Jan Koum, the co-founder of WhatsApp, is paying approx. $109 million for a Malibu, Calif. mansion right next door to one he already owns, according to two people familiar with the deal.

The transaction is the latest big-ticket deal for Mr Koum in the Los Angeles area. In 2019 he purchased the neighbouring Malibu property from entertainment executive Ron Meyer for around $126 million. Then last year Mr Koum spent approx. $157 million for the Beverly Hills estate of Quibi founder Jeffrey Katzenberg.

The seller in the latest transaction is Diana Jenkins, a Bosnia-born entrepreneur and philanthropist. Ms Jenkins, founder of health-drinks company Neuro Drinks, was previously married to British financier Roger Jenkins. Her home came on the market last May for US$125 million, The Wall Street Journal reported. It is on Malibu’s Paradise Cove, and its prior owners include Barry Diller and the late country singer Kenny Rogers.

Sitting on a cliff top, the property has its own funicular leading down to the ocean (Mr Rogers was slapped with a US$2 million fine by local authorities for installing it.). On nearly 3 acres, it includes a single-story, five-bedroom house with vaulted ceilings, herringbone floors and floor-to-ceiling windows that open onto the gardens. It also has a dance studio and a recording studio. On the grounds, there is a three-bedroom guesthouse, a swimming pool, a waterfall and koi pond, a sports court and a guard house.

The funicular leads an oceanfront cabana, which has retractable ceilings, a wet bar, a built-in barbecue and fire pit.

Mr Koum, 44 helped launch WhatsApp, an internet messaging service, in 2009. Following the service’s acquisition by Facebook in 2014, he remained as a Facebook director for several years before stepping down in 2018. The Bloomberg Billionaires Index pegs his net worth at $15.7 billion.

Chris Cortazzo of Compass has the listing. The buyer was represented by Kurt Rappaport of Westside Estate Agency.

Listing of the Day

Location: Downtown Brooklyn, New York

Price: $16.75 million

Boasting 360-degree panoramic views across New York City, this new 92nd-floor penthouse is the highest residence in Brooklyn.

The full-floor apartment stands atop the new Brooklyn Tower, which encompasses 143 condos and 398 rentals in the heart of downtown Brooklyn, said Katie Sachsenmaier, senior sales director, Corcoran Sunshine Marketing Group.

The condos begin on the 53rd floor, and the penthouses begin on the 88th floor. This one, Penthouse 92, is the only full-floor penthouse.

“The building is coming into its own now,” she said. “It feels very busy when you step into the lobby.”

Developed by Silverstein Properties, the building at 85 Fleet Street rises from the historic Dime Savings Bank building, according to a news release.

It was designed by SHoP Architects with interiors curated by Gachot Studios, and it is the borough’s only super tall skyscraper.

Penthouse 92 features custom interiors by Brooklyn-based Susan Clark of design firm Radnor, Sachsenmaier said. “Her selections have made it really beautiful. It feels very warm and inviting.”

Architectural details include 12-foot ceilings, European white oak floors in a custom honey stain, mahogany millwork, bronze detailing and floor-to-ceiling windows.

The eat-in kitchen features Absolute Black stone countertops, an island with seating, oil-rubbed bronze Waterworks fixtures and integrated Miele appliances, according to the listing.

The primary en suite bathroom showcases large-format Honed Breccia Capraia marble. There is also a separate laundry room as well as a wet bar and a butler’s pantry.

The views are spectacular, Sachsenmaier said. “If you’re standing in the living room, you take in the Statue of Liberty and all the way up through Midtown. On a clear day, you can see the planes take off at LaGuardia (Airport).”

Moving around the apartment, you see south over the harbor and then north and east over the whole city, she said.

From the front door, “you’re immediately greeted with the expansive living room and the view,” she said. “It’s really the first thing you see.”

The primary suite features a dressing room, multiple walk-in closets, two bathrooms (one with a cedar sauna) and southwest-facing windows, Sachsenmaier said. “You get those really beautiful harbour views.

The amenities will be ready by the end of summer, she said. A Life Time club will occupy the entire sixth and seventh floors, and an outdoor pool deck wraps around the dome of the bank building.

Stats

The 5,891-square-foot home has four bedrooms, five full bathrooms and one partial bathroom.

Amenities 



Residents will have access to over 100,000 square feet of exclusive indoor and outdoor leisure spaces.

Fitness company Life Time will manage an array of amenities that include a 75-foot indoor lap pool, outdoor pools, a poolside lounge and atrium, a billiards room, a library lounge, a conference room, a theatre with a wet bar, a children’s playground and playroom and limited off-site parking.

Neighbourhood Notes 



Downtown Brooklyn is at the centre of a number of neighbourhoods, including Fort Greene, Cobble Hill, Boerum Hill and Brooklyn Heights. The tower has access to 13 subway lines, 11 commuter trains, the city’s ferry network and 22 Citi Bike stations.

“You can walk to Fort Greene Park in less than 10 minutes,” and Dekalb Market Hall, which has a Trader Joe’s, a Target and a food hall, is “right next door,” Sachsenmaier said.
