OPEN Impact secures 27,158 s/f for MoMath at 225 Fifth Ave.

Manhattan, NY According to OPEN Impact Real Estate (OPEN), National Museum of Mathematics (MoMath), the first museum in the United States dedicated to mathematics, has signed a short-term lease for 27,158 s/f on the ground floor and lower level retail space of 225 Fifth Ave. in NoMad.

Lindsay Ornstein, Stephen Powers, Jake Cinti and Julia Fish of OPEN represented the tenant, MoMath; Peter Whitenack of Newmark represented the landlord. The space was previously occupied by 24 Hour Fitness.

“Nearly 15 years ago, we embarked on a collaboration with MoMath to establish its initial location, aiming to transform the global perception of mathematics—an unproven hypothesis at the time,” said Stephen Powers. “Today, witnessing MoMath’s remarkable success and steadfast resilience, we eagerly anticipate the realization of their expanded vision in this new temporary location as we lay the groundwork for their permanent home.”

Since opening in 2012, MoMath has been in its current 19,000 s/f space at 11 East 26^th St. across from Madison Square Park. The museum, whose mission is to “enhance public understanding and perception of mathematics,” has dynamic exhibits and programs that “stimulate inquiry, spark curiosity, and reveal the wonders of mathematics,” including a special tricycle with square wheels that operates smoothly on a brightly colored catenary surface.

Additional details of the transaction, including the lease terms and asking rents, were not disclosed.  MoMath is expected to move to its new permanent location — which is projected to comprise 35,000 s/f — at the end of 2025. OPEN Impact Real Estate is representing MoMath exclusively in its search for a new, permanent location.

225 Fifth Ave. is located on the northeast corner of East 26^th St. and Fifth Ave. overlooking Madison Square Park. Nearby retailers include Eataly, LEGO, Porcelanosa, Shake Shack, Todd Snyder, Wagamama and Whole Foods Market.
