Two-storey rear extension in Ilkeston
For homes in Ilkeston, a two-storey rear extension is often the simplest way to gain space without moving. A larger kitchen downstairs and an extra bedroom or bathroom upstairs, under one roof. We take it from survey to completion certificate.
Ilkeston and its postcode districts DE7 and NG10 are part of our Derbyshire coverage. Two-storey rear extensions suit semi-detached houses in Ilkeston best, where the extra bedroom matters as much as the bigger kitchen.

Do you need planning permission for a two-storey rear extension in Ilkeston?
Planning for a two-storey rear extension in Ilkeston follows the English householder rules.
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. 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 Ilkeston like to extend?
Ilkeston has plenty of inter-war semis and bungalows, and single-storey rear extensions suit both.

FAQ
Two-storey rear extension questions in Ilkeston
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.
Can I get a price without a visit?
Our online guide-price tool gives a range in a couple of minutes. A written price needs a survey.
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.
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 the site visit in Ilkeston free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
Do you handle building control in Ilkeston?
Yes. We apply to the council or a registered building control approver and hand over the completion certificate.
