Manhattan, NY Casoni, the 70-story curvilinear luxury residential tower at 989 Sixth Ave. in Midtown near Bryant Park, has officially topped out at its full 785-ft. height — one month ahead of schedule. The champagne-colored, glass tower is now one step closer to completion, marking a major milestone in the transformation of the Garment District skyline. 

Inspired by the Italian word casone, meaning “grand villas” of timeless style and craftsmanship, Casoni is being developed by Sioni Group in partnership with AB & Sons and designed by C3D Architecture. The building comprises 384,118 s/f with 311 studio to three-bedroom residences, including 284 rentals and 27 condominiums. Leasing and sales are expected to begin in early 2026. 

The glass curtain wall is ascending the tower, giving definition to its signature cylindrical form and champagne-colored façade. Once the construction hoist comes down, installation of the glass at the lower floors will complete the exterior. Rising above Bryant Park and Midtown, the tower’s residences will offer views of the city skyline, the Hudson River, and beyond. 

Inside, residents will have over 25,000 s/f of amenities, including wellness, fitness, social, and entertainment spaces designed for modern luxury living. 

“For our family, this milestone is especially meaningful,” said Jack Yadidi of Sioni Group. “We began in the Garment District more than three decades ago, and now to see Casoni rising here ahead of schedule is a proud moment. The tower will not only stand as an architectural landmark, but also as a reflection of our roots in this neighborhood and our vision for its future.” 

With structure complete, construction will now focus on façade installation, interiors, and amenities in preparation for Casoni’s 2026 debut. REAL New York will serve as the exclusive sales and marketing brokerage.
