This four-level penthouse apartment in New York has some quieter moments (to contrast with the multistory reflective slide snaking throughout). Designed by architect David Hotson_Architect with interiors by Ghislaine Viñas, this top-floor bedroom is a minty moment of repose. Set into the dormer at the opposite side of the bedroom, the alcove bed occupies a wedge of space extending up to the attic-level oculus window. Photo: David Hotson. Courtesy of David Hotson.
