I had a cabin (I call it a shed) built 10x12--use it for half fishing stuff and half garden stuff...we had him build a double door to side thinking we'd use it to put lawnmower in but never did. Everyone tells us how cute it is. This same person makes larger ones, I've seen ones he's finished with living quarters in them. They're great sitting next to pond. I'm going to get another one later. Here's his website, the one stained red is mine as I wanted it to match house (picture of mine from this late winter). Metal roof, stained red. Has a porch, windows, etc. Depends what look you're trying to get.
