My "Free Parking" structure. It kind of reminds me of Johnny Rockets. This was loosely based on several parking lot toys I've seen. I often find when stylizing things for "family" based properties, it helps to look not only at real life references, but at really little kids' toys, where they start to abstract down to only the most basic shapes. It makes making the jump to other styles an easier transition, while maintaining it's parking loty essence.
