**Green Street Expands Footprint at 10 Grand Central**
Green Street, a real estate analytics and advisory firm, has doubled its space at 10 Grand Central, a Midtown East office property owned by Marx Realty. The firm, a tenant at the building since 2023, has committed to a new 12,000-square-foot lease. As part of the relocation, Green Street will move its operations from a 5,000-square-foot office on the second floor to a larger space on the 13th floor. The expansion comes amid an ongoing restack at the property.
“As experts in commercial real estate, it’s no surprise that the Green Street team recognizes the value of a workplace that inspires creativity and stimulates collaboration,” said Craig Deitelzweig, President and CEO of Marx Realty. “The one-of-a-kind hotel-like aesthetic at 10 Grand Central delivers an experience unlike any other, and we are always excited to accommodate the growth of our existing tenants while continuing to attract new firms to the building.”
Green Street was represented by Ian Lipman of JLL. Mitchell Konsker, Thomas Schwartz, Carlee Palmer, and Nicole Danyi, also of JLL, represented Marx Realty in the lease transaction.
