Backyard Workroom opened an assembly plant in the Richardson Innovation Quarter at 715 N. Glenville Drive, Ste. 430, Richardson, on Nov. 18. The startup was founded by builder and entrepreneur Eric Benavides, who created a prefabricated workroom kit that allows users to build their own modular shed in just a few hours. The kits include three styles, four color schemes and six door colors from which customers can choose. The 10-foot-by-10-foot sheds are made from plywood and steel and require no carpentry or electrical skills for assembly. 469-400-9500.
