Koolhaas's loop — the gravity-defying skyscraper that bends back on itself
Skyscraper.
Featured in OMA's definitive monograph, S,M,L,XL.
Visitor Guide
Walk the full perimeter — the cantilever is best appreciated from the northeast, where the structural impossibility becomes viscerally apparent. The building changes personality from every angle.
From the small park to the northeast for the full loop composition. Dusk with city lights emerging. The low-angle shot from directly beneath the cantilever is vertigo-inducing.
Not open to the public (working CCTV television station). The exterior experience is the point. The surrounding CCTV plaza is accessible.
Arup's engineering uses a diagrid exoskeleton visible on the façade — the diagonal pattern encodes the structural forces. Where the pattern is dense, stresses are high. The building is a structural diagram of itself.

Design & Structure
OMA/Rem Koolhaas with Arup. The irregular diagrid was computationally generated — the steel member density varies with structural demand. Where forces are greatest, the diagrid is densest; where forces are lowest, it opens up. The building reads its own load path.
Structural steel diagrid exoskeleton, glass curtain wall behind. The diagrid is exposed as architectural expression — structural honesty taken to its logical extreme. The two towers lean 6° off vertical.
The 75-meter cantilever connecting the two towers is one of the longest in any building. The diagrid transfers the cantilever loads through the angled towers to the ground — the entire building is one structural system, not two towers with a bridge.
