Why anyone would want to leave this gorgeous Carnegie Hill penthouse at 1150 5^th Avenue will remain a mystery for the ages. For some reason, the penthouse’s former owners, Karim Rashid and Tracy Buescher, have decided to sell their beautiful 5th Avenue pad. However, someone just hit the jackpot when they scooped up the 3BR/3.5BA beauty, built in 1924 by J.E.R. Carpenter – the unsung hero of 5^th Avenue. The co-op was designed by architect Charles Platt, the award winning designer responsible for Washington D.C’s Freer Gallery of Art.

Who knew bloggers could afford $14.9 million apartments? David Alan Stockman, of David Stockman’s Contra Corner (and other things discussed after the break), and his wife Jennifer, an art collector and the current president of the Guggenheim Foundation’s board of trustees, have just purchased a 5BR/6.5BA penthouse at 170 East End Avenue through brokers Andrea Wohl Lucas and Bruce Lucas of Corcoran.

Though the building itself isn’t much to look at, this 4,902-square-foot penthouse makes up for its stark, stacked exterior with a well-thought-out floor plan designed to make the most of the location’s natural light and sweeping views of the East River, neighboring Carl Schurz Park, and the cityscape.

Apartment 7C, a palatial apartment at 911 Park Avenue has been sold. Marsh CEO Peter Zaffino purchased the astounding pre-war pad for $6.75 million.

This Upper East Side beauty, represented by brokers Debra LaChance and Denise LaChance, has 10 rooms, with 4 bedrooms, 4 bathrooms, and marble floors and hardwoods throughout. The high-rise also features a private landing, a library and a great room with a wood-burning fireplace for those cozy nights by the fire.

It also contains an enviably large eat-in kitchen and the increasingly elusive formal dining room. The library features wall-to-wall built-ins and the entire apartment boasts coffered ceilings.

It’s a great market for townhomes. 54 East 64th Street has been sold to designer Reed Krakoff and his wife Delphine for $28 million.

This news is especially remarkable considering the townhouse’s history. Formerly a Kips Bay Decorator Show House and a one-time home of the New York Observer, this Upper East Side gem was transformed into a luxurious home when it was purchased by real estate investor David Quinlan for $18.74 million back in 2005.

After failing to turn the hefty profit he was hoping for, Quinlan sold the townhouse for $20 million in 2011. Last year it was placed back on the market for $20 million; however, broker Dolly Lenz changed that, upping the asking price to $28 million. They don’t call her a superbroker for nothing.

Vestar Capital founder and co-president Robert Rosner and his interior designer wife have snapped up a 14th floor condo at 1095 Park Avenue.

The couple was previously in the former Stanhope Hotel, a 1926 Rosario Candela jewel box at 995 Fifth Avenue opposite the Metropolitan Museum of Art, that was converted into luxury condos. Their new abode features the same modern, streamlined aesthetic of their previous space — a style which Mrs. Rosner has once described as “a chic and sleek downtown sensibility in an iconic uptown setting.” Do you agree?

According to property records filed with the city in Friday, it appears that George Stephanopoulos is moving on up in his 30 East 72nd Street co-op!

The Good Morning America co-anchor and his comedian wife, Alexandra “Ali” Wentworth, purchased a sizeable 2BR/2BA apartment located on the 10th floor of their current building for $2.2 million. The pair already own a 3,300-square-foot, ninth-floor apartment at the same property, purchased for $6.5 million in 2010. Word is that the couple will merge the two apartments into one luxurious home.

Society couple Pamela Farkas and Andrew Paul have finally found a buyer for their co-op at 820 Park Avenue.

The duo placed their property on the market last September, and it looks like Wall Street exec Matthew Cherwin, who was recently named co-head of JPMorgan’s Global Credit, Securitized Products and Public Finance, and his wife, Wendy Cherwin, handed over $22 million for the digs. The interiors of the duplex are definitively Upper East Side, and the residence boasts five bedrooms and 180-feet of Park Avenue frontage.
