Adam America Real Estate and Northlink Capital install helix-shaped grand staircase at The Westly

Manhattan, NY Adam America Real Estate and Northlink Capital, developers of The Westly, a 20-story boutique condo development located at 251 West 91^st St. on the Upper West Side, completed another construction milestone when the helix-shaped grand staircase was installed in the building’s double-height lobby. The grand staircase connects The Westly’s lobby to the second-floor amenity spaces which will include a fitness center and yoga studio; lounge; children’s playroom; youth room for gaming; and music room. The Westly also features a rare rooftop pool with recreational and lounge areas.

The Westly’s grand staircase was installed by lifting four shop fabricated structural mild steel sections each weighing 1,500 pounds, along with nine railing sections, which were then connected on site with A325 structural steel bolts. The pieces were lifted using a two-ton capacity Spyder crane. The Westly’s staircase has a unique, elliptical helix shape, which required complex geometry as the radius is constantly changing throughout its curvature. The team conducted extensive 3D modeling of the shape to achieve precise accuracy. The steel staircase will be cladded with more than 100 custom selected Calacatta Gold Marble pieces from Italy at a later date.

In addition to The Westly’s staircase installation, the building’s limestone façade is also nearing completion. The building is anticipated to be completed this spring.

The Westly features 52 residences consisting of two- to five-bedroom homes, with select homes offering private outdoor terraces. The residences range in size from 1,252 to 3,524 s/f. SERHANT. is handling marketing and sales for The Westly.
