Two-storey rear extension in Leyton
For homes in Leyton, 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.
We cover Leyton (E10, E11 and E15) as part of our Greater London work. Two-storey rear extensions suit semi-detached houses in Leyton best, where the extra bedroom matters as much as the bigger kitchen.

Do you need planning permission for a two-storey rear extension in Leyton?
Whether your two-storey rear extension in Leyton needs a planning application depends on its size, your house and any local restrictions.
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. At the first visit we measure what is there now and tell you which route fits: permitted development, prior approval or a planning application.
What are homes in Leyton like to extend?
Period terraces in Leyton sit alongside flats, and the difference matters: houses usually keep permitted development rights, while flats and maisonettes need planning permission for any rear extension. In Greater London we check the neighbours' rear windows first, because the upper floor is where most two-storey schemes win or lose planning.

FAQ
Two-storey rear extension questions in Leyton
Do I need planning permission for a rear extension in Leyton?
Often not for a single-storey rear extension of up to 3 metres (4 metres on a detached house) under permitted development, or up to 6 or 8 metres with prior approval, unless the house is in a conservation area or its rights have been removed.
What postcode areas do you cover around Leyton?
Including E10, E11 and E15, and the surrounding Greater London area.
Will we need to move out?
Rarely. The first-floor opening is made late in the job and sealed with temporary screens.
Can you match the brick or stone on my Leyton house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
Do you handle building control in Leyton?
Yes. We apply to the council or a registered building control approver and hand over the completion certificate.
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.
