CASE STUDY HOUSE #21 Pierre Koenig designed Case Study House #21 in 1958. It was originally completely surrounded by water, with a walkway and driveway spanning the moat at the front door and carport, respectively. The house was severely messed with over the years, but restored in the '90s with help from Koenig. Mapped: The Case Study Houses That Made Los Angeles a Modernist Mecca - Curbed Maps - Curbed LA
