Kitchen-diner rear extension in Milford Haven
For homes in Milford Haven, 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 Milford Haven (SA73) as part of our West Wales work. We usually keep the working kitchen where the old one was and put the dining table in the new space by the doors, which suits most Milford Haven homes.

Do you need planning permission for a kitchen-diner rear extension in Milford Haven?
Here is how the rules in Wales apply to a kitchen-diner rear extension in Milford Haven.
In Wales a single-storey rear extension can often be permitted development if it projects no more than 4 metres beyond the rear wall and is no more than 4 metres high. Wales has no prior approval route for deeper extensions, so anything bigger needs a householder planning application.
Conservation areas, National Parks and National Landscapes restrict permitted development in Wales, and listed buildings need listed building consent. At the first visit we measure what is there now and tell you which route fits: permitted development or a householder planning application.
What are homes in Milford Haven like to extend?
Milford Haven has Victorian terraces near the centre and semis further out. Welsh permitted development allows up to 4 metres at the rear for many houses.
