Rear extension plans and planning applications in Worcestershire
Measured survey, design options, planning drawings and the application, handled for you. We design and build rear extensions across Worcestershire, from Worcester and Redditch to Kidderminster, covering single-storey kitchen extensions, two-storey additions, side returns and wraparounds.

Planning applications in Worcester go to the local planning authority, and we check its local design guidance for rear extensions before drawing. Worcestershire has a lot of post-war semis and estate houses with long gardens and side access, which makes rear extensions quicker to build.
What does it cost in Worcestershire?
As a guide, £1,000–£2,500 including VAT. We put a fixed price in writing once the design is agreed, and explain any provisional sums such as foundations.
Do you need planning permission in Worcestershire?
A two-storey rear extension can be permitted development in England only if it projects no more than 3 metres, stays at least 7 metres from the rear boundary, matches the existing roof pitch and has obscure-glazed upper side windows. In practice most double-storey rear extensions go through a householder planning application.
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.
