361 Broadway

[3] The building was designated a New York City landmark on July 27, 1982,[3] and was added to the National Register of Historic Places on September 15, 1983.

[7][8] A gut renovation was completed in 2021, with contemporary double-height living spaces inserted behind the restored cast-iron façade.

[9] As part of the project, the existing floor slabs were removed, and the six-story structure was expanded to seven stories.

A two-story penthouse structure, with two duplex apartments, was installed on the roof of 361 Broadway using a Vierendeel truss system.

[10] To avoid adding stress to the historic façade, the independent structural system was devised to manage the additional load of the new penthouse floor using the existing foundation.
