The final charcoal-colored curtain wall panels were recently hoisted into place on 130 William Street, the 19th tallest skyscraper under construction in our annual countdown. Designed by David Adjaye of Adjaye Associates, the 800-foot-tall residential building made rapid progress throughout 2019, capped now by the completion of its signature façade of concrete-cast arches. The 66-story Financial District project is being developed by Lightstone, with Hill West Architects as the architect of record. Corcoran Sunshine Marketing Group is handling sales and marketing for the 242 residential units, which will range in price from around $1,300,000 for a one-bedroom to $20,000,000 for a four-bedroom, full-floor penthouse.
