Kitchen-diner rear extension in Prenton

We plan and build kitchen-diner rear extensions for homeowners in Prenton. An open-plan kitchen, dining and family room that opens straight onto the garden. Start with a free site visit, then a written price once the design is agreed.

We cover Prenton (CH41, CH42 and CH43) as part of our Merseyside work. For Prenton kitchens we plan the extraction route and the island drainage before the slab is poured, so nothing has to be chased in later.

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

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

English permitted development (Class A) allows a single-storey rear extension of 3 metres on a terraced or semi-detached house and 4 metres on a detached one, measured from the original house, with a maximum height of 4 metres and eaves of no more than 3 metres within 2 metres of a boundary.

If 3 or 4 metres is not enough, England's prior approval route allows 6 metres on a terraced or semi-detached house and 8 metres on a detached house for a single-storey rear extension. Neighbours are consulted, the council decides within 42 days, and the fee is £249, rising to £310 from 8 December 2026.

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 Prenton like to extend?

Prenton has long runs of terraced houses with back yards and alleys, plus 1930s semis further out. Yard extensions on terraces are often single-storey and close to both boundaries.

FAQ

Kitchen-diner rear extension questions in Prenton

Is the site visit in Prenton free?

Yes. We visit, measure up and talk through the options with no cost and no obligation.

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.

Do you fit the kitchen?

Yes, whether you buy it yourself or we supply it. We take the measurements from the built shell, not the drawings.

Who will build my extension?

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 Prenton?

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.
