Since 2000, the MoMA and the P.S.1 have been running a competition under their Young Architects Program, each year inviting a group of emerging architects to experiment with new shapes and materials, resulting in a summer installation at the P.S.1. Past winners include WORK ac (P.F.1. Public Farm 1), MOS (Afterparty) and SO-IL (Pole Dance). Architects Newspaper recently announced the short list for the 2011 summer installation, which includes Interboro Partners (NY), FormlessFinder (NY), Matter Architecture Practice (NY) MASS Design Group (Boston) and IJP Corporation Architects (London). Matter Architecture practice was already invited to the 2008 competition, which also happened to MOS back in 2007, then winners in 2009. As usual expect a complete coverage here at ArchDaily, we look forward to see all the projects!
