Bognor Regis, West Sussex
Two-storey rear extension in Bognor Regis
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 Bognor Regis and the surrounding area, with one contract from the first survey to building control sign-off.
We cover Bognor Regis (PO21 and PO22) as part of our West Sussex work. In West Sussex 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 Bognor Regis?
The planning route for a two-storey rear extension in Bognor Regis is set by England's householder rules and your council.
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 Bognor Regis like to extend?
Bognor Regis has a mix of Victorian terraces near the centre and larger Edwardian and inter-war houses further out. Clay soils across much of the South East mean deeper foundations near trees, which we plan for at the survey.

Options and costs
We draw layout options and price each one, so the budget shapes the design rather than surprising you later.
Approvals

Written price, then build
Once the design and approvals are in place, you get a fixed written price and programme, and we build through to sign-off.

FAQ
Two-storey rear extension questions in Bognor Regis
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.
What postcode areas do you cover around Bognor Regis?
Including PO21 and PO22, and the surrounding West Sussex area.
Will we need to move out?
Rarely. The first-floor opening is made late in the job and sealed with temporary screens.

Vetted building teams working under contract to us. Your contract is with S&K Property Investments and Improvement Ltd for the design and the build.
Do you handle building control in Bognor Regis?
Yes. We apply to the council or a registered building control approver and hand over the completion certificate.
Do I need planning permission for a rear extension in Bognor Regis?
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.
