My partner and I are currently renovating an old building, where a run-down conservatory currently joins the main house to the outbuildings. We'd like to replace this with a frameless glass structure. As there's a brick back wall which joins the two buildings, we only need glass for a roof opening of 4m x 2m, and a front opening of 2m x 2m. I'm having trouble finding a company for this at a resonable price. So far I have contacted GlasSpace. Any suggestions gratefully received!
