Two-storey rear extension in Canning Town
For homes in Canning Town, 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.
Canning Town and its postcode districts E13, E14 and E16 are part of our Greater London coverage. Two-storey rear extensions suit semi-detached houses in Canning Town best, where the extra bedroom matters as much as the bigger kitchen.

Do you need planning permission for a two-storey rear extension in Canning Town?
The planning route for a two-storey rear extension in Canning Town is set by England's householder rules and your council.
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. 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 Canning Town like to extend?
Much of Canning Town is Victorian and Edwardian terraced housing with narrow back additions, which suits side returns, wraparounds and 3 metre rear extensions. Many streets are in conservation areas, gardens are short, and almost everything comes through the house or along a rear alley.

Two-storey rear extension questions in Canning Town
Can you match the brick or stone on my Canning Town house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.

Yes for the beam over the new opening and usually the foundations; we arrange them and their calculations go to building control.
