The unbridled luxury promised for Chelsea’s new mansion is finally visible, courtesy of Wonder Works Construction’s new interior renderings. Developed in partnership with Girona Ventures, the five-story mansion will retrofit a four-story walk-up at 357 West 17th Street. The team tapped Workshop Design + Architecture and Andres Escobar to transform the existing structure into a 12,000-square-foot mansion, complete with five bedrooms, eight baths, and a two-car garage.
The building will replace an existing four-story townhouse.

The mansion will host a full-floor master suite, as well as four other spacious bedrooms. It also features a swimming pool, wine cellar, movie theater, gym, spa, and glass elevator. Atop the building will sit a landscaped roof deck, and three additional terraces will maximize the property's outdoor space.

The team purchased the building in 2014 for $9.35 million from industrial designer Karim Rashid, and completion was originally slated for April of this year. However, it seems that the developers have not sacrificed luxury for speed, and plans have moved more slowly than originally anticipated.

Wonder Works has several other projects in-progress, including the Williamsburg condo Oosten, and the Upper East Side condo Vitre.
