If you’re sick and tired with the small condos in San Francisco, and you still got some cash on hand, here’s some inspiration from the creative folks at Joel Sanders Architect who recently gave this downtown duplex penthouse a modern facelift. So what exactly makes it so interesting other than its location and the amazing views? Let’s start with the two living zones. A darker inner one where natural materials are predominant (walnut paneling and banquettes upholstered in deep blue mohair), and the bright part of the duplex, with the living/media room and the kitchen/dining area on the first floor, along with the master bedroom suite on the second floor. Definitely a five star.
