In NYC’s biggest residential deal ever, a duplex penthouse at the bar-raising luxury Midtown tower One57 at 157 West 57th Street was purchased for over $90 million. We’re told the buyer is 1) a well-known name, 2) planning to live there with family and 3) not Russian. Otherwise, the buyer’s identity remains a mystery. The building, which will be complete next year, is already half sold, according to the project’s developer. The sale surpasses the $88 million sale earlier this year at 15 Central Park West (CurbedNY).

April 2012 was a good month for new NYC condos. Manhattan reportedly saw 127 units go into contract, up 21 percent from the same month in the previous year, with downtown Manhattan, home to popular buildings like the Chelsea Enclave at 177 Ninth Avenue and 48 Bond Street, leading the way. The median price of Manhattan listings in April reached $1.5 million, up 10.1 percent from the previous year (via Crains NY).

A new–as in, not-yet built–Chelsea condo at 151 West 21st Street has officially launched sales. Units at the 51-unit Chelsea Green–from the same developer responsible for the popular eco-friendly Village Green at 311 East 11th Street in the East Village–start at $799,000 and range from one to three bedrooms plus a four-bedroom penthouse (CurbedNY).

It may sound like the punchline of a housing bubble joke, but a parking space in a private garage at 66 East 11th Street–across the street from the Cast Iron Building co-op at 67 East 11th Street–will soon be available for $1 million. The building above the parking garage is being converted to six luxury condominiums which will be topped by an 8,000 square-foot duplex penthouse. The city’s second priciest parking spots can be found in the “en suite sky garages” at 200 11th Avenue (NYPost).
