Structure and Design

Building a custom home involves not only the structural elements, but the aesthetic choices as well. And no one understands style, color, fabric and space planning better than Bonnie Stromberg, Tracy’s wife and business partner. As an interior designer at Selden’s furniture, Bonnie brings more than 20 years of design experience to each project. She’ll serve as your room-by-room Style Guide, helping you decide  furniture layouts, paint choices, window coverings, flooring and accents.

Tracy built his own residence in Crystal Creek Estates
