Description
BKREA has been retained on an exclusive basis to
arrange the sale of 42 East 23rd Street (“The
Property”), a remarkable eight-story commercial
building that is currently vacant.
The Property has a lot area of approximately 2,469
square feet and is located on the south side of East
23rd Street, with roughly 25 feet of frontage between
Park Avenue South and Broadway. It is just steps from
Madison Square Park and in close proximity to the
Flatiron Building, one of New York City’s most iconic
landmarks.
Constructed in 1905, 42 East 23rd Street comprises a
total of 17,078 gross square feet. The Property is
located within a C6-4M (R10 equivalent) zoning
district. The as-of-right zoning allows for a 10.0 FAR for
residential, commercial, and community facility uses,
translating to approximately 24,690 zoning floor area
(ZFA). Given the R10 equivalent, the site can achieve
up to a resi FAR of 12.0 or 29,628 ZFA through the
purchase of off-site UAP certificates from a generating
site within Community Board 5 or within one-half mile
of the Property. Alternatively, the additional 2.0 FAR
may be built on-site through the inclusion of affordable
housing.
42 East 23rd Street presents a blank slate for
developers, conversion specialists, office investors, or
owner-users to bring their new vision to life.BKREA has been retained on an exclusive basis to
