Rear extensions for terraced houses in Gloucestershire
Rear and side return extensions for terraces, with access through the house and two neighbours. Rear extensions in Gloucestershire: we cover 10 towns including Gloucester, Cheltenham and Stroud, with design, approvals and the build under one contract.
On a Gloucester terrace both neighbours usually need party wall notices or agreement, so we talk to them early. Stone-built and rendered houses are common around Gloucestershire, so matching the walling is a design decision in its own right: natural stone, reconstituted stone or a render finish across old and new.
How much does a terraced house rear extension cost in Gloucestershire?
In Gloucestershire, our guide for a terraced house rear extension is £2,130–£3,430 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 × 4.5 m deep (13.5 m²) | £29,000–£46,500 |
| 3 m wide × 6 m deep (18 m²) | £38,500–£62,000 |
Ground conditions, glazing, the roof and how far the house is opened up move the final figure within the range.
Do you need planning permission in Gloucestershire?
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.
The Party Wall etc. Act 1996 applies in England: you serve notice two months before work to a shared wall, and one month before digging foundations within 3 metres (or 6 metres for deeper foundations) of a neighbour's building. Neighbours can agree in writing; if they dissent, surveyors agree an award.
Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent.

FAQ
Questions people ask
Can you build without side access?
Yes. Materials come through the house in protected runs or over the roof by crane on tight sites.
Do both neighbours need party wall notices?
Usually yes in England and Wales, because the extension often sits on or near both boundaries.
How deep can I go on a terrace?
3 metres under permitted development in England, or up to 6 metres with prior approval outside designated land.
Do you cover all of Gloucestershire?
We cover 10 towns and districts in Gloucestershire, including Gloucester, Cheltenham and Stroud.
