When a porch extension makes sense
- Homes wanting better kerb appeal
- Busy hallways with no storage
- 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.
Planning rules that apply in Banbury
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.
Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.
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.
Applications are decided by the local planning authority (your district, borough or unitary council).
Working in Banbury
Postcode districts we cover around Banbury include OX16. The same team covers Bicester (14 miles), Witney (20 miles), Oxford (22 miles), Carterton (23 miles), all within easy reach.
Just over the Northamptonshire border, Brackley is about 9 miles away. The South East has a broad mix of 1930s semis, post-war estates, newer developments and period cottages, and many houses have enough garden for a generous rear extension.

Your questions about a porch extension in Banbury
Do I need building regulations approval in Banbury?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.

Your contract is with S&K Property Investments and Improvement Ltd, which designs and manages the project and the build teams who carry it out.

Our guide range is about £4,450 to £16,800 including VAT, depending on size, materials and whether it includes a WC.
