Do you need planning permission for a single-storey rear extension in Fleetwood?
Whether your single-storey rear extension in Fleetwood needs a planning application depends on its size, your house and any local restrictions.
English permitted development (Class A) allows a single-storey rear extension of 3 metres on a terraced or semi-detached house and 4 metres on a detached one, measured from the original house, with a maximum height of 4 metres and eaves of no more than 3 metres within 2 metres of a boundary.
England also has the larger home extension route: a single-storey rear extension of up to 6 metres on an attached house or 8 metres on a detached house, after prior approval from the council. The council notifies your neighbours and has 42 days to decide; the fee is £249 (£310 for applications made from 8 December 2026). The route is not available on designated land such as conservation areas.
Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent. Before any drawing we look up the property's history with the council, because earlier extensions and removed rights change the answer.
What are homes in Fleetwood like to extend?
Stone and brick terraces are common around Fleetwood. Where houses back onto a ginnel or alley, deliveries can come in from the rear, which makes the build tidier.

FAQ
Single-storey rear extension questions in Fleetwood
What postcode areas do you cover around Fleetwood?
Including FY5 and FY7, and the surrounding Lancashire area.
Do you handle building control in Fleetwood?
Yes. We apply to the council or a registered building control approver and hand over the completion certificate.
Is a flat roof or a pitched roof better?
A warm flat roof keeps the extension low under first-floor windows and suits a roof lantern; a pitched or lean-to roof gives a vaulted ceiling. Both last for decades when built properly.
Do I need planning permission for a rear extension in Fleetwood?
Often not for a single-storey rear extension of up to 3 metres (4 metres on a detached house) under permitted development, or up to 6 or 8 metres with prior approval, unless the house is in a conservation area or its rights have been removed.
How much does a single-storey rear extension cost in Fleetwood?
As a guide, £1,790–£2,910 per square metre including VAT for a standard specification. For example, 3 m wide × 4 m deep (12 m²): about £21,500–£35,000 at that rate. Your written price follows the survey.
Can you match the brick or stone on my Fleetwood house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
