Two-storey rear extension in Cheltenham

We plan and build two-storey rear extensions for homeowners in Cheltenham. A larger kitchen downstairs and an extra bedroom or bathroom upstairs, under one roof. Start with a free site visit, then a written price once the design is agreed.

Cheltenham and its postcode districts GL50, GL51 and GL53 are part of our Gloucestershire coverage. Two-storey rear extensions suit semi-detached houses in Cheltenham best, where the extra bedroom matters as much as the bigger kitchen.

Do you need planning permission for a two-storey rear extension in Cheltenham?

Planning for a two-storey rear extension in Cheltenham follows the English householder rules.

England's rules allow a rear extension of more than one storey without an application only when it is no deeper than 3 metres and at least 7 metres from the boundary opposite the rear wall, and never on designated land. Most two-storey schemes need householder planning permission.

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 Cheltenham like to extend?

Cheltenham 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.

FAQ

Two-storey rear extension questions in Cheltenham

How much does a two-storey rear extension cost in Cheltenham?

As a guide, £1,870–£2,810 per square metre including VAT for a standard specification. For example, 3 m × 5 m footprint, two floors (30 m²): about £56,000–£84,000 at that rate. Your written price follows the survey.

Will I need a structural engineer?

Yes for the beam over the new opening and usually the foundations; we arrange them and their calculations go to building control.

Is two-storey cheaper per square metre than single-storey?

Usually yes, because the foundations and roof are shared across twice the floor area. The total cost is higher.

Is the site visit in Cheltenham free?

Yes. We visit, measure up and talk through the options with no cost and no obligation.

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.

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.
