Diggers have now moved on to the Three Mills Green in east London for the £635,000 project.
The site which is having “new life breathed into it” by rejuvenating parks, squares and roads ahead of and beyond the 2012 Games, London Mayor Boris Johnson said.
It is the first phase of the Lea River Park project and part of the London Development Agency’s aim to ensure all Londoners benefit from the London 2012 Games.
This investment in and around the Olympic fringe aims to transform disused public spaces and create more usable green areas.
Three Mills Green is due for completion in spring 2011. It includes an events area, a sculpted viewing terrace, ping pong tables and a petanque court.
New plantings of more than 400 trees, 1,400 shrubs, and 16,000 square metres of wildflower grassland are other key design features.
Johnson said: “For too long this corner of London has been neglected.
“When the world descends on London in 2012, I want to be able to show off the absolute best that this great city has to offer, and our parks, rivers and public squares are an essential part of that plan.”
Derrick Ashley, chairman of Lee Valley Regional Park Authority, said: “Three Mills Green is an invaluable part of Lee Valley Regional Park, an area of public open space for relaxing, walking and cycling in close proximity to Bromley-by-Bow, Stratford High Street and West Ham.
“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.”
