Check this cottage. I'm also posting today over at my Thursday guest home, Fred Flare. The architects call it a "deluxe shed". It has everything you need for a little weekend getaway. They kept it pretty raw although they did manage to drop some pretty killer ideas inside.
Here is the loft/bunk area. A sweet take on a stair rail. They went with industrial netting so that if you do jump ship you won't find yourself somewhere on the first floor.
A nice little galley kitchen that opens right up to the outside.
