We feel very strongly that we have one of the most efficient and well-rounded teams in the local building industry.

Bill Lemon Jr. – Owner/Operator

A second generation builder, Bill grew up working with his father and always had a passion for woodworking and operating. He branched out on his own when he was 24, literally building out of the back of the family car, and has since developed Custom Design Builders into one of the premier residential building companies in the area. Bill’s ability to visualize, develop, plan, and construct projects are instrumental in the building process. His work ethic and dedication to his craft and customers is unmatched, leading to the reputation that he has achieved.

Bill Lemon III – Operations Manager

A third generation builder, Bill III grew up playing on job sites and working small jobs for his father. As he grew older, he began working on school vacations and joined the team full time in 2002. Since then, responsibilities have included overseeing job operations, project development, marketing, and financial management.


Custom Design Builders provided invaluable guidance and support throughout our 6 month renovation of a 1950s ranch.  They respectfully provided insightful and thoughtful design solutions based on their wealth of experience in the business that built on and enhanced our own ideas and family needs.  When issues came up, they were great about bringing them to our attention with two or three recommendations for us to consider, keeping both our budget and our desires in mind. They were very flexible with us and a pleasure to work with from demolition to design through finishing touches.  I would highly recommend them.

Their workmanship throughout the house was and is breathtaking – to see the creativity and ideas brought to life from the blueprints was a very exciting experience.  Bill Jr. has a knack for knowing exactly how to mix efficiency and functionality in a room, while bringing a creative, craftsman essence to the home.
