Now, I'm not sure how treehouses = art, but what I do know is that, come spring and summer months, those treehouses could fetch quite a premium rent. Throw a rope ladder out the door and you've got yourself quite a little financial investment there.
I mean, really! They look like pretty spacious studios for Midtown and they're in a great location. Park views, right across from the Flatiron building, no upstairs neighbors, a little private deck...I bet they could even have pets there!
I like to think of them as the new "it" summer places for all those investment bankers who can't afford the Hamptons this year.
