fort or art?

As I start craving spring, I start dreading getting the yard back in shape.  I’ve been trying to avoid looking to closely back there.  The kids have already started their fort/tree house campaigning again this year (despite the fact we have not a tree to build one in).  I just feel like, if we build it, they will inevitably grow out of it by the next season.  But I have to admit, when I saw this in the new issue of small, it made me want one, too.
