A
stunning 11-room penthouse on Fifth Avenue has hit the market for $11.5 million, just four months after its neighbor, a duplex owned by real estate mogul Barbara Corcoran, sold in a whirlwind transaction.

    The prewar duplex boasts an impressive light-filled sitting room and a wraparound terrace with breathtaking Central Park and city skyline views. The 15th-floor residence is located in the white-glove co-op at 1158 Fifth Ave., a building that dates back to 1924.

    Corcoran, founder of the Corcoran Group, sold her neighboring penthouse for $12 million just last month after listing it with an asking price below her total investment. The duplex next door has been renovated extensively and features five bedrooms, five full bathrooms, and a primary bedroom with a private terrace.

    The newly listed home was purchased in 2005 for $3.01 million and has had a few failed attempts at selling in the past, including a listing for $8.9 million in 2010 that ultimately expired after six months. The building offers luxurious amenities such as a 24-hour doorman and concierge, a live-in resident manager, a fitness center, and bike storage.

    The penthouse's "crown jewel" is its wraparound terrace, which provides unobstructed views of Central Park and the city skyline. The listing also highlights an eat-in chef's kitchen, formal dining room, and ample built-ins throughout the residence. With Corcoran's recent success in selling her neighboring home, it's likely that this penthouse won't be on the market for long.
