Enforced by referees and court lines, there is technically ‘one’ official game of basketball. Despite these constrictions, the practice of it morphs into individual drills, 1x1s and 3x3s, to rounds of HORSE and Knockout. Like basketball, this seemingly singular fieldhouse gives way to multiple versions of itself – becoming a fieldhouse of fieldhouses – facilitating both the looser, smaller-scale practice to the regulated, team-based game. Each fieldhouse operates independently, but all remain momentarily connected: an open ceiling allowing trash-talk to travel, a center throughline affording glimpses across courts. Users then can experience all types of basketball under one roof.
