Bungalow rear extension in Heswall
Single-storey rear extensions that keep everything on one level. We design, get the approvals for and build rear extensions for bungalows in Heswall and the surrounding area, with one contract from the first survey to building control sign-off.
We cover Heswall (CH60 and CH61) as part of our Merseyside work. For Heswall 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 Heswall?
In Heswall, our guide for a bungalow rear extension is £1,740–£2,820 per square metre including VAT for a standard specification. North West prices sit below our West Midlands baseline; access on terraced streets is the main variable.

| 4 m wide × 6 m deep (24 m²) | £41,500–£67,500 |
These are guide ranges; the written quote after the survey is the figure that counts.
Do you need planning permission for a bungalow rear extension in Heswall?
Planning for a bungalow rear extension in Heswall 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.
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. We check your house's planning history and any conservation area before drawing, so the route is clear before you spend on plans.
What are homes in Heswall like to extend?
Stone and brick terraces are common around Heswall. 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 Heswall
Do I need a party wall agreement?
In England, usually yes if the extension is on or near a shared boundary or the foundations are close to a neighbour's building. We serve the notices.
Is the site visit in Heswall free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
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.
Can I get a price without a visit?
Our online guide-price tool gives a range in a couple of minutes. A written price needs a survey.
Can I live at home while the extension is built?
Usually yes. Most of the work is outside until the back wall is opened near the end, and that stage is screened off.
Do you handle building control in Heswall?
Yes. We apply to the council or a registered building control approver and hand over the completion certificate.
