prepared by Office for Metropolitan Architecture, led by Rem Koolhaas The Stage 2 Public Engagement exercise lasted three months and ran until November 2010. On 4 March 2011, Foster and Partners' plan, City Park, was selected as the master plan out of the three entries. Ronald Arculli, then head of the WKCDA, as well as of the selection board, said the master plan would be submitted to the Town Planning Board at the end of 2011. Construction could start as soon as the fourth quarter of 2012 with the first phase of the WKCD finished by the end of 2015. The plan was originally estimated to cost HK$21.6 billion. In October 2011, the government revised its cost estimates upwards, to over HK$29 billion. The WKCD's Stage 3 Public Engagement Exercise began in September 2011 at the Hong Kong Heritage Discovery Centre. The focal point of the exhibition was a giant 1:250 physical model of the hub. A digital 3D model, photo montages and panels displaying key information and features were also presented. The plan – with public consultation running until 30 October – eventually went to the Town Planning Board, which subsequently gave the go-ahead by the end of next year.

The Bamboo Theatre was initially to be an annual event, but as of 2021 has not been recreated.
