The Forum at 343 East 74th Street, Residential condop tower in Lenox Hill, Manhattan, US.
The Forum is a 25-story residential tower on East 74th Street between First and Second Avenues, distinguished by a sloping glass curtain wall on its southern side. Inside are 149 units ranging from compact studios to spacious penthouses, each equipped with in-unit laundry facilities.
The building opened in 1987 as one of Manhattan's first condop structures, introducing a new ownership model blending condominium and cooperative features to the Upper East Side. This model emerged from the need for mixed-use property arrangements that offered both residential ownership and shared community benefits.
The building stands among educational institutions, including The Cathedral School and Eleanor Roosevelt High School, contributing to the neighborhood's educational landscape.
The main entrance is accessed from East 74th Street, with easy pedestrian access throughout the surrounding area and convenient public transportation connections nearby. The neighborhood offers walkable shopping and dining options within short distances of the building.
The building operates under an unusual 149-year ground lease from the neighboring church, running from 1987 through 2136. This arrangement was a creative solution allowing development on church-owned land while maintaining a long-term relationship between the property and the religious institution.
