Hi there, We are in the process of adding a single-storey extension to our house. Both have cavity walls but the builder has used wall plates to connect the two walls without actually opening the existing cavity to make the new and old cavities continuous. No damp-proof membranes appear to have been used either. It does not appear to be required by building regs but is this best/recommended practice? The new walls are now at roof height and the carpenter has already started on the roof rafters. Any advice gratefully received.
Are you a tradesperson and able to answer this question?
