National Museum of Mathematics (MoMath) has signed a short-term lease for 27,158 square feet of ground floor and lower level retail space at 225 Fifth Ave. in NoMad. Currently housed at 11 East 26th Street, MoMath is planning for a permanent 35,000-square-foot home by the end of 2025. 

Lindsay Ornstein, Stephen Powers, Jake Cinti, and Julia Fish of OPEN represented MoMath in the lease transaction. Peter Whitenack of Newmark acted on behalf of the landlord. Details of the lease terms were not disclosed. 

“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,” stated 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.”
