Overview of The Milk Factory Building at 270 5th Street

The Milk Factory Building at 270 5th Street is a former Borden milk factory completed in 1911 and converted to a co-op in 1989. The four story, 33 unit property retains the scale and proportions of its industrial origins.

Apartments commonly have high ceilings, oversized factory windows and broad open living areas. Ceiling heights range from about 10 to 13 feet in single level homes to 18 to 23 feet in dramatic duplex lofts, several of which use upper level rooms or balconies overlooking the main living space. Wood burning fireplaces recur, while private outdoor space takes the form of roof decks, terraces and landscaped gardens, including several measuring 500 to 800 square feet.

The building has a central laundry room, video intercom, assigned private storage and a pet friendly policy; deeded parking also accompanies several residences. J.J. Byrne Park, the Old Stone House and the weekend Greenmarket are directly across the street, while the restaurants and shops of Fifth Avenue are one block away.

Sales History

Price/Room (Est)

Why are we displaying the estimated price per room?

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.
