And that's how you do a playground hill...more work from Erect Architecture

Other projects by Erect Architecture show some of the best use of topography I've seen anywhere...they recognize the hill as a geometric construct rather than just a pile of dirt; one that creates interesting spaces above, below, and beside, all with potential for play, as well as for loosely defined hang-out spaces loved by teens and tweens.   If you're installing a playground hill, ask yourself what interesting things you could do above, below, and beside it.  Also, note that the hills are steep enough to feel risky, which is vital!  The photos here are from Erect's Evelyn Hill  Park installation in Hackney London, but peruse their website for other inspirational playground topographies.
