Inside, there’s an inviting entrance hall, a huge great room, a dining room, a kitchen, a bar, five bedrooms and four bathrooms, all of which are decorated with neutral tones and raw materials, such as concrete, wood and terracotta. From unique furnishings to built-in cabinets, every room benefits from something beautiful to look at. Unsurprisingly, the one-of-a-kind home was added to the National Register of Historic Places in 1972, meaning it's protected from architectural changes.
