The Tower Building was a structure in the Financial District of Manhattan, New York City, located at 50 Broadway on a lot that extended east to New Street.

[1] Architect Bradford Gilbert filed plans for its construction on April 17, 1888, it was completed on September 27, 1889 and demolished beginning in 1913.

[4][5] On the narrow lot, a conventional design with load-bearing masonry walls would have left little room on the ground floor, but architect Gilbert asked, "Why can't I run my foundation far up in the air and then begin my building?

[8] Gilbert made models to convince the city to permit the construction of his unusual design.

[8] No longer profitable by 1913 due to its lack of tenants, it was vacated in December of that year and demolition began.
