Named Breaker's Yard, the once-derelict scrub land is at Sutton House - a tudor home looked after by the National Trust.
The outdoor space has been transformed into a late-20th century-themed space thanks to funding from Biffa Award and the Mayor of London's Pocket Parks initiative.
The Pocket Parks initiative is creating 100 small green spaces across London.
Breaker's Yard therefore features an edible garden and art installations such as Lobb's The Grange - a 1970s caravan fitted out as an historic stately home - and an ice cream van illustrated by Rose Blake.
The interior of The Grange provides a small, tall space ideal for storytelling while its outside balcony is a great look-out point with a stage for performance pieces.
The House of Fairy Tales charity, which in the past has worked with artists including Steve McQueen, Damon Albarn and Vivienne Westwood, will be using Breaker's Yard to engage families and school children of East London in an interactive learning programme.
The programme is set to include animation, publishing, kinetic sculpture, space opera, cartography, games and tasks.
Breaker's Yard opens to the public from 1pm on August 12, 2014.
