Extensions in and around Blackwood
Across CF82, NP12, we can visit, measure and advise. The same team covers Gelligaer (2 miles), Risca (6 miles), Caerphilly (6 miles), Pontypridd (7 miles), all within easy reach.
Just over the Gwent border, Pontypool is about 7 miles away. In Wales, terraced houses with rear offshoots are common in the towns, while detached houses and bungalows dominate in rural areas.
Planning rules that apply in Blackwood
In Wales small porches are usually permitted development within size and boundary limits similar to England's. We check the current Welsh limits for your address.
Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.
Building over or within 3 m of a public sewer needs the water company's consent before the foundations go in.
Building regulations approval is separate from planning. Wales has its own building regulations and approved documents; the council or a registered building control approver checks the plans, inspects the work and issues a completion certificate.
Applications are decided by the local planning authority (your county or county borough council, or the national park authority).
Is a porch extension right for your house?
- Busy hallways with no storage
- Homes wanting better kerb appeal
- Front doors that open straight into a living room
Proportion matters on a porch more than on any other extension, because it is at the front. We match the roof pitch and brick and keep the front door in proportion with the house windows.
