A gym that wears its structure like a dare—masts and cables doing the work so the inside can breathe.
Sports complex at University of Chicago, U.S.
Visitor Guide
If you can’t get in, don’t leave: the exterior is the lesson. Walk the corner of Ellis Ave & 55th St and track the cable geometry from mast to roof edge.
Sidewalk at Ellis Ave & E 55th St (southwest corner), angled to include masts and the S-shaped roof; late afternoon for dramatic cable shadows.
Primarily for University of Chicago community and members; public access depends on policies and passes. Exterior viewing is always possible from public sidewalks.
It’s essentially a suspension/cable-stayed roof argument disguised as an athletics facility—structure as the primary architectural expression.
30–60 min (exterior + possible quick interior)
Design & Structure
Structure-led design: external mast-and-cable supports suspend the roof, eliminating interior obstructions and turning engineering into the building’s visual identity.
Glass curtain walls and steel masts/cables: transparency to show the structure; steel to make the roof float with minimal interior compromise.
An asymmetrically supported, cable-stayed roof system with masts and counterweights—large open spans achieved by moving support outside the volume.
