In London at the moment, so posting some UK-based projects...
This playscape, by Groundwork West London, won both RHS Gold and the BBC Peoples Choice awards at the 2007 Hampton Court Palace Flower Show.
"The joy of designing landscapes, particularly public ones," principal Adam White says, "is you never know who the end user might be – children, teenagers, families, pensioners, office workers, joggers and dog walkers. "
"Groundwork playscape sits somewhere between traditional playground design and the play value of climbing in fallen trees.”The space includes a sculpted landform with tunnels, a climbing structure with poles and nets, an Archimedes screw for water play, scattered climbing boulders, and 'play' plantings: chestnut trees for conkers, daisy lawns for making daisy chains, dandelions for blowing wishes into the wind, and willow for weaving and mazes.
"Playscape" has since been reinstalled in the London borough of Ealing.
