London mayor Ken Livingstone, who runs the awards with London First and the RTPI, announced the winners at a City Hall ceremony this week.
The teams responsible for the city's Olympic bid, including the Joint Planning Authority Team and the London Development Agency, were honoured in two categories, including winning the mayor's award for planning excellence.
They were particularly praised for handling the complex applications to a tight deadline.
London Borough of Newham head of development and building control Vivienne Ramsey picked up the award for best public sector planner or planning organisation. She was commended for successfully balancing community and development needs in one of London's poorest boroughs.
RPS Planning secured the best private sector planner or planning organisation award for its work on a range of schemes including Wembley, Stratford City, the Southall gas works and Brent Cross and Cricklewood.
Bishops Square and Spitalfields jointly won the best built project contributing to London's future award, while Grahame Park Regeneration won the prize for best conceptual project contributing to London's future.
RTPI president Ron Tate said: "The London Planning Awards are an opportunity for the best work of planners to be celebrated with the public."
