Marx Realty announced Green Street Advisors has doubled its footprint with a new 12,000-square-foot lease at 10 Grand Central. The firm, known for its comprehensive research platform and media outlets that deliver exclusive news and data on the commercial real estate and finance markets, has been a tenant at the Grand Central office building since 2023. Green Street Advisors will move from its 5,000-square-foot second-floor offices to the 13th floor.
“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 Relty. “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.”
Ian Lipman of JLL represented Green Street Advisors. A JLL team of Mitchell Konsker, Thomas Schwartz, Carlee Palmer and Nicole Danyi represented Marx Realty in the transaction. The asking rent was $88 per square foot.
Marx Realty recently opened The Meeting Galleries – an 11,000-square-foot amenity space comprising four reservable spaces to accommodate board meetings, corporate retreats, company gatherings, product launches, team building activities, podcast productions and more – complements the 7,500-square-foot indoor/outdoor club floor added as part of the initial repositioning at 10 Grand Central in 2018. The Meeting Galleries provides a next-generation ‘town hall’ meeting lounge with seating for 200 guests (The Grand Gallery), a pre-function space (The Bar Car), a sound-attenuated podcast room (The Podcast Gallery) and a theater room (The Screening Gallery).
In a nod to nearby Grand Central Terminal, The Meeting Galleries space features a luxury train liner aesthetic harkening back to the 1930s. Finishes inspired by Guastavino tiles complement oversized murals and custom art pieces fashioned in oxidized copper. Gold-backed murals create a ‘garden party’ feel and lend an art gallery-like sensibility throughout the different spaces, each appointed with a variety of seating options. Oversized windows with soft, rounded edges mimic those found on train liners and infuse the space with natural light while private nooks with fold-down tables add timeless sophistication and contemporary functionality to the space.
10 Grand Central also offers tenants an upscale house car for transportation around Manhattan. The Marx Mobile is a branded electric Porsche Taycan which serves as an on-demand rideshare option available to all the building’s tenants through the company’s proprietary MarxConnect software.
Studios Architecture, together with Marx Realty’s in-house design team, led the redesign of the building as well as designs for the comprehensive amenity package.
