London Borough of Ealing standards at a glance

9 numeric standards taken from London Borough of Ealing's own adopted documents, each shown with the paragraph it comes from. Figures differ between councils — these are this one's.

Rear extension depth

up to 3m

In Ealing, a 3-metre-deep single-storey rear extension is normally fine on an unextended house - deeper needs a detached house or generous gaps to the neighbours. SPD 4 section 5.0

Keep a single-storey rear extension in Ealing to about 3 metres high. SPD 4 section 5.0

Side extension form

at least 1m

at least 1m

Standards are what the council normally expects, not a guarantee. A scheme outside them can still be approved on its merits, and one inside them can still be refused for another reason.

SPD 4 - Residential Extensions

• SPD 4 section 5.0 — Rear extension depth (3 checks) In Ealing, a 3-metre-deep single-storey rear extension is normally fine on an unextended house - deeper needs a detached house or generous gaps to the neighbours. Keep a single-storey rear extension in Ealing to about 3 metres high. Ealing's 3-metre allowance assumes your house has never been extended - if it has, expect the council to look at the total, not just the new bit.
• SPD 4 section 5.0 — Two storey rear Two-storey rear extensions get close scrutiny in Ealing - keep them clearly smaller than the house and away from the fence lines.
• SPD 4 section 4.0 — Side extension form (2 checks) A side extension in Ealing should step back at least 1 metre from the front of the house at upstairs level - in a conservation area, downstairs too. Keep the upstairs of a side extension in Ealing at least 1 metre inside your boundary so the street keeps its gaps between houses.
• SPD 4 sections 5.0 and 12.0 — Heritage constraints In an Ealing conservation area, wrap-around extensions are usually refused, and even a rear extension should not run the full width of the house.
• SPD 4 section 5.0 — Design character Ealing expects extensions to look like part of the original house - matching bricks, tiles and windows that line up.
• SPD 4 section 6.0 — Roof form Dormers in Ealing should sit modestly within the roof, not dominate it - especially in conservation areas.
• SPD 4 Residential Extensions, Garden Space — Amenity neighbouring (2 checks) A smaller Ealing house needs 50 square metres of usable garden left. Adding rooms can tip you into the bigger 75 square metre requirement, so count the rooms you will end up with. A house of five or more habitable rooms needs 75 square metres of garden left in Ealing.
• SPD 4 Residential Extensions, figure 6.2 — Roof alterations (3 checks) Keep the top of the dormer half a metre below the ridge. Keep the dormer half a metre in from each side of the roof. Keep the bottom of the dormer half a metre above the eaves.
