This year's finalists, revealed this week, include the Olympic Delivery Authority's inclusive design strategy and Land Securities' Bankside 123 scheme.
St Pancras High Speed 1 Rail Link is up for best built project, while Paddington Central is vying for best built project five years on. Awards will also go to the best new public space, best community-scale scheme, best new place to live and best project to protect communities.
The awards are run by the London mayor, London First and the RTPI with London Councils. Winners will be announced on 24 February. Mayor Boris Johnson said: "The shortlist ranges from modest local schemes that serve their community to the bold projects that will improve our capital for all."
