Kitchen-diner rear extension in Haverhill
We plan and build kitchen-diner rear extensions for homeowners in Haverhill. 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 Haverhill (CB9) as part of our Suffolk work. A kitchen-diner is often the reason people in Haverhill extend: the back kitchen in Victorian terraces and 1930s semis is rarely big enough for a table.

Do you need planning permission for a kitchen-diner rear extension in Haverhill?
Here is how the rules in England apply to a kitchen-diner rear extension in Haverhill.
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. At the first visit we measure what is there now and tell you which route fits: permitted development, prior approval or a planning application.
What are homes in Haverhill like to extend?
Haverhill mixes Victorian terraces with 1930s semis, so both side returns and full-width kitchen extensions suit houses here.
