The world's most famous skyline is getting skinnier and U.S. Immigration Fund projects, 125 Greenwich Street and 101 Tribeca, are no exception. Both projects, featuring luxury amenities, will stand out as iconic structures with their thin facade.

The Empire State Building, the Art Deco Chrysler Building, the super-tall One World Trade Center. New York City is home to some of the world's most iconic skyscrapers.
But the buildings entering its famous skyline today are doing something unusual. They're getting skinnier.

Take 111W57 on 111 West 57th Street. Upon completion in 2019, the 1,428-foot-tall (435-meter-tall) building in Midtown Manhattan will not only offer unobstructed views of Central Park, it will also be the slenderest skyscraper in the world, with a width-to-height ratio of 1:24.

Russia, meanwhile, is building its first supertall skinny skyscraper also in Midtown. Moscow-based architectural firm Meganom's "shelves in the air" will top out at 1,010 feet (308 meters) at 262 Fifth Avenue and boast a slenderness ratio of 1:20.
Both buildings are part of a tribe of slender climbers sticking their skinny necks into the city's architectural conversation.

What is a slender skyscraper?

Slenderness is not in the eye of the beholder when it comes to skyscrapers, at least. In this field, it is a technical engineering term. Whether it can be applied to a building is determined by the structure's base width to height ratio, according to Carol Willis, an architectural historian and founder of the Skyscraper Museum in New York City.

"Structural engineers generally consider skyscrapers with a minimum 1:10 or 1:12 ratio to be slender," Willis says.

In 2013/2014, the Skyscraper Museum museum presented its "Sky High & the Logic of Luxury" exhibition, documenting the rise of skinny structures in Manhattan. Slender buildings featured in the show included the 1,396-foot-tall (425.5-meter-tall) 432 Park Avenue; One57 aka "The Billionaire Building;" and the distinctive "stacked homes" 56 Leonard tower.

"New York's slender buildings are unique as a development in skyscraper history -- they're different to simply tall buildings," Willis says, adding that when deciding which skyscrapers to include in the show her team "accepted the slenderness ratios provided by their engineers."

Why slim down?

So when did developers start slimming down their skyscrapers -- and why?

Willis says the "engineering and development strategies of slenderness were first seen in around 2007." She pinpoints luxury residential condominiums One Madison Park, on Broadway and Park Avenue, and Sky House, between Fifth Avenue and Madison Avenue, as the first "slenders" to have cropped up in New York.

Complex zoning laws in the city were a motivating factor, Willis explains. While such regulations restrict the amount of land that can be built on within an area, a loophole allows for the transference of "air rights" from one plot to another. So developers could buy a small parcel of land, then buy air rights from adjacent plots and stack these to gain permission to build a tall tower. For example, if an existing building is shorter than its maximum allowed height then the developer of a new adjacent property could purchase the unused air rights, and stack them to the air rights of their existing plot -- such a transaction is called a "zoning lot merger."

Technological advancements also contributed to the rise of the skinnies.

"Over the past decade, advances in materials and engineering have made building 'supertalls' possible, specifically those with smaller footprints," says Jonathan Miller, president and CEO of New York real estate consultancy Miller Samuel. Towers between 980 feet (300 meters) and 2,000 feet (600 meters) high fall into the "supertall" category.

Standing out from the crowd

While developers typically strive primarily for return on investment, they often also want to create a structure unique enough to get the market's attention, says Miller. Slender designs, which come in all shapes and sizes, tick that box.

Take 111 Murray Street, in Tribeca, which will feature a curved, glass exterior and boast access to luxurious amenities including a concierge private jet service. Or 125 Greenwich Street, designed by award-winning architect Rafael Viñoly: the structure is supported by two beams that act as the framework of the building, resulting in minimal use of columns and more space in the interiors. Meanwhile, the 800-foot-tall (244-meter-tall) 130 William tower in lower Manhattan, by architect David Adjaye, will forgo a glass façade altogether in favor of stone and masonry, materials that pay homage to the history of the street it's located on.

"They are competing with other developers to stand out. The stakes are high financially, so design becomes a big part of the effort," says Miller.

Tall, skinny and good looking

Though the slenderness of a building is not defined by its height, slender towers do tend to be tall -- the "runway models" of the real estate world.

"Out of my window I can see one of these slender towers, which is 60 stories tall," Willis says. "The 30 stories at the top have an uninterrupted view of the skyline. So you're just setting the bar higher ... raising someone's neck, head and eyes above a crowd. "It lends a level of prestige that people are willing to pay additional money for."

Miller agrees. "In many cases this new generation are nearly twice as tall as the prior generation, going from 50 stories to nearly 100 stories, yet sitting on a much smaller footprint."

Supertall slenders can increase the desirability of their neighborhoods. "As a new class of building, they are not always in (traditionally) premier locations -- in fact, their tallness is often used to 'blaze a trail' in an untested residential location," says Miller.

He cites "Billionaires' Row", on 57th Street in Manhattan -- home to many slenders -- as an example.

"It is the central business district and (previously) not known for residential luxury buildings. The introduction of supertalls helped this location morph into a new identity as 'Billionaires' Row.'"

Setting an example?

New York is not the only place with a taste for slender skyscrapers.

In 2003, the 828-foot-tall (252-meter-tall), 75-story luxury residential tower Highcliff was opened in Hong Kong -- a city that, along with New York, has one of the most expensive real estate markets in the world, and a distinct lack of space on which to build. Highcliff has a slenderness ratio of 1:20. Upon completion, its developers claimed it was the slenderest residential property in the world.

Meanwhile, the 73-story Elysium Melbourne -- which measures just 12 meters wide at its narrowest point -- is set to become that Australian city's tallest and slimmest building. Its construction has been approved, although the completion date has yet to be confirmed.

In Sao Paulo, Brazil, AIR Madalena is a decidedly skinny residential property -- the 12 story building has a façade that is narrower than the average single-car garage.

It remains to be seen how long skinny stays in style.

From picnic baskets for park trips to a six-figure chauffeured car, here are the most ridiculous perks offered this year
By Ameena Walker  Dec 18, 2017 [caption id="attachment_24604" align="aligncenter" width="709"] Photo Credit- March.[/caption] New York City’s real estate market has seen its share of highs and lows over the course of 2017, but one thing hasn’t changed: the amenities offered at new luxury developments continue to get more and more ostentatious. Over the years, we’ve seen everything thing from concierge jet service to luxury yacht service; and while this year’s crop of developments didn’t include anything quite that over-the-top, we did see high-end experiences, chauffeur service, and a fair number of fancy pools. Here now, nine of the most exorbitant amenities offered to residents this year:
 Sky’s chauffeured Volvo
Penthouse residents of the Moinian Group’s enormous Sky development get access to a $105,000 chauffeured Volvo XC90 Excellence. The Sky Volvo features massage chairs with heating and cooling capabilities, crystal champagne flutes, and beverage warmers/coolers. This rarefied perk is only available between 4 and 9 p.m. and only travels between West 14th and 72nd streets between Sixth and Twelfth avenues.
Circa Central Park’s curated kids amenities
FXFOWLE’s semicircular condo building, Circa Central Park just might be home to some of Harlem’s showiest amenities. The Artimus Construction-developed building offers residents of its 38 pricey condos fully equipped picnic baskets that you can use during a trip to Central Park, remote controlled boats, kids scooters, and a study room (with MacBooks) for kids.
ARC’s 70-foot saltwater pool
Few buildings in Queens are as amenity-packed as Lightstone Group’s 10-story building, ARC, in Long Island City. The crowning jewel here is the rooftop’s 70-foot-long saltwater pool, accompanied by barbecues and bocce courts. Other highlights include a game room with vintage arcade consoles, a golf simulator, and a “dedicated outdoor exercise space.”
Waterline Square’s “club” with skate park
When starchitects Richard Meier, Kohn Pedersen Fox and Rafael Viñoly teamed up to design the trio of buildings known as Waterline Square, it was a sure thing that it would be anything but basic. Aside from boasting a pet spa and a dog training studio, there’s a shared amenity space, known as the Waterline Club, that comes equipped with an indoor tennis court, 30-foot rock climbing wall, swimming pool, an art and music studio, golf simulator, basketball court, indoor skate-park, indoor soccer field, “gardening studios,” and mini bowling alley. Fancy.
Urby Jersey City flower-arranging workshops
After last year’s debut of Urby in Stapleton, Staten Island, we’ve come to know a bit of what to expect from this community-focused brand. Urby Jersey City offers familiar amenities like a community coffee shop and cooking classes, but it also has a few new, slightly ridiculous perks—namely the the Urby Creative Lab, a corner one-bedroom that’s staged as a space for small workshops like flower arranging and Feng Shui.
Henry Hall’s jam room
The site that’s now home to Henry Hall, a high-end rental developed by Imperial Companies and designed by Ismael Leyva and BKSK Architects, was once where Legacy Records, a recording studio, once stood. To “pay homage” to that bit of history, the developers kitted out the building with a jam room for residents, with instruments and a karaoke set-up. That’s in addition to other over-the-top amenities like a roof deck, 24-hour concierge, a fitness center with “customized fitness programs,” and more.
555Ten’s bowling alley and pet spa
When it comes to amenities, Extell has earned a reputation for being the most extra, so it’s no surprise that its massive Midtown rental, 555Ten, is packed with over-the-top perks. Some are fairly standard—a rooftop pool and lounge, a sun deck, a high-end fitness center, a children’s playroom, and a game room. Others are a little more over-the-top: there’s a two-lane bowling alley as well as the pet spa/veterinary clinic run by Throw Me a Bone (get it?!).
 125 Greenwich’s pool with panoramic views
The amenity spaces in this Rafael Viñoly-designed skyscraper are being brought to life by superyacht designers March & White, so of course they’re over the top. The so-called “wellness amenities” at 125 Greenwich Street include a relaxation lounge, a spa, and a pool with a panoramic view of lower Manhattan. Other perks include a screening room, a private dining room, and a lounge.
300 Ashland’s “Apartment Stories”
Two Trees Management is experimenting with a slightly different approach to the amenity-sphere and looking to promote “experiences” as the hot new thing. The developer launched a program called “Apartment Stories” where “influencers” (like Rookie founder Tavi Gevinson) promote their buildings by hosting special experiences exclusively for residents. (The building also opened its expansive outdoor plaza this year, but that’s a little less exclusive.)    
NOVEMBER 9, 2017 BY DEVIN GANNON   Shortly after the launch of condominium sales last month, new renderings of 125 Greenwich Street were released Thursday, revealing its imposing height over neighboring Financial District towers (h/t YIMBY). The proposed 912-foot tall luxury condo designed by Rafael Viñoly Architects, the firm behind staggering 432 Park Avenue, features 273 total units, including 190 studios and one-bedrooms. Upon its completion, 125 Greenwich will have the third-highest apartments in lower Manhattan, after the Four Seasons Private Residences at 30 Park Place and nearly complete 45 Broad Street. The design of the residential building, developed by Bizzi & Partners and Vector Group, features rounded glass corners and two concrete-ribbons along the northern and southern sides of its crown. The design calls for nearly column-free layouts, high ceilings and many corner units.  Its Lower Manhattan location offers proximity to the World Trade Center and Wall Street, in addition to panoramic views. Instead of a sprawling penthouse on its top floors, there will be three floors of amenities, including private entertaining and dining areas, a 50-foot lap pool, a spa and fitness center. The interiors are being handled by the British firm, March & White, known for its sleek, simple designs. The original design of 125 Greenwich had the tower reaching supertall status at 1,400 feet tall. After lowering that plan to 898 feet, it grew slightly in its latest plan to 912 feet tall. Three-bedroom units, which span up to 3,960 square feet, are starting at $4.625 million. The tower is offering nearly 200 studio to one-bedrooms priced from $1.2 million. Notably, the studios are located above the 61st floor, giving smaller families and single professionals a chance to take in the sweeping views for less.
The top floors of the 912-foot skyscraper are devoted to swank amenities
BY AMY PLITT  NOV 16 [caption id="attachment_23672" align="aligncenter" width="719"] All renderings by March[/caption] After years in development (and the departure of one of its original developers, Michael Shvo), the Rafael Viñoly-designed skyscraper at 125 Greenwich Street finally launched sales this fall, bringing pricey condos to an area—just south of the World Trade Center—that’s not exactly oversaturated with them. (Helmut Jahn’s 50 West is its closest competitor, geographically speaking.) And because no high-end condo in New York City can be built without a bevy of equally high-end perks, developer Bizzi & Partners have kitted out the top floors of the 912-foot building with what’s being called The 88 (because the top floor is the 88th floor, naturally). Spread across three floors, the amenity space was fashioned by British superyacht designers March & White, who also did the building’s interiors and apartments. Curbed has the exclusive on the first renderings of those amenities, which are about as over-the-top as you’d expect. The 15,000-square-foot space has several different components: The top floor is given over to a fitness center with a weight room and yoga/pilates studio. It overlooks the “wellness amenities” on the 87th floor, which include a spa, a “relaxation lounge,” and a 50-foot pool with pretty incredible views. On the 86th floor, there’s a private dining room, a screening room, and a lounge, also with panoramic views. The whole shebang will debut when the building welcomes its first residents in 2019. Currently, more than a dozen of its condos are up for grabs, with the cheapest being a $1.275 million studio on the 66th floor (yep, the studios are on the higher floors here), and the most expensive being a $5.6 million three-bedroom on the 50th floor.

Rafael Viñoly's highly anticipated project at 125 Greenwich Street in Downtown Manhattan has entered sales just as construction resumes following the acquisition of a $450 million construction loan. The...
