question for Hammersmith and Fulham's conservation area maps.
Plenty of people try regardless. Hammersmith and Fulham's planning register holds 1,352 applications for the area between April 2024 and July 2026, and 511 of them came in the last twelve months. That is a lot of loft plans and rear extensions going in front of the same planning officers. Search the register for your own street and the houses either side, because the decisions on next door's identical terrace are the closest thing to a preview of yours.
Then there is the ground. The British Geological Survey puts the area's shrink-swell hazard at class 3, and the whole area reaches that class. Shrink-swell ground swells when wet and shrinks when dry, which moves shallow foundations, so an extension here usually needs deeper footings and a structural engineer's design before a builder quotes. The council and the conservation officer are only part of the planning. The ground needs a say too.
Historic England's Heritage at Risk register includes 11 listed buildings from the same patch. These are buildings in poor condition, where repair may attract grant support and will certainly attract scrutiny. For someone buying an ordinary house nearby they mean little beyond a neighbour with a long-running repair bill.
In practice, the default rules that let a house owner add a modest rear extension or loft dormer without applying apply to houses, and about 74% of the homes on the council-tax list here are flats, which mostly fall outside them. Add a listed building or a conservation area and the default shrinks further. Get the council's view in writing on any specific change, because the builder's view on what counts as permitted does not bind anyone.
Freedom to extend or alter a home is very limited in Shepherd's Bush. Buy the space you need on day one, because adding it later means listed building consent, conservation rules and engineered foundations.
