Mill Rock Plaza

Mill Rock Plaza at 345 East 93rd Street is a 32-story luxury doorman building in the Upper East Side neighborhood of Yorkville in Manhattan. The building name actually comes from a small rocky island in the “Hell Gate” section of the East River that is home to a park no longer open to the public. The building currently houses a total oapproximately 285 one, two, three, and four bedroom apartments (down from 310 due to the number of combinations created by owners).

It was built in 1975 as apartment rentals with the convertion to cooperative ownership taking place a decade later in 1985. Since that time, the building, with secure access to the parking garage below, has made a number of improvements including a fully-renovated lobby and hallways that were designed and executed by the Sygrove Associates Design Group. The renovation also delivered a residents-only modern fitness center, bike storage room, state-of-the-art mailroom and package system, automatic doors at both the 93rd & 94th Street entrances, and updated laundry rooms on each and every floor. In 2020, the building made two additional upgrades: the sundeck was professionally landscaped and furnished and new PHTP heating & air conditioning units with wireless thermostats are replacing earlier PTAC units in a rollout that is expected to be completed by the summer of 2021.

Apartments at Mill Rock Plaza are larger than most buildings in the area, with one-bedroom units averaging more than 700 square feet and most middle and upper floor units delivering spectacular views of the East River and city skyline. With many families and pet owners living in the building, the resulting atmosphere is informal, diverse, and truly pet friendly.

The cooperative board is very reasonable with purchase applications, provided applicants have sound financials. Applications are due the last Tuesday of each month and Interviews are conducted monthly, also on Tuesdays, by the board of directors.
