Work is moving along at One Wall Street, the largest office-to-condominium conversion project in New York City real estate history. The Financial District building has been steadily making progress with its interior makeovers, including the soaring oxblood and orange-colored walls and ceilings of the historic Red Room. Meanwhile, the glass curtain wall for the retail addition on the lower levels, as well as the multi-story addition atop the mid-century annex are becoming more prominent. SLCE Architects is the architect of record, and Macklowe Properties is the developer of the $1.5 billion project. CORE is handling sales and marketing of the planned 566 residential units.
