Two-storey rear extension in Widnes
A larger kitchen downstairs and an extra bedroom or bathroom upstairs, under one roof. We design, get the approvals for and build two-storey rear extensions in Widnes and the surrounding area, with one contract from the first survey to building control sign-off.
Widnes and its postcode districts WA7 and WA8 are part of our Cheshire coverage. In Cheshire we check the neighbours' rear windows first, because the upper floor is where most two-storey schemes win or lose planning.

Do you need planning permission for a two-storey rear extension in Widnes?
Here is how the rules in England apply to a two-storey rear extension in Widnes.
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. We check your house's planning history and any conservation area before drawing, so the route is clear before you spend on plans.
What are homes in Widnes like to extend?
Stone and brick terraces are common around Widnes. Where houses back onto a ginnel or alley, deliveries can come in from the rear, which makes the build tidier.
