Construction is complete on the Warren Street Hotel, an 11-story building that celebrated its grand opening yesterday at 86 Warren Street in Tribeca. Designed by Paul Taylor with Stonehill Taylor and developed by Firmdale on a land lease from Solil Management, the 135-foot-tall structure spans 44,000 square feet and yields 69 guest rooms operated by Firmdale Hotels, as well as the 150-seat Warren Bar and Restaurant, a drawing room, an orangery, and a private event space. Pavarini McGovern was the general contractor and Kit Kemp was the interior designer for the ground-up project, which stands on the former site of an open-air parking lot between Greenwich Street and West Broadway.
