I'm considering a house that has an open plan conservatory extension - ie there are no doors between it and the house. I know there are things I need to know and questions I need to ask - probably about building regs - but I'm not sure exactly what these things are! Can anyone tell me, please?
FYI - it's smallish, 3m square, and fully glazed apart from a couple of feet of wall at the bottom on 3 walls. It has French doors out on one side. Its roof is that special plastic instead of glass. Its foundations are unusual, because the garden slopes away from the house, so there's more underground at the back than the front, iyswim...
