We currently have a 1930s build with a lean to on the semi side. The pros: the cat litter box lives there, muddy garden shoes, light gardening things and occasional seedlings live there. Other things live there but we’d be happy to find them new areas in the house, these are the things that we’d miss. So has anyone built an extension with a glass box on the corner which isn’t a conservatory but more winter garden ie no heating with a modern extension would it work etc? Any thoughts
