The Smith family, who enjoy weekends spent with their sports cars, are planning to expand their living space with a grand family room, a private gym, and a master suite. They believe their house doesn't reflect their shared passion and want to incorporate their shared passion, which is based on one of Mr. Smith's prized possessions, into the design. The grand family room will accommodate not only their family but also friends who are car enthusiasts. To escape the loud conversations and videos in the family room, they have requested a master suite. Mr. and Mrs. Smith have also requested an exercise room and a rooftop with an awning for barbequing and other outdoor activities.
