How much does a two storey extension cost?

Typically £2,400 to £3,000 per square metre, which usually makes it better value per square metre than a single storey extension of the same footprint.

Are basements viable on chalk?

Often yes, but groundwater and aquifer protection have to be assessed properly. A ground investigation at feasibility stage answers it before money goes into design.

What working in High Wycombe actually involves

High Wycombe and the villages around it, Hughenden, Downley, Penn and Tylers Green, give a wide range of work: extensions and loft conversions in the town, and larger new build and replacement dwelling projects in the surrounding countryside.

The valley setting means level changes, chalk ground conditions and drainage strategy are recurring themes, so we test them before design rather than after.

Planning policy in High Wycombe

The constraints we test before design begins, not after a refusal.

Buckinghamshire Council determines applications, with substantial parts of the district inside the Chilterns National Landscape.
Conservation areas cover parts of the town centre and several surrounding villages.
Green Belt applies to much of the land between settlements, which channels new homes into replacement dwellings.
Chalk geology and aquifer protection influence drainage, soakaways and basement design.
Steeply sloping plots often need retaining structures and a considered access strategy.
