Bungalow rear extension in Exeter
Single-storey rear extensions that keep everything on one level. We design, get the approvals for and build rear extensions for bungalows in Exeter and the surrounding area, with one contract from the first survey to building control sign-off.
Exeter is covered from our Devon round, including EX1, EX2, EX3 and EX4. For Exeter 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 Exeter?
In Exeter, our guide for a bungalow rear extension is £1,920–£3,120 per square metre including VAT for a standard specification. South West prices run slightly above our West Midlands baseline; natural stone to match the house is the main variable.
| Size | Guide price inc VAT |
|---|---|
| 3 m wide × 4 m deep (12 m²) | £23,000–£37,500 |
| 4 m wide × 6 m deep (24 m²) | £46,000–£75,000 |
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 Exeter?
Planning for a bungalow rear extension in Exeter follows the English householder rules.
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.
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 Exeter like to extend?
Exeter has Victorian terraces nearer the centre and post-war semis on the edges. Sloping gardens are frequent, which affects floor levels and steps down to the patio.
