Rear extension plans and planning applications in Nottinghamshire
Measured survey, design options, planning drawings and the application, handled for you. Rear extensions in Nottinghamshire: we cover 15 towns including Nottingham, Mansfield and Worksop, with design, approvals and the build under one contract.
Planning applications in Nottingham go to the local planning authority, and we check its local design guidance for rear extensions before drawing. Nottinghamshire has plenty of inter-war semis and bungalows, and single-storey rear extensions suit both.
What does it cost in Nottinghamshire?
As a guide, £1,000–£2,500 including VAT. Your written price follows a measured survey and an agreed design, so it reflects your house, not an average.
Do you need planning permission in Nottinghamshire?
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.
