Rich New Yorkers are connecting neighboring townhouses or building floors to create supersized mansions. Owners include Madonna and Sarah Jessica Parker.
When an apartment or penthouse isn't big enough for wealthy New Yorkers, they get creative.
In recent years, several have combined multiple townhouses or building floors to create supersized homes — or Frankenmansions, as New York magazine's S. Jhoanna Robledo calls them.
To construct these Frankenmansions, some prospective buyers purchase multiple buildings at once, while others approach their neighbors to offer multimillion-dollar buyouts. (In either scenario, they need the city's approval before combining properties.)
Check out these 12 Manhattan Frankenmansions owned by big names — including Madonna, Sean Parker, and Sarah Jessica Parker — outlined below in red.
Bloomberg has bought five of the six apartment units in the building next to his 7,500-square-foot townhouse over the last three decades. After connecting four units in 2009, he grew his home to 12,500 square feet, according to the New York Post. The buildings are steps from Central Park.
The Missionary Sisters of the Immaculate Heart of Mary, an NYC-based convent of nuns, acquired the townhome on the right in 1948. Four years later, the group bought the one next door and connected them via a doorway on each floor.
Throughout the years, the order has rented some of the complex's 25 bedrooms to other congregations or young women in need. But the Frankenmansion may soon find a new owner — the 15,600-square-foot space went on the market in 2016 for $19.8 million, according to The New York Times.
The star of "Sex and the City" snatched the two brick townhouses above from the nonprofit United Methodist Women, then fused them. The organization listed the pair of buildings (which were not connected) for $44 million in 2016, but Parker paid $34.5 million, according to The Real Deal.
The 13,900-square-foot mansion includes nine bedrooms, eight bathrooms, a 2,100-square-foot private garden, and five floors.
Sean Parker, the former president of Facebook, owns the three brownstones pictured above. Each building originally contained four apartment units, a grand stairwell, and a rear garden. The interior spaces feature arched doorways and original 19th-century fireplaces with marble mantles.
Parker purchased the first building for $20 million in 2010, the second for $16.5 million in May 2016, and the third for a reported $22 million in August 2016. He completed the renovation to connect all three in late 2016.
The billionaire Jon Stryker is the rumored owner of the two brick buildings above, which the NYC-based firm Steven Harris Architects is working to turn into one residence. Curbed reported that Stryker was likely the buyer of the $32 million set in 2012. The renovation project was approved by the city in October.
In their former lives, the buildings were an ice cream factory, a Steinway piano showroom, and a garage. The property's facade will stretch 41 feet.
In 2009, Madonna bought three connected townhouses on Manhattan's Upper East Side. The $32 million mansion features 13 bedrooms, a dance studio, multiple dining rooms, a 3,000-square-foot garden, two garages, an elevator, and a private gym, according to Curbed.
The facades will be preserved, and the center house will become the mansion's main entrance after construction is complete. The interiors will be completely renovated, and the backyard will feature a private garden.
Owned by the billionaire Safra family, the two limestone townhouses above were listed for sale in 2015 as a trio with the building on the right. The asking price was $120 million, but in 2016, the owners asked for $75 million for just the pair, which sold in early 2017 and will likely be combined, according to Curbed.
A total of 25,641 square feet, the soon-to-be Frankenmansion would feature 18 bedrooms.
Feinstein bought the townhome on the left for $3 million in 2004, according to The New York Times. A year later, the one next door went up for sale for $3.8 million, and Feinstein purchased, gutted, and renovated it to connect the two.
The finished product features 18 rooms, twin staircases, seven bathrooms, two powder rooms, eight fireplaces, a 25-foot-wide backyard, and two pagodas, which serve as outdoor living and dining areas. He put the mansion on the market for $17.9 million in 2013 but later decided to keep it.
In June, Altice CEO Dexter Goei bought two townhouses in Manhattan's Greenwich Village for $31 million, according to The Wall Street Journal.
The Real Deal reported in October that converting them into a mega-mansion was expected to cost $1.3 million. The renovation will be led by the architecture firm Arcologia.
Jeff Koons, the artist known for his giant sculptures of balloon animals, purchased the townhomes pictured above for $32 million in 2009, according to Curbed.
A year later, he applied to NYC's Department of Buildings to combine them into a 21,500-square-foot mega-mansion, but the request was denied. In 2013, he submitted a revised proposal, and the renovation started soon after.
Lauren Bush Lauren, the granddaughter of former President George H.W. Bush, bought a trio of townhouses for $28.5 million in 2014, along with her husband, David Lauren, the New York Post reported.
The renowned photographer Annie Leibovitz was the previous owner. She bought the first two townhouses in 2002 for $4.2 million. A year later, she purchased the neighboring one on the corner for $1.9 million, then combined the three.
The compound stretches 10,200 square feet and features seven bedrooms, 5.5 bathrooms, 13 fireplaces, and a private gated garden.
