The Delivery of the Olympic Park for the 2012 games marks the first step in the regeneration of the Lea Valley. After the games the Olympic Legacy Masterplan will complete the transformation from an industrial area which formed a spatial barrier between the East and West of London, to a new park bridging the River Lea surrounded by new communities connecting into the existing urban fabric. The Olympic Legacy Masterplan defines the strategic framework by creating a clear rationale for the distribution of building types and density. It describes the adaptation of the pragmatic and functional infrastructure needed for the games into a hierarchy of urban routes knitted into their context, and secondly, by developing a range of building types that respond to the public realm framework and future townscape.
