The month’s biggest co-op sale was a stately unit on the 10th floor of the 12-story 960 Fifth, at East 77th Street, designed by Rosario Candela in the late 1920s and considered one of the city’s grandest apartment houses.
The residence had been the longtime home of C. Douglas Dillon, Treasury secretary in the Kennedy administration and ambassador to France under President Dwight D. Eisenhower. He died in 2003.
It was sold by Mr. Dillon’s estate to Ms. Lauder, who is the founder of Aerin, a beauty, home and luxury lifestyle brand that she started in 2012.
Ms. Lauder will get a chance to put her home-design chops to good use in this 13-room residence, which has five bedrooms and six full baths and comes with a storage room, as well as panoramic views of Central Park and the city skyline.
The home is entered through a spacious formal gallery that opens to the entertainment spaces — a living room, library and formal dining room adorned with ornate fireplaces and decorative moldings, according to the listing with Sotheby’s International Realty. The south wing contains the main bedrooms, each with an en suite marble bath. The staff quarters and kitchen are on the north side.
Mr. Cheeks of NBC and Laurence M. Hausman, an anesthesiologist and professor at Mount Sinai Health System, bought and sold at 425 West 50th Street, a.k.a. Stella Tower. After selling their penthouse duplex for just under $6 million, they bought a larger penthouse in the same building for nearly $7.3 million.
Their new home is 3,455 square feet, with four bedrooms and three and a half baths, according to the Sotheby’s listing. The unit also has 1,074 square feet of outdoor space, including a rooftop terrace with expansive cityscape views.
The recently sold 2,688-square-foot penthouse, which Mr. Cheeks and Dr. Hausman had bought last year for $6.7 million, contains three bedrooms, four and a half baths and a 644-square-foot terrace.
Mr. Cheeks is a vice chairman of NBCUniversal Content Studios and in charge of the network’s late-night lineup.
The townhouse sold by Mr. Unterberg and his wife, Ann Unterberg, both philanthropists, sits in the Upper East Side Historic District, at 49 East 67th Street, off Park Avenue. The unidentified buyer, who made the purchase through a limited liability company, paid $11.8 million; it had been listed for as much as $26 million in 2016.
The 1878 brick house is five stories high and 20 feet wide, with nearly 9,000 square feet of interior space, including a finished basement that has a sauna and access to a neighboring co-op’s pool, according to the Corcoran listing. Outdoor space includes a landscaped rear garden and two terraces, one off the master suite and another off a fourth-floor bedroom.
The fully renovated house has six bedrooms, five full baths and two powder rooms. There are also six wood-burning fireplaces, a skylight on the top floor, and at the parlor level, a glass-enclosed solarium overlooking the garden.
A five-story brownstone on East 64th Street, a block from Central Park, sold for $9.7 million. Mr. Steinberg of Cheddar, who is also a former president of BuzzFeed, and his wife, Jill Steinberg, were the buyers. The seller used a limited liability company in the transaction.
The fully renovated house, built in the late 1800s, has around 7,500 square feet of space. It features five bedrooms, five and a half baths, a family room and eight fireplaces. Outdoor space includes a large roof deck, a patio off the kitchen and a terrace on the third floor, where the master suite is situated.
Also closing in November:
Several more apartments sold at 15 Hudson Yards, the first residential building to open in the megaproject. The largest of these sales, at $8.5 million, was a three-bedroom, three-and-a-half bath unit.
The Fifth Avenue apartment of Eugene M. Lang, an investor and philanthropist who famously promised to pay the college tuition of sixth-graders in Harlem who completed high school. He died two years ago, and his fourth-floor co-op unit at 912 Fifth was sold by his estate for $3.3 million to Ronald Peltier, the founder and former chief executive of Berkshire Hathaway’s HomeServices of America.
And then there’s what you might call a “model” apartment in TriBeCa. This 4,215-square-foot loft, at 44 Laight Street, near Hudson Street, comes with its very own custom steel catwalk, along with three bedrooms, two full and one half-bath, and a glass-enclosed media room. (The catwalk provided a whimsical connection from a billiards room to the media room, both on raised platforms.) The apartment was sold for nearly $4.7 million by Cory Margolis, an owner of Mantiques Modern in Chelsea, and Jacqueline Margolis. The buyers were Samuel Hayden Powell and Elyssa Beth Kaplan.
