Two-storey rear extension in Lincoln
Two-storey rear extension in Lincoln: 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 Lincoln (LN6) 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 Lincoln?
Here is how the rules in England apply to a two-storey rear extension in Lincoln.
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 Lincoln like to extend?
Lincoln has plenty of inter-war semis and bungalows, and single-storey rear extensions suit both.

FAQ
Two-storey rear extension questions in Lincoln
Do you handle building control in Lincoln?
Yes. We apply to the council or a registered building control approver and hand over the completion certificate.
Can you match the brick or stone on my Lincoln house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
Is two-storey cheaper per square metre than single-storey?
Usually yes, because the foundations and roof are shared across twice the floor area. The total cost is higher.
How much does a two-storey rear extension cost in Lincoln?
As a guide, £1,750–£2,620 per square metre including VAT for a standard specification. For example, 3 m × 5 m footprint, two floors (30 m²): about £52,500–£78,500 at that rate. Your written price follows the survey.
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.
How long does a rear extension take to build in Lincoln?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
