Two-storey rear extension in Bourne
We plan and build two-storey rear extensions for homeowners in Bourne. 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 Bourne (PE10) as part of our Lincolnshire work. In Lincolnshire 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 Bourne?
Planning for a two-storey rear extension in Bourne follows the English householder rules.
England's rules allow a rear extension of more than one storey without an application only when it is no deeper than 3 metres and at least 7 metres from the boundary opposite the rear wall, and never on designated land. Most two-storey schemes need householder planning permission.
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 Bourne like to extend?
Red-brick terraces and semis are typical of Bourne. Coal-mining legacy areas in parts of the East Midlands can need a Coal Authority check before foundations are designed.

FAQ
Two-storey rear extension questions in Bourne
Is the site visit in Bourne free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
How long does a rear extension take to build in Bourne?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
Can it be built on a terraced house?
Sometimes, but the upper floor is harder to get through planning on a terrace because of the effect on neighbours. A single-storey extension with a loft conversion is often an easier route.
Do you handle building control in Bourne?
Yes. We apply to the council or a registered building control approver and hand over the completion certificate.
Can I get a price without a visit?
Our online guide-price tool gives a range in a couple of minutes. A written price needs a survey.
Do I need planning permission for a rear extension in Bourne?
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.
