Does anyone live on a Grade II listed house? We're moving, and DH has fallen in love with a listed house. Its approx 150-200 years old, original windows which form part of the listing, some original fireplaces etc. I'm a bit worried about the listed nature means, practically. Eg will we be able to double glaze the windows, can we knock through any of the rooms etc. The council haven't been particularly helpful, and the estate agents don't seem to have a clue...
