Covering Boston
Boston is about 27 miles south-east of Lincoln. We also cover Spalding (14 miles to the south), Skegness and Wisbech.
Homes in the East Midlands
The East Midlands combines red-brick terraces in the cities with a lot of post-war and modern estate housing, so rear extensions, garage conversions and loft conversions are all common.
What do you get with a basement conversion?
A basement conversion turns an existing cellar into dry, usable rooms, or excavates a new basement under a house. Converting an existing cellar is far simpler and cheaper than digging a new one, and often does not need planning permission.
- Damp and structural survey
- Underpinning or lowering the floor where needed
- Finished floors, walls and ceilings

How is a basement conversion approved in Boston?
English projects need planning clearance from the local council, building regulations sign-off from building control, and party wall notices where the work is on or near a shared boundary. We prepare and manage all three.
Converting an existing cellar with no external changes usually does not need planning permission in England.
What should Boston homeowners check first?
- Groundwater levels drive the waterproofing design and cost.
- A pump for the drainage system needs a battery back-up.

Your questions answered
Does a cellar conversion need planning permission?
Usually not if nothing changes outside. New basements and lightwells often do.
