Kitchen-diner rear extension in Hythe
For homes in Hythe, a kitchen-diner rear extension is often the simplest way to gain space without moving. An open-plan kitchen, dining and family room that opens straight onto the garden. We take it from survey to completion certificate.
We cover Hythe (SO45) as part of our Hampshire work. For Hythe 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 Hythe?
Here is how the rules in England apply to a kitchen-diner rear extension in Hythe.
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.
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 Hythe like to extend?
Commuter semis and detached houses make up much of Hythe, and longer gardens make England's prior approval route for deeper rear extensions worth considering.

FAQ
Kitchen-diner rear extension questions in Hythe
How much does a kitchen-diner rear extension cost in Hythe?
As a guide, £2,130–£3,470 per square metre including VAT for a standard specification. For example, 3 m wide × 4 m deep (12 m²): about £25,500–£41,500 at that rate. Your written price follows the survey.
Can you match the brick or stone on my Hythe house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
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.
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 Hythe?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
Is the site visit in Hythe free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
