Why Do I Need a Party Wall Agreement for My Loft Conversion?

There are several reasons why you might need a party wall agreement for your loft conversion London.

Firstly, if the work involves putting up any new structural support beams or load-bearing walls, then these will need to be built on your side of the boundary line.
