Hi,
I have a planning permission for building a semi-detached house beside my detached one.
I would like to build it and living in the two houses joined (by opening two an internal wall).
I do not want to convert the two houses into one as I may sell the two down the line.
Do I need planning permission for opening the link?Is it a non "material" change?
Do you see problems with planning authority, insurance, fire reg., legal, etc.?
Many thanks!
