Take a break from the happy cacophony of Hollywood with the architectural equivalent of a juice cleanse. The Schindler House was designed by Vienna-born Rudolf M. Schindler, whose employer Frank Lloyd Wright inspired his modern design aesthetic. A flat concrete slab serves as the base for this imaginative duplex, which was intended to accommodate two young couples. With its open floor plan and relatively tight living quarters, it’s a marvel of a place (and it’s free to walk through on Fridays from 4pm to 6pm). Ponder whether you could share 3,500 square feet with three other people as you wander.
