What's your family set up? No good with small kids, you'd have to be outside all the time as the only enclosed bit you can see from inside rooms is that tiny back yard.
I don't think you'd ever really use the rest of it, it's on the side and accessed by steps so not sure I'd be bothered to cart all my gear outside every time and feels a bit weird sitting exposed on the side.
Inside, upstairs is lovely, downstairs the kitchen area is a mish mash of small rooms and plastic roofs, not sure how warm and steamy it will get in winter?
Pretty but not very practical I would say
