Working in Banbury
Site visits are available across Banbury (OX16). Neighbouring towns we cover include Bicester (14 miles), Witney (20 miles), Oxford (22 miles), Carterton (23 miles).
Just over the Northamptonshire border, Brackley is about 9 miles away. Homes across the South East range from Victorian terraces in the older town centres to large detached houses on the edges, so the right extension type varies street by street.
What is included
- Roof design matched to the existing pitch and tiles
- Vaulted ceilings or flat ceilings with storage above
- Lead or proprietary flashings to the main wall
- Roof windows positioned for light and ventilation
- Insulation to current building regulations
Do I need planning permission in Banbury?
In England a single-storey rear extension can usually go up to 3 m beyond the original rear wall of a semi-detached or terraced house, or 4 m on a detached house, without a planning application, provided it is no more than 4 m high, keeps eaves to 3 m within 2 m of a boundary and, with other buildings, covers no more than half the land around the original house. The larger home extension prior approval scheme raises those depths to 6 m and 8 m, with neighbours notified and a 42-day decision.
The planning position for a specific Banbury address depends on its history and any designations, which is why we check it at the first visit.
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).

Your questions about a pitched roof extension in Banbury
Do you cover all of Banbury?
Yes. We cover Banbury and the surrounding parts of Oxfordshire. Site visits are free and there is no obligation.
Will my neighbours in Banbury be involved?
If a planning application or prior approval is needed, the council notifies neighbours. If the work is on or near a shared boundary, party wall notices may also be needed.
How long does a pitched roof extension take to build in Banbury?
On site, typically 10 to 16 weeks once approvals are in place. Before that, allow 6–12 weeks design and approvals.
Is a pitched roof better than a flat roof?
Neither is better in all cases. Pitched roofs blend with traditional houses and shed water quickly; flat roofs give more headroom and suit modern designs and lanterns.
How much does a pitched roof extension cost?
Our guide range is about £2,070 to £3,920 per m² including VAT, a little more than a flat roof because of the roof structure and tiles.
