Peter Huang, an investor whose ex-wife tossed wild Studio 54-era parties in his duplex apartment at 740 Park Avenue, has re-listed the place after it failed to sell 2011, reports the Wall Street Journal’s Candace Taylor. Then, it was listed for $29.5 million. Now, it can be had for $2 million less through broker Kyle Blackmon, the 15 Central Park West resident who sold Sandy Weill‘s penthouse at 15CPW to Russian oligarch Dmitry Rybolovlev for $88 million. The buyer will have among his or her neighbors Will Zeckendorf, one of 15CPW’s developers.
