The Sky House penthouse at 150 Nassau Street, a four-level, one-of-a-kind apartment wrapped around a four-story stainless-steel slide, has reportedly gone under contract after its $20 million listing. The 6,355-square-foot aerie stretches across the top four floors of the landmark American Tract Society building, with a 1,200-square-foot terrace and a long list of playful extras. The buyer is keeping a low profile so far, with no identity disclosed publicly.
According to The New York Post, which cited a StreetEasy update, the Sky House went into contract on June 1. The apartment was first listed in March at $20 million with Compass agents Nick Gavin and Ugo Russino. The Compass listing puts the interior at 6,355 square feet and notes monthly common charges of $14,143.
Slide, swing and a private playhouse
The star attraction inside is the multi-story stainless-steel slide that cuts through the penthouse levels, but the home does not stop there. There is also a rope swing, a rock-climbing column, glass floor cutouts and hidden ladders. StreetEasy's blog and earlier coverage by The Real Deal outline the whimsical renovations by architect David Hotson and designer Ghislaine Viñas. Their work helped turn the Sky House into a minor celebrity in the design world long before it hit the open market.
Historic shell, modern playground
The penthouse crowns the landmarked American Tract Society building, a late-19th-century Romanesque tower that was converted into condominiums in the early 2000s, according to the Compass listing. Public records compiled by Homes.com trace the unit's ownership history, including a 2007 purchase by Craig and Kristen Nevill-Manning for about $6.45 million. With its 23 stories, doorman service and shared roof deck, the building gives this high-concept interior a classic downtown backdrop.
Listing agent Nick Gavin has called the Sky House "one of the most architecturally rigorous penthouses ever built downtown," as reported by the Post. The rare mix of a historic exterior and a near-carnival interior has long made the property a favorite among collectors and design-focused buyers. With the home now in contract, the final sale price is likely to draw close attention from anyone tracking how eccentric, top-tier listings are faring in Lower Manhattan.
