Porch extensions in Christchurch
A porch extension in Christchurch starts with the right design and the right approval route. We take care of both, then build it with our own project management.

Planning rules that apply in Christchurch
In England a porch is usually permitted development if its ground floor area is no more than 3 m² measured externally, no part is over 3 m high, and no part is within 2 m of a boundary next to a road.
In a conservation area, national park, National Landscape, the Broads or a World Heritage Site the permitted development limits are tighter (no side or two-storey extensions without an application). Listed homes need listed building consent, and if permitted development rights have been removed, any extension needs an application.
If the work involves a shared wall, building on the boundary, or digging foundations within 3 m (sometimes 6 m) of a neighbour's building, the Party Wall etc. Act 1996 applies and notice must be served before work starts: two months for work to a party wall, one month for new walls on the boundary and for excavations.
Building regulations approval is separate from planning. In England you can use the council's building control team or a registered building control approver; a full plans application gets the drawings checked before work starts, and the inspector signs the work off with a completion certificate.
Applications are decided by the local planning authority (your district, borough or unitary council).
When a porch extension makes sense
- 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.
Extensions in and around Christchurch
Postcode districts we cover around Christchurch include BH5, BH6, BH7, BH23. Nearby, we also take on projects in Bournemouth (4 miles), Ferndown (7 miles), Poole (9 miles), Wimborne Minster (10 miles).
Just over the Hampshire border, New Milton is about 5 miles away. South West homes range from terraced streets in the cities to stone cottages and bungalows in the countryside, and conservation areas are common in historic centres.
