March 6, 2025 9:00 AM

Newmark secured a 12,103-square-foot lease at 11 East 26th Street, a Class A office asset in Manhattan. The transaction welcomes tenant Reckoner Capital Management, which secured a long-term lease to occupy the entire 10th floor, a brand-new prebuilt space. Newmark Vice Chairman William (Billy) Cohen and Associate Ariel Harwood represented ownership, Rockrose Development (“Rockrose”), while Chairman of National Tenant Representation Neil Goldmacher and Executive Managing Director Josh Friedman represented the tenant.

Doubling-down on its commitment to the office market and the property, Rockrose implemented a robust capital improvement program, totaling over $100 million. The scope of work includes a new rooftop conference and entertainment center, landscaped roof deck with vast 360-degree views, a second-floor amenity club with a lounge, fitness facility, whiskey and wine lockers and multiple high-end full-floor prebuilds, as well as upgraded mechanicals and infrastructure.

“11 East 26th Street sets a new standard for Class A office space in Manhattan’s NoMad submarket, combining state-of-the-art amenities with an iconic location overlooking Madison Square Park,” said Cohen. “Ownership’s significant capital investment and unparalleled views—from the Chrysler Building to One Madison—make it a truly unique offering,” added Harwood.

The property is located between Madison & Fifth Avenues on the northern edge of Madison Square Park, with tenants including Jump Trading and Holocene Advisors, both of which recently expanded in the building. With its seamless access to transportation, dining, luxury hotels and boutique shops, the neighborhood rounds out the workday with energy, ease and historic charm. Four contiguous 31,000-square-foot floors remain available for lease at the property, a rarity for a property of its type in this submarket.

“We’re excited to welcome Reckoner Capital to 11 East 26^th and to continue our tremendous leasing momentum at the project,” said Ted Traum, Director at Rockrose. “We’ve been thrilled with the market’s response to our extensive repositioning, one-of-a-kind amenities and location directly facing Madison Square Park.”
