Planning and building regulation drawings in West Ealing (W13)

West Ealing is late-Victorian and Edwardian terraces and semi-detached villas, laid out around Northfield Avenue and the St Stephen's streets, and many have rear gardens that suit an extension. St Stephen's Road, St Stephen's Avenue, Craven Avenue and Cleveland Road are among its streets. For an owner in a terrace or a semi, the options include extending to the back, adding a loft room or reworking the ground floor so the kitchen opens to the garden.

Two conservation areas run into the district, St Stephen's in W13 and Ealing Green, which straddles the W5 boundary. No Article 4 direction covers the W13 conservation areas, but conservation-area status itself takes side extensions, cladding, roof enlargements and rear extensions of more than one storey out of permitted development. A single-storey rear extension within the limits can still be permitted development there, while anything that changes the side or the roof needs an application.

Because the houses are terraced or semi-detached, the neighbours are close. Party walls, daylight and rights of light are real considerations on any extension, quite apart from what Ealing decides. The council's borough-wide Article 4 direction on HMO conversions is a separate matter, but it applies here if you are thinking about letting the house to three or more unrelated sharers. We check the conservation boundary and the party-wall picture against your address before we draw, so you know the route before you pay for a design.

Planning in West Ealing: what to know before you apply

In St Stephen's and Ealing Green, side extensions, cladding and roof enlargements need planning permission because conservation-area status removes those permitted development rights, and front alterations are controlled. Whether a house is inside one of the two areas therefore decides the route, which is why the exact boundary matters. No Article 4 direction covers the W13 conservation areas, but the standard conservation controls still apply, and mature street trees can bring Tree Preservation Order checks to rear works. The borough-wide HMO direction is separate from ordinary extensions. We confirm each of these first and draw to the route that suits the house.

Applications are decided by London Borough of Ealing — its planning pages.

A single-storey rear extension up to 4 m deep on a detached house, or 3 m on any other house, is Class A permitted development subject to the height and materials conditions.
An Article 4 direction applies here and may withdraw this freedom — the schedule must be checked before relying on it.
One or more constraints are unknown — we check the council's registers as part of the free appraisal.
Where permitted development applies, a lawful development certificate proves it for lenders and buyers.

FAQ

West Ealing (W13) — FAQs

Can I build a side extension on my West Ealing house?+

It depends on whether you are inside St Stephen's or Ealing Green. Conservation-area controls restrict side extensions and front alterations, so a house inside one is in a different position from one outside. We check your address and say which route applies.

Do I need to think about my neighbours for a rear extension?+

Yes. On terraces and semis, party walls and daylight or right-of-light questions come up regardless of planning. We raise them early so the design allows for them.
