Intrepid Archtober-ites ventured to the site of the 1964-65 World’s Fair to explore a monument of the Space Age. The New York Hall of Science, a 90-foot-high undulating vertical structure designed by Wallace K. Harrison, was meant to create the illusion of floating in deep space. Cobalt glass shards stud the 5,400 coffers in the rippling wall, filtering sunlight into the interior and bathing it in an intense, blue glow. Ennead Architects associate Theresa O’Leary gave a detailed account of the extensive renovations that were made in preparation for the 50th anniversary of the World’s Fair . Together with Building Conservation Associates, the firm carefully surveyed the entirety of the structure and made repairs to the water-damaged concrete and rusted rebar. Biogrowth and atmospheric soiling, accumulated over the years, were cleaned off. 50 glass panels were replaced. While the renovation of the building is complete, the exterior landscaping is still a work in progress. Due to a history of drainage issues, plans to recreate the original hexagonal pool were scrapped in favor of greenery. Ennead is also working on an outdoor classroom for the school groups that visit the museum. We’ve moved past the Space Race, but the freshly scrubbed Hall of Science stands as a proud testament to its time.
