House extension drawings in Ealing
Ealing granted 87% of its 946 householder applications in the four quarters to 2026 Q2 (our analysis of MHCLG planning application statistics, table PS2), yet only 20% of its larger home extension prior approvals over eight quarters. The route you choose matters. Our rear extension drawings start from £695.

Two routes, two very different results
A householder application is the ordinary planning route, and Ealing decided 96% of those outside prior approvals within 8 weeks (our analysis of MHCLG planning application statistics, table PS2). The larger home extension prior approval is a notification route for deep rear extensions. Ealing determined 193 of those over the eight quarters from 2024 Q3 to 2026 Q2 and granted 20% (our analysis of MHCLG planning application statistics, table PS1).
The two numbers are not like for like, because the cases differ. They do explain why we do not default to the longest depth the rules allow.
Deciding how deep to go
On a house that is not detached, permitted development lets a single-storey rear extension reach 3 metres beyond the original rear wall, and the prior approval route extends that to 6 metres (GPDO 2015, Schedule 2, Part 1, Class A). Between those two depths the council examines how the extension affects the neighbours, so the position of their windows and the height at the boundary decide how it goes.
If you want 6 metres, read our prior approval guide first. If you can live with a little less, 3 metres is the simpler route and our permitted development glossary entry explains the limits.

Appeals and conservation areas
An Ealing refusal is sometimes overturned: 43% of the 205 householder appeals the Planning Inspectorate decided for the borough between 2021 and 2026 were allowed (our analysis of the Planning Inspectorate Casework Database, release 2609). It is a record, not a forecast.
The national register holds 31 conservation-area entries for Ealing (our analysis of the MHCLG Planning Data Platform conservation-area dataset). Check the council's conservation area map for your road, because the 6 metre route does not apply inside one.
Fees and what to read next
Ealing's fee for a householder application is £548 from 1 April 2026. Our starting fixed fee for single-storey rear extension drawings is £695, and the pricing page lists the others.
For the planning side, see planning permission in Ealing. Once the design is settled, building regulations drawings in Ealing cover the construction stage, and the West Ealing floor plans are useful when you are still working out the layout.
