Two new competitions of note explore possible futures for Chicago's public realm. The 2011 Burnham Prize ideas competition sponsored by AIA Chicago and the Chicago Architectural Club calls for new visions for the McCormick Place East building, the 1971 modernist covention center on the lakefront designed by Gene Summers of C.F. Murphy Associates. The massive, Miesian building has a powerful presence on the lakefront, and a vast column-free interior, but parks advocates have long contended it should be removed. Meanwhile, the building's owner, the Metropolitan Pier and Exposition Authority, says it needs $150 million in repairs and is functionally obsolete. The competition aims to inspire new dialogue around the future of the building and site. The Street Furniture 2011 competition sponsored by Architecture for Humanity's Chicago chapter aims for something more universal, new street furniture that could be deployed to activate almost any vacant site. With a $1000 budget in mind, the competition calls for a piece or pieces of street furniture that could activate an open lot for a year in anticipation of future development as a garden. The furniture could then also be moved to a new site. The winning design will be built and installed at an unnamed location.
