Block by block, the line of demarcation between “prime Tribeca” and Tribeca is slowly creeping south. New York– and Paris-based Post-Office Architectes recently unveiled a 12 story, 23 unit luxury residential building at 30 Warren Street.

Last October, AN reported on 30 Warren’s neighbor, 12 Warren, a DDG-designed residential building less than a block away. While 12 Warren’s bluestone-clad facade sets it apart from neighboring buildings, 30 Warren asserts itself with a full block takeover of Church Street, between Warren and Chambers streets. Along the block’s busy streetwall, the development includes approximately 9,700 square feet of ground floor retail.

“The design of 30 Warren is purposely asymmetrical arranging for an intentional void, staggered floors on the west side, and a southern facade with two setbacks to take full advantage of the views of the Manhattan skyline, the skyscrapers in the Financial District and the river,” explained Post-Office Architectes principal Francois Leininger in a statement. “We focused on framing the amazing views and arranged a sequence of large picture windows to capture the grand moments of the city. The framed views were determined from the interior of the units as a way of bringing the city into the residences without overexposing its occupants.”

Most of the picture windows are single pane, including the 13-foot-long living room window in each unit. To minimize noise, windows on the Chambers Street side are triple-glazed, the New York Times reports. The exterior walls will be coated with reinforced, one-inch-thick concrete, giving the building a semi-industrial feel that dialogues with its grittier neighbors.

The one- t0 three-bedroom units range in size from 1,000 to 2,500 square feet. There is not one, but three, floor-through penthouses. (The physics of luxury development defy comprehension.) 30 Warren is expected to be complete by fall 2017.
