Sun Microsystems co-founder Bill Joy has never lived in the 176 Perry Street triplex he bought for $17.57 million five years ago, but it still may go down as the best home he ever owned. That's because Joy is looking to get a whopping $40 million for the 11,000-square-foot slab of Richard Meier minimalism, a nice profit even after hiring Meier to also design the interior. The unit is the biggest in the building (it's the southernmost Meier-Perry tower), occupying the entire eighth through 10th floors. Calvin Klein owns the penthouse a few floors above. The triplex listing is now online, and the photos offer a look deep into the heart of Meiermania.
