Two-storey rear extension in Bowthorpe
We plan and build two-storey rear extensions for homeowners in Bowthorpe. A larger kitchen downstairs and an extra bedroom or bathroom upstairs, under one roof. Start with a free site visit, then a written price once the design is agreed.
We cover Bowthorpe (NR4, NR5 and NR8) as part of our Norfolk work. Two-storey rear extensions suit semi-detached houses in Bowthorpe best, where the extra bedroom matters as much as the bigger kitchen.

How much does a two-storey rear extension cost in Bowthorpe?
A two-storey rear extension in Bowthorpe is priced at £1,910–£2,860 per square metre including VAT as a guide, before kitchen fit-out and fees. East of England prices run slightly above our West Midlands baseline; clay soils near trees are the main foundation variable.

These are guide ranges; the written quote after the survey is the figure that counts.
Do you need planning permission for a two-storey rear extension in Bowthorpe?
Whether your two-storey rear extension in Bowthorpe 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 Bowthorpe like to extend?
Bowthorpe mixes Victorian terraces with 1930s semis, so both side returns and full-width kitchen extensions suit houses here.

FAQ
Two-storey rear extension questions in Bowthorpe
Do I need planning permission for a rear extension in Bowthorpe?
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.
Can you match the brick or stone on my Bowthorpe house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
What is the 45-degree rule?
Many councils check that a two-storey extension does not cross a 45-degree line drawn from the nearest habitable window of the neighbouring house. We test it at the first drawing.
Do you handle building control in Bowthorpe?
Yes. We apply to the council or a registered building control approver and hand over the completion certificate.
Do I need a party wall agreement?
In England, usually yes if the extension is on or near a shared boundary or the foundations are close to a neighbour's building. We serve the notices.
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.
