$10,600 per square foot

It was just announced that the full floor 8,255 square foot penthouse in the Rafael Viñoly-designed 432 Park Avenue (New York) has closed at a sale price of USD$87.7 million. That works out to be just over $10,600 per square foot.

It was purchased by Fawaz Al Hokair and is currently the most expensive sale in the building. However, the most expensive sale, ever, in New York remains the penthouse of One57, according to Curbed. It was purchased for $100.5 million.

Architecturally though, I much prefer 432 Park Avenue. I love its simplicity.

Each floor plate is 812 square meters. But because of the building’s height (424 meters / 1,395 feet) it appears a lot smaller. The ratio of building width to building height is about 1:15.

Because of this “slenderness ratio” the building is split up into 7 distinct volumes with a void between each. These voids – which are completely empty save for the building’s core – reduce wind loading and help with the building’s overall structural stability. (I’m sure it’s fine.)

The structural system is the exposed concrete grid. This leaves the interior of the floors completely column-free. Every window within this grid is exactly 10 square meters. 

Here’s a good interior example of that:

On a none architectural note, the building also features a private restaurant. I am curious how a private restaurant can operate sustainably in a building with 100 and some apartments owned by many people who probably don’t spend all (or much?) of their time in New York. Perhaps it’s partially carried by the ~$2.10 per square foot monthly maintenance fee.

Occupancy is available immediately if you happen to be in the market.
