Bungalow rear extension in Garston
For homes in Garston, a bungalow rear extension is often the simplest way to gain space without moving. Single-storey rear extensions that keep everything on one level. We take it from survey to completion certificate.
We cover Garston (L18, L19, L24 and L25) as part of our Merseyside work. For Garston bungalows we design the roof first, because the low eaves decide the height of the new room.

How much does a bungalow rear extension cost in Garston?

| Size | Guide price inc VAT |
|---|---|
| 3 m wide × 4 m deep (12 m²) | £21,000–£34,000 |
| 4 m wide × 6 m deep (24 m²) | £41,500–£67,500 |
Your written price follows a measured survey and an agreed design, so it reflects your house, not an average.
Do you need planning permission for a bungalow rear extension in Garston?
Whether your bungalow rear extension in Garston needs a planning application depends on its size, your house and any local restrictions.
Under England's householder permitted development rules you can usually add 3 metres at the back of an attached house, or 4 metres on a detached house, without a planning application, as long as the extension stays under 4 metres high and its eaves stay under 3 metres where it is within 2 metres of a boundary.
If 3 or 4 metres is not enough, England's prior approval route allows 6 metres on a terraced or semi-detached house and 8 metres on a detached house for a single-storey rear extension. Neighbours are consulted, the council decides within 42 days, and the fee is £249, rising to £310 from 8 December 2026.
Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent. At the first visit we measure what is there now and tell you which route fits: permitted development, prior approval or a planning application.
What are homes in Garston like to extend?
Stone and brick terraces are common around Garston. Where houses back onto a ginnel or alley, deliveries can come in from the rear, which makes the build tidier.
