Kitchen Extension Planning Permission in Bethnal Green

Most single-storey rear kitchen extensions in Bethnal Green fall under permitted development, meaning no full planning application is needed - but the limits are specific, and Bethnal Green's own conservation areas can remove that right entirely on some streets.

Permitted development limits

A single-storey rear extension is commonly allowed up to 3m beyond the rear wall for a terraced or semi-detached house in Bethnal Green, or 4m for a detached one, without needing planning permission. The "larger home extension" prior approval scheme extends those limits to 6m and 8m respectively, but requires notifying neighbours via the London Borough of Tower Hamlets and waiting out an objection period first.

Height limits typically apply too - commonly around 4m maximum for a single-storey rear extension, and no higher than 4m within 2m of a boundary.

What's different in Bethnal Green

the Bethnal Green Gardens and Jesus Hospital Estate conservation areas covering parts of Bethnal Green often means reduced or removed permitted development rights - expect closer attention to matching materials, roofline and window style to the existing house. Check your property's exact status with the London Borough of Tower Hamlets before finalising anything.

Get it confirmed, don't assume it

Even where permitted development likely applies, a Lawful Development Certificate from the London Borough of Tower Hamlets is a formal, low-cost confirmation that protects you if a neighbour complains or you sell the house later. A builder who works regularly in Bethnal Green will usually have a good instinct for whether your plans qualify, but the council's confirmation is what removes doubt entirely.
