1) Tribeca: Glass staircases, a nautical-theme mosaic bathroom, sprawling terraces, hidden built-in beds?these are just a few of the custom features we saw in four impressive downtown homes. They'll all be open to visitors for annual design tours, but we got a sneak peek. Take a look.
2) Upper East Side: It's called the Waterfall Mansion for a reason; There's a 20' x 22' cascading waterfall and pond inside this 10,800-square-foot, five-story townhouse, which just returned to the market for $39 million, a $12 million price increase since June.
3) Tribeca: Telecom mogul Michael Hirtenstein created his massive Manhattan penthouse after seeing a billboard for One York. He bough not one, not two, but five units in the building and combine them into a triplex spread which includes 5,500-square-feet of outdoor space. Photos, right this way.
4) Upper East Side: Broadway producer Hal Prince's townhouse is fittingly theatrical. Wall-to-wall red velvet carpeting, zig-zagged bannisters, and astroturf inside are just a few of its quirks. But those things didn't stop the place from selling for more than $19 million.
