GFP Real Estate Set to Deliver 3,700 New Housing Units in NYC’s 100 Gold Street Revamp

Key Points

• GFP Real Estate to redevelop 100 Gold Street into 3,700 apartments, replacing a city office building
• At least 25% of units will be permanently affordable
• Includes 40,000 sq ft of public space, a fitness center, and a new senior facility

NYC just handed GFP Real Estate one of the largest housing redevelopment deals on city owned land. The site: 100 Gold Street, a 1960s government office in Lower Manhattan. The plan: 3,700 mixed income units, community amenities, and a new model for how the city uses its real estate.

This project isn’t just another conversion. It’s a signal. The city is turning outdated public assets into high density housing at scale. Here's what’s coming and why it matters to landlords and investors.

Inside the 100 Gold Deal

• The building has housed city agencies since 1993 but rehab costs were too high
• NYCEDC issued an RFP in March 2025, initially targeting 1,000+ units
• GFP’s winning bid triples that. A major density boost in a tight market
