Kitchen-diner rear extension in Speke
We plan and build kitchen-diner rear extensions for homeowners in Speke. 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.
Speke and its postcode districts L19, L24 and L25 are part of our Merseyside coverage. For Speke kitchens we plan the extraction route and the island drainage before the slab is poured, so nothing has to be chased in later.

| 4 m wide × 5 m deep (20 m²) | £35,500–£58,500 |

Your written price follows a measured survey and an agreed design, so it reflects your house, not an average.
Do you need planning permission for a kitchen-diner rear extension in Speke?
Here is how the rules in England apply to a kitchen-diner rear extension in Speke.
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. 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 Speke like to extend?
Speke 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.
