Rear extension planning drawings in Newcastle upon Tyne

What do rear extension planning drawings cost in Newcastle upon Tyne?

As a guide, £1,000–£2,500 including VAT for a single-storey rear extension, or £2,000–£3,500 for a two-storey scheme. 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. Your written price follows a measured survey and an agreed design, so it reflects your house, not an average.

Do you need planning permission for a rear extension in Newcastle upon Tyne?

Here is how the rules in England apply to a rear extension in Newcastle upon Tyne.

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.

Councils aim to decide householder applications within 8 weeks of validation, and prior approval within 42 days.

Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent. Before any drawing we look up the property's history with the council, because earlier extensions and removed rights change the answer.

What are homes in Newcastle upon Tyne like to extend?

Brick terraces, colliery houses and post-war semis make up much of Newcastle upon Tyne. Former mining areas often need a coal mining risk check before foundations are designed. Planning applications in Newcastle upon Tyne go to the local planning authority covering Newcastle upon Tyne, and we check its local design guidance for rear extensions before drawing.
