The Undefined Playground

Designed by BUS Architects, the Undefined playground is a modular, portable, and collapsible playground system that can be dropped into an open/public space, transforming it into a play space.

I really love the considerations towards multi-use, and the considerations towards borrowing equipment. I'm curious to know how hard/heavy it is to maneuver, as well as if there is any more seating that gets pulled out.  That would probably be my biggest critique (which is small, at that!).  Great ideas here.

Swarovski Playground

This four-story temple to play in the Austrian mountains, designed by Snohetta, is a collection of interesting spaces for movement and social interaction! Being a large and self-contained facility, it appears that many of the spaces are friendly both to adults and to kids. There are spaces to indulge as well as to spectate--and it seems to operate more like a public space than an exclusive playground.
