Kitchen Extension Planning Permission in Hull

Most single-storey rear kitchen extensions in Hull fall under permitted development, meaning no full planning application is needed - but the Avenues conservation area and any listed Old Town properties can restrict this further.

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, 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 council and waiting out an objection period first. Height limits also apply - commonly around 4m maximum, and no higher than 4m within 2m of a boundary.

Where it gets more complicated

The Avenues conservation area, covering the city's larger Victorian villas, means materials and roofline visibility get closer scrutiny than a standard permitted development check elsewhere in Hull - worth confirming your property's exact status before finalising a design, particularly if it also carries listed status in the Old Town.

Get it confirmed, don't assume it

A Lawful Development Certificate from Hull City Council 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 your specific part of the city will usually already know whether your street sits inside a conservation area.
