The penthouse's volumetric ceilings and open living spaces create a seamless environment in which to relax, entertain, and simply retreat.
In 1857 Obsidian House was built by one of New York’s most prominent families—the esteemed Joneses, from which celebrated author Edith Wharton was descended—making it one of the oldest cast iron buildings in New York City.
Designed in the Italianate style, the building’s ornate façade is split into four bays at each story and punctuated by fluted Corinthian columns. At the time of its construction, the building was considered one of the most impressive structures in lower Manhattan, and it helped give rise to the common trope: "Keeping up with the Joneses." After the Jones family sold the building in 1889, it became the commercial home for a number of prominent merchants. Today, Obsidian House has reemerged and is once again one of Tribeca’s most striking residences.
In 2015 the cast iron building at 93 Reade Street was reimagined by the acclaimed architecture firm WORKac as Obsidian House. Named for its unusual extruded roofline—which evokes jagged forms of volcanic rock—Obsidian House is home to three spacious loft residences and one exceptional three story penthouse. From the external restoration to its modern interiors, Obsidian House has been updated in a manner that honors the building’s rich history, while also offering a creative interpretation of contemporary luxury.
The inventive team at WORKac—the architecture firm that designed Diane von Furstenberg’s flagship store and private penthouse (the "Living Cube"), the New York offices of renowned advertising firm Wieden+Kennedy, and an addition to the Blaffer Art Museum in Houston, Texas—have applied their singular, unique vision to the penthouse at Obsidian House.
Spanning three floors that flow seamlessly from one to the next, the penthouse features five spacious bedrooms, a sitting room, an open living dining room, and an expansive rooftop terrace with a spa tub. The dramatic double height living room opens directly onto this intimate terrace, creating a fluid space for indoor and outdoor entertaining. The penthouse’s signature pleated ceilings evoke natural, organic shapes, while still feeling thoroughly modern and urban—a rare balance that distinguishes WORKac’s designs.
