What can be done to weather proof a narrow gap formed where a person is building on his own land alongside the external wall (e.g. an earlier back garden extension built up to the Adjoining Owner?s side of the boundary line?
It is good practice to prevent debris collecting in (or animals entering) the small gap between two adjacent independent structures and the Act allows for any works ?incidental to the connection of a structure with the premises adjoining it?. There are several proprietary products that can effectively seal the gap between two buildings without having to cut into or permanently fix to either building. The Building Owner erecting the second structure would usually carry out this work.
