Rear extension plans and planning applications in Gloucestershire
Measured survey, design options, planning drawings and the application, handled for you. Rear extensions in Gloucestershire: we cover 10 towns including Gloucester, Cheltenham and Stroud, with design, approvals and the build under one contract.
Planning applications in Gloucester go to the local planning authority, and we check its local design guidance for rear extensions before drawing. Gloucestershire 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.
What does it cost in Gloucestershire?
As a guide, £1,000–£2,500 including VAT. These are guide ranges; the written quote after the survey is the figure that counts.
Do you need planning permission in Gloucestershire?
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.
A householder planning application in England costs £548 (£575 for applications made from 8 December 2026), and a lawful development certificate for proposed work costs half the householder fee.
Councils aim to decide householder applications within 8 weeks of validation, and prior approval within 42 days.
