Historic builder/architect duo Lyle Rowley and Jack Wilson built this impeccable Ju-Nel midcentury modern in 1961. It has been lovingly preserved with original architectural J-N elements such as exposed beams, vaulted ceilings, original cabinets, and slate floors. The 1,718-square-foot home has three bedrooms, two bathrooms, and two living areas built around a treed, landscaped courtyard. Ed A. Murchison for Virginia Cook Realtors, 972-381-6415.
