Kitchen-diner rear extension in Heavitree
For homes in Heavitree, 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.
Heavitree and its postcode districts EX1, EX2 and EX4 are part of our Devon coverage. For Heavitree 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 Heavitree?
The planning route for a kitchen-diner rear extension in Heavitree is set by England's householder rules and your council.
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. 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 Heavitree like to extend?
Stone-built and rendered houses are common around Heavitree, so matching the walling is a design decision in its own right: natural stone, reconstituted stone or a render finish across old and new.

FAQ
Kitchen-diner rear extension questions in Heavitree
What postcode areas do you cover around Heavitree?
Including EX1, EX2 and EX4, and the surrounding Devon area.
Do you handle building control in Heavitree?
Yes. We apply to the council or a registered building control approver and hand over the completion certificate.

Our online guide-price tool gives a range in a couple of minutes. A written price needs a survey.
Is the site visit in Heavitree free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
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.
