Typical conservatory, only useable a few times a year but it is currently completely unfurnished. We have in the past had sofas and things in there but the dog and the cats sleep out there a lot and drag a lot of crap in from the garden (not to mention fur!).
thought about putting a garden bistro table in there and some plants but it's quite big so not sure how to fill it so it looks like a nice garden room but doesn't have soft furnishing that pets will wreck
