Another day, another over-the-top penthouse created by a starchiect makes its debut on the real estate market. This time it's actually two penthouse units at 20 East End Avenue, the 43-unit building designed by Robert A.M. Stern. The "penthouse collection," comprising the uppermost floors of the new building, hit the market today (after a bunch of other listings went on sale earlier this year), asking $35 million (for Penthouse A) and $27 million (for Penthouse B). Both units measure more than 6,000 square feet, and both have five bedrooms and five-and-a-half bathrooms, along with fireplaces and high ceilings. Where they differ is in the outdoor space, which PHA has in abundance: there are four terraces that surround the top of the building, and there's even an outdoor fireplace. (PHB also has a terrace that measures about 300 square feet.) Other amenities include open chef's kitchens in both, spacious master bedrooms, oak floors, and "generous wall space to display one's private art collection." (Perhaps a Degas, as the photos would have you think.) And you're paying for the name, too: Stern's firm designed the building's interiors, in addition to the exterior.
