UWS CONSTRUCTION PORN: Official Zoning Diagrams For 226 W. 71st Penthouse Extension

Wednesday, May 8th, 2013

I’ve previously posted a couple of photos of the modern penthouse addition to the townhouse at 226 W. 71st (here & here).

Since then, my curiosity about the project has gotten the better of me and I managed to dig up two sets of official zoning diagrams that show some additional details.


The document on the left was the initial building plan filed in 2011. As you can see in the diagrams, the front of the penthouse was originally supposed to have a sloped top and the building’s bay windows were to be extended up the through the addition.

A second document (above right), filed in May 2012, changed the plans slightly and reflects the much boxier-looking addition that has been constructed.

In a post last week I pondered whether the lack of windows on the addition might be the result of a pool being constructed, but that doesn’t appear to be the case.

Rather, it looks like an elevator has been installed (it’s shown in the second filing but not the original). That, combined with the placement of the building’s stairwell, seems to account for the lack of windows.

In addition to the penthouse, approximately 10 feet of horizontal space has been added to the rear of the building (it’s 14 feet on the cellar and ground floors, including a greenhouse that extends into the backyard).

Overall, the building’s interior space has been expanded from about 5,000 to 8,000 square feet.

The townhouse is owned by an artist I’ve never heard of, but he’s clearly doing quite well for himself despite my ignorance.

H/t to MUW reader Fitz for the sleuthing inspiration.

    Since you are so interested in this, you might actually be able to answer a question I think of each time I look at this photo – the building to the right has a line of windows, with the lowest visible one right there over looking the new deck. Were there any windows below that one, which are now blocked by the new construction?

    Yes, I lived on the 8th floor of that building throughout the construction and the windows up to floor 6 or 7 were blocked.

    Yes, I lived on the 8th floor of that building (just above the additions) throughout construction and the windows up to the 6th or 7th floor were blocked by the addition.
