Kitchen Extension Planning Permission in Notting Hill

Whether a kitchen extension in Notting Hill needs planning permission usually comes down to size, not the fact of building one at all - most single-storey rear extensions qualify for permitted development, subject to the limits below and to Notting Hill's own conservation area restrictions.

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 Notting Hill, 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 Royal Borough of Kensington and Chelsea 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 Notting Hill

the Ladbroke and Pembridge conservation areas - the borough has 38 in total, covering over two-thirds of its area covering parts of Notting Hill 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 Royal Borough of Kensington and Chelsea before finalising anything.

Get it confirmed, don't assume it

Even where permitted development likely applies, a Lawful Development Certificate from the Royal Borough of Kensington and Chelsea 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 Notting Hill will usually have a good instinct for whether your plans qualify, but the council's confirmation is what removes doubt entirely.
