451 Broome Street is the co-op conversion of the former Silk Exchange office building, a New York City Landmark constructed in 1895. The 13-story, 25-unit building has three elevators, a full-time superintendent, a video intercom, and private storage in the basement. It is located in the heart of the Soho-Cast Iron Historic District near Tribeca, the Lower East Side, and the Village. Pets, pied-a-terres, and sublets are permitted with board approval.
Limited off-market opportunities might be available at Silk Exchange Building – ideal for those looking to explore listings not currently on the market. Contact us to learn more.

For some co-ops, instead of price per square foot, we use an estimate of the number of rooms for each sold apartment to chart price changes over time. This is because many co-op listings do not include square footage information, and this makes it challenging to calculate accurate square-foot averages.
By displaying the price per estimated room count, we are able to provide a more reliable and consistent metric for comparing sales in the building. While we hope that this gives you a clearer sense of price trends in the building, all data should be independently verified. All data provided are only estimates and should not be used to make any purchase or sale decision.
