Kitchen-diner rear extension in Louth

An open-plan kitchen, dining and family room that opens straight onto the garden. We design, get the approvals for and build kitchen-diner rear extensions in Louth and the surrounding area, with one contract from the first survey to building control sign-off.

Louth is covered from our Lincolnshire round, including LN11. We usually keep the working kitchen where the old one was and put the dining table in the new space by the doors, which suits most Louth homes.

Do you need planning permission for a kitchen-diner rear extension in Louth?

Here is how the rules in England apply to a kitchen-diner rear extension in Louth.

In England a single-storey rear extension can often be built under permitted development: up to 3 metres beyond the original rear wall of an attached house, or 4 metres on a detached house, no higher than 4 metres, with eaves no higher than 3 metres if any part is within 2 metres of a boundary.

England also has the larger home extension route: a single-storey rear extension of up to 6 metres on an attached house or 8 metres on a detached house, after prior approval from the council. The council notifies your neighbours and has 42 days to decide; the fee is £249 (£310 for applications made from 8 December 2026). The route is not available on designated land such as conservation areas.

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 Louth like to extend?

Red-brick terraces and semis are typical of Louth. Coal-mining legacy areas in parts of the East Midlands can need a Coal Authority check before foundations are designed.

FAQ

Kitchen-diner rear extension questions in Louth

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 Louth?

Including LN11, and the surrounding Lincolnshire area.

Yes. Wet underfloor heating in the new screed is the usual choice, often with the old room's radiators kept or replaced.

Can you match the brick or stone on my Louth house?

We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.

Yes. We apply to the council or a registered building control approver and hand over the completion certificate.

How long does a rear extension take to build in Louth?

Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
