Questions
Planning and regulations
Does a basement need planning permission?
Converting an existing cellar often does not, but digging a new basement or adding lightwells usually does. Some London boroughs have specific basement policies.
What about my neighbours?
Excavating near a neighbour's foundations normally triggers the Party Wall etc. Act 1996, so notices and sometimes a surveyor's award are needed before work starts.
