What occupies this position determines how the surrounding spaces are arranged, connected, and used. Their argument suggests that a center matters not because it occupies the geometric middle, but because the surrounding rooms, paths, and activities give it spatial weight. The projects included here extend that idea beyond communal space, showing how the center can organize circulation, collective use, environmental systems, and the relationship between architecture and what already exists on the site.
