Ok my question is this:
In England can you have a tradesman ( or woman I guess) come into your home to install an extra toilet and basin, build some studwork and put in a roof window . It would be the fourth loo in the building, and all the others are in good working order.
My DH and I disagree on if this is allowed just now or not. So hoping the Mumsnetter collective can point us in the right direction. (For what it's worth it's me that thinks this breaks the spirit of the rules and therefore could lead us into hot waters with the local authorities.)
Thanks for any input
