We're looking at getting a structural glass extension that we can use as an all-year dining room, (will probably have to be structural glass as our house is listed) I've read a few zombie threads about them but was hoping to get some up-to-date info from you lovely mumsnetters on what it's actually like living with one - how expensive are they to keep clean?/what's the temp like?/do you regret getting one or do you love it? Thanks for reading
