The building
The Forum, which was designed by architect Elliott Vilkas, is often noted from a distance for its pronounced sloping curtain wall on the building's south side. The sloping glass wall was designed to provide optimum light for the duplex and triplex units that occupy the top floors. The building's massing is also noted as unique for a midblock building, with roughly half of its frontage set back to create a small plaza along 74th Street featuring two-story arched windows at the base of the building.
The apartments in the building range in size from 550-square-foot (51 m2) studios to 1,900-square-foot (180 m2) three-bedroom penthouse units. The building's top five floors make up a penthouse complex, comprising a small number of large three-bedroom duplex and triplex apartments.
The Forum is located roughly equidistant between First and Second Avenues, whereas taller buildings in Manhattan are typically located at the corner intersection of an avenue due to zoning restrictions.
