Work has begun to transform part of the Lower Lea Valley in preparation for the London 2012 Olympics.
Three Mills Green in east London is being rejuvenated as part of a £635,000 project to make use of disused public spaces.
Work will include creating an events area, a viewing terrace, installing ping pong tables and a petanque court.
It is the first phase of the Lea River Park project and part of the London Development Agency's Olympic legacy.
Derrick Ashley, chairman of Lee Valley Regional Park Authority, said: "We are tremendously excited by the impending changes that the £635,000 funding project allows, transforming Three Mills Island into a significant leisure amenity for existing and future communities throughout the local area and beyond."
The Lea River Park forms the southern end of a corridor of public parkland which will extend 26 miles (42km) from the Lee Valley Regional Park, in Hertfordshire, south to the River Thames at East India Dock Basin.
