Timber framed very well insulated house, multifuel stove, solar panels. There's no way on earth I would ever want to live in a badly insulated, damp house again.
Stone cottage? No thanks. Lived in a couple of those and they are hugely inefficient to heat.
Especially when some wally wants exposed stone on the inside so it can't have decent insulated walls.
Cob built? Hell no, they are even worse.
Barn conversions are some of the worst houses out there for retaining the heat you throw into them.
Massive shed space, enough woodland to supply wood for the fire. Good amount of space to grow vegetables and a decent orchard.
Decent workshop for my motorbikes and chainsaws and whatever else. Maybe a lift or just a pit so I can work under the van.
Poultry maybe.
After living on a hillfarm when I was younger there's no way I want livestock and would far rather go out to work doing what I do now (carpenter) than trying to make ends meet farming beefstock or sheep.
I've also spend quite enough of my time trying to help pregnant animals deliver to know I don't want any more of that either thank you very much.
I like getting out and about so apart from free heat fuel I'm not so keen on the staying on the land every day knitting my own socks part.
