Condo tower topped out.

Developers Stuart Boesky and Jamison Weiner topped out their mixed-use residential retail condominium development known as 21 East 96th Street.

Marson Contracting Co., Inc., the Construction Manager for the project, poured the 12th and top floor of the 41,000 s/f before a ceremony that took place February 3.

To highlight this milestone, the developers held an impressive ceremony commencing in front of the building where they unveiled the building's structure by lighting it up like the tree in Rockefeller Center.

"We wanted to celebrate this stage in a special way and spared no expense as we have done throughout the entire development of this project," said Jamison Weiner.

At the ceremony Leon D. Marrano III, President of Marson said, "Constructing a building of this size with its many complex and intricate systems at such a busy corner near the entrance to Central Park, is like building the proverbial Swiss watch. It requires extreme dedication of the entire design, construction and ownership team".

The building with a total of nine full-floor homes is located steps from Central Park. Consistent with its historic neighborhood, the design exhibits attention to old-world traditional quality interpreted in a modern format. Construction will be completed this fall.

Guests gathered for a reception at 7 East 95th Street, an 1800s landmark townhouse. As a play on the project's street address "21" East 96th St., the theme for the reception was Black Jack.

Proceeds were donated to the Kellner Family Pediatric Liver Disease Foundation a charity affiliated with Mount Sinai, the community's hospital. The project architect is Manhattan based H. Thomas O'Hara Architect, PLLC.
