Basement and cellar conversions in Bromsgrove

Covering Bromsgrove

We work in Bromsgrove (B61) and the places around it, including Redditch, Droitwich and Bartley Green.

Homes in the West Midlands

Red-brick terraces and inter-war semis make up much of the housing in the West Midlands, which suits rear extensions, dormer lofts and hip-to-gable conversions, with more modern estates on the edges of the towns.

What does a basement conversion involve?

Everything below ground depends on keeping water out. We design the waterproofing system (usually a cavity drain membrane with a pump, or tanking) to the relevant British Standard guidance, then add insulation, ventilation, light and an escape route. New basements involve underpinning and a party wall process and are designed with a structural engineer.

How is a basement conversion approved in Bromsgrove?

In England we deal with the council’s planning team for permission or a lawful development certificate, with building control (the council or a registered building control approver) for inspections, and with neighbours under the Party Wall etc. Act 1996 where it applies.

Converting an existing cellar with no external changes usually does not need planning permission in England. Digging a new basement or adding a lightwell often does, and many councils have basement policies.

What can affect a basement conversion?

Groundwater levels drive the waterproofing design and cost.
A pump for the drainage system needs a battery back-up.
