What do u all think pls- the House next door sold & massive renovation going on with garage conversation etc. The side wall of the house is what demarcates both houses ( my house and the house under renovation) Now the builder came knocking to say they need access through my side gate into my garden so as to install a vent. I said ok but then I am thinking I should have asked them what type of vent etc. Do I have to say yes as the fumes from the house through the vent is going to come into my own garden/space 🤦🏽♀️🤷🏽♀️I have attached a few pictures to try and show the 2 houses
