The Smiths are marine biologists. Their favorite aquatic animals are sharks, so they wanted their home to include their love for sharks in the architecture. The Smiths love to host gatherings with family and friends to talk about their research, so they need a big family room. Because the couple is getting old, they would like a master suite where they can take afternoon naps, as well as a master bath. Their primary care physicians also suggested they do some light exercise, so they also requested an exercise room.
