One of New York’s oldest landmarks is home to the city’s coolest apartment. Completed in 1896, 150 Nassau Street was originally designed as the headquarters for the American Tract Society. The religious printing house moved out of the beautiful Beaux Art skyscraper in 1914 and like a lot of historic New York City buildings, it has since been transformed into luxury condos.

As with all penthouses, the top floor of the 23-story structure — appropriately dubbed the SkyHouse — boasts stunning views of the Big Apple’s most beloved landmarks, including the Empire State Building and the Brooklyn Bridge. What sets the four-story home apart, however, is its distinct layout and one-of-a-kind accents, courtesy of architect David Hotson and interior designer Ghislaine Viñas.

The most impressive feature is a mirrored, stainless steel slide that measures 80 feet and winds through the entire 6,600-square-feet space. There’s also a climbing wall built out of a riveted steel column that stretches the entire height of the 50-foot-tall living room.

In his design, Hotson cleverly highlights the surrounding cityscape in a Where’s Waldo-esque game. There’s a peephole the a bedroom shower that captures the glow of the Chrysler Building, a secret window in a medicine cabinet that looks out onto the Manhattan Bridge and a skylight that frames the top of neighboring New York by Gehry building. Viñas plays off Hotson’s layout with equally whimsical additions and accents that pop off the mostly white space, such as floral-patterned couches and pop-art murals.
