Ziggy, Flatiron Public Plaza Holiday Design Competition

New York City, NY, USA, 2019

Ziggy was the 2019-2020 Flatiron Public Plaza Holiday Design Competition winner. Designed by the architecture firm Hou de Sousa, Ziggy was fabricated from painted rebar and 27,000 feet of iridescent cord. It creates a fun, colorful, interactive installation at this well-traveled crossroads in New York City, directly across from the famed Flatiron Building and adjacent to Madison Square Park.
schlaich bergermann partner was proud to work with Hou de Sousa by serving as design engineer, consulting on the design, and verifying that Ziggy could withstand environmental and accidental loads while it was up and enjoyed by the public.
Ziggy is formed from a series of 11 frame modules fabricated from #6 and #5 weldable steel reinforcement, connected with bolts and steel cable ties, and secured to the ground with concrete anchors. The primary design requirements were to account for high wind speeds in the area and the possibility of errant climbers.
Ziggy was named the top public art installation of the season by Curbed and quickly established itself as one of New York City's most popular social media attractions.
