Do you need planning permission for a wraparound extension in Milford Haven?
Whether your wraparound extension in Milford Haven needs a planning application depends on its size, your house and any local restrictions.
In Wales a single-storey side extension can be permitted development if it is no more than 4 metres high and the house ends up no more than 50% wider than the original. Many side return infills on terraced streets, and most wraparounds, go through a householder application.
The Party Wall etc. Act 1996 also applies in Wales: two months' notice for work to a shared wall and one month for foundations dug close to a neighbour's building.
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?
Older terraces near the centre and post-war semis further out are typical of Milford Haven. Sloping sites are common in Wales, so floor levels and retaining walls are designed at the start.

FAQ
Wraparound extension questions in Milford Haven
Who will build my extension?
Vetted building teams working under contract to us. Your contract is with S&K Property Investments and Improvement Ltd for the design and the build.
Do I need a party wall agreement?
In Wales, usually yes if the extension is on or near a shared boundary or close to a neighbour's foundations. We serve the notices.
Is it worth it over a side return alone?
If you want a dining table and a sofa as well as the kitchen, usually yes.
How much does a wraparound extension cost in Milford Haven?
As a guide, £2,050–£3,350 per square metre including VAT for a standard specification. For example, L-shaped, about 22 m² of new floor: about £45,000–£73,500 at that rate. Your written price follows the survey.
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.
Can you match the brick or stone on my Milford Haven house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
