Two-storey rear extension in Kingswood
Two-storey rear extension in Kingswood: a larger kitchen downstairs and an extra bedroom or bathroom upstairs, under one roof. We measure the house, show you what the rules allow, price it in writing and build it.
We cover Kingswood (BS15 and BS16) as part of our Bristol and South Gloucestershire work. In Bristol and South Gloucestershire we check the neighbours' rear windows first, because the upper floor is where most two-storey schemes win or lose planning.

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 two-storey rear extension in Kingswood?
Planning for a two-storey rear extension in Kingswood 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. 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 Kingswood like to extend?
Kingswood has Victorian terraces nearer the centre and post-war semis on the edges. Sloping gardens are frequent, which affects floor levels and steps down to the patio.
