For Oxford bungalows we design the roof first, because the low eaves decide the height of the new room. Oxfordshire has a mix of Victorian terraces near the centre and larger Edwardian and inter-war houses further out. Clay soils across much of the South East mean deeper foundations near trees, which we plan for at the survey.

How much does a bungalow rear extension cost in Oxfordshire?

For Oxfordshire we work from the South East England rate: £2,070–£3,360 per square metre of new floor, including VAT, standard specification. South East prices run above our West Midlands baseline, mainly on labour rates and clay-soil foundations.

Do you need planning permission in Oxfordshire?

English permitted development (Class A) allows a single-storey rear extension of 3 metres on a terraced or semi-detached house and 4 metres on a detached one, measured from the original house, with a maximum height of 4 metres and eaves of no more than 3 metres within 2 metres of a boundary.

England also has the larger home extension route: a single-storey rear extension of up to 6 metres on an attached house or 8 metres on a detached house, after prior approval from the council. The council notifies your neighbours and has 42 days to decide; the fee is £249 (£310 for applications made from 8 December 2026). The route is not available on designated land such as conservation areas.

Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent.

FAQ

Questions people ask

Can a bungalow extension be fully accessible?

Yes: level thresholds, wider doors and a wet room are straightforward to design in.

Will the roof look odd?

Not if the pitch and tiles match. Where the eaves are low, a flat-roofed section with a lantern is an alternative.

Can I extend the loft as well?

Sometimes, but that is a different project; a rear extension keeps everything on one level.

Do you cover all of Oxfordshire?

We cover 13 towns and districts in Oxfordshire, including Oxford, Banbury and Abingdon.

Who builds the extension?

Vetted building teams working under contract to us; your contract is with S&K Property Investments and Improvement Ltd.
