Perkins Eastman repositioned 180 Maiden Lane, a property in Lower Manhattan that had not been updated since 1980. Because of the departure of a large anchor tenant, our client, SL Green, sought to reimagine the building as a modern and amenity-laden option for new tenants. The enhancements included renovations to the base façade and entrances; revitalization of the 29,000 sf (2,694 sm) privately owned public atrium; and updates to the fitness center, conference center, servery/dining facility, elevator cabs, restrooms, elevator lobbies, and security desk. Our project approach established an organized hierarchy of entrances/façades to transform the entry sequence into a grand arrival experience. The interior public atrium now features cohesive, energized amenities. And to emphasize transparency between the interior and exterior while leveraging the visual and physical connection to the emerging waterfront, we replaced the mirrored glass at the base of the building with high-efficiency clear glass. During the design process, however, Hurricane Sandy hit lower Manhattan and submerged the entire lower level of the plaza and atrium. Due to these events, the scope of renovations was expanded to overhaul the entire building infrastructure, develop a perimeter-hardening program, and modify the planned finishes to include water-resistant finishes in the event of another storm.
