Designing interiors for the Chateau was Shawn’s first collaboration with hotelier Andre Balazs, a partnership that endures two decades on. Having grown up visiting this Hollywood icon, the project was a labor of love for Shawn. With a devoted following anxious to preserve the spirit of the space, Shawn sought to tread a fine line between updating and preserving the design. The Chateau's fans were not disappointed. Architectural Digest praised how “Hausman came up with a layered look, mixing furnishing of different styles and periods” to convey the building’s storied past and craft a feeling of luxury both nuanced and understated. Attesting to the timelessness of the design, Condé Nast Traveler named it to their 2015 Gold List of “100 hotels that change the way we see the world.” Shawn continued to be involved with the hotel's design, returning to update the lobby and the lobby bar.
