Do you need planning permission for a bungalow rear extension in Birkenhead?
Planning for a bungalow rear extension in Birkenhead follows the English householder rules.
In England a single-storey rear extension can often be built under permitted development: up to 3 metres beyond the original rear wall of an attached house, or 4 metres on a detached house, no higher than 4 metres, with eaves no higher than 3 metres if any part is 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 Birkenhead like to extend?
Stone and brick terraces are common around Birkenhead. Where houses back onto a ginnel or alley, deliveries can come in from the rear, which makes the build tidier.

FAQ
Bungalow rear extension questions in Birkenhead
Do I need planning permission for a rear extension in Birkenhead?
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 long does a rear extension take to build in Birkenhead?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
Will the roof look odd?
Not if the pitch and tiles match. Where the eaves are low, a flat-roofed section with a lantern is an alternative.
Is the site visit in Birkenhead free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
Who will build my extension?
Vetted building teams working under contract to us. Your contract is with S&K Property Investments and Improvement Ltd for the design and the build.

Yes. We apply to the council or a registered building control approver and hand over the completion certificate.
