Escher Tower

 — Above a certain height, the primary structural challenge of a tower shifts from gravity loads to wind loads, from vertical to horizontal stress.

 — As a result, most skyscrapers are built like thick columns providing an equivalent foothold to a given wind load, square plans with deep spaces.

 — BIG was asked to design a Scandinavian skyscraper with views and daylight in abundance.

 — BIG designed a structurally complex yet visually simple volume which would appear as an unstable monolith due to the windloads and the tower's minimal foothold.

 — In response, BIG devised a tower that consists of 3 square towers merged into one.

 — The resulting shape acquires a series of distinct silhouettes depending on the position of the viewer.
