We want ac in orangery which is a kitchen (9x5m) standard height but 3 mostly glass walls and 3 roof lanterns, and 1-second storey bedroom 7x4m, 3.2m height. Single unit supply both rooms should be viable as a unit could sit on orangery roof and feed into the bedroom easily. No access issues plus the bedroom is under major renovation so perfect time to do the work. Any questions please give me a call. Andy
