Planning rules that apply in Prestatyn
In Wales a single-storey rear extension can usually project up to 4 m beyond the rear wall without a planning application, if it is no more than 4 m high, keeps eaves to 3 m and overall height to 4 m within 2 m of a boundary, and covers no more than half the land around the original house. Wales has no larger home extension prior approval scheme.
Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.
The Party Wall etc. Act 1996 applies in Wales as in England: notice must be served before work to a shared wall, building on the boundary, or excavating close to a neighbour's foundations.
Building over or within 3 m of a public sewer needs the water company's consent before the foundations go in.
Applications are decided by the local planning authority (your county or county borough council, or the national park authority).

Included in a typical project
- Lead or proprietary flashings to the main wall
- Roof windows positioned for light and ventilation
- Roof design matched to the existing pitch and tiles
- Insulation to current building regulations
- Vaulted ceilings or flat ceilings with storage above
Matching tiles is harder than it sounds. We source reclaimed or closest-match tiles where the originals are no longer made and agree samples with you before ordering.

Build and sign-off

Questions people ask about pitched roof extensions
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Prestatyn, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Will my neighbours in Prestatyn be involved?
If a planning application is needed, the council notifies neighbours. If the work is on or near a shared boundary, party wall notices may also be needed.
Do you cover all of Prestatyn?
Yes. We cover Prestatyn and the surrounding parts of Clwyd. Site visits are free and there is no obligation.
How much does a pitched roof extension cost?
Our guide range is about £1,720 to £3,260 per m² including VAT, a little more than a flat roof because of the roof structure and tiles.
Can I have a vaulted ceiling?
Yes. A vaulted ceiling with roof windows is one of the main reasons to choose a pitched roof. It needs insulation between and under the rafters to meet the building regulations.
