This immaculate, original condition mid-century modern ranch home was designed by William "Billy" Smull & constructed in 1951. A well regarded modernist Architect, Mr. Smull spent the 40's & early 50's designing modern developments throughout the D.C. Metro area before relocating to NYC. All of the original design elements remain fully intact in this one-owner home! Sited at the end of a cul-de-sac (Randall Road was named in honor of their Son), this is the largest lot on the street at just over 1 acre. Tucked into the hillside, the unassuming front fa ade belies the open concept design and walls of glass windows facing the private rear yard with a Koi pond, greenhouse & flagstone patios. Vertical v-groove siding (either redwood or Cedar) is replicated in the entry foyer, hiding the closet & kitchen door. A direct sight line out to the rear yard is evident the moment you enter the home, flooding the living areas with light (including through several skylights). Flagstone & concrete floors provide a simple surface for specimen rugs while the angled ceilings rise slowly to the rear walls of glass & over-sized French doors. A floor to ceiling stone fireplace flanks one entire wall of the living area, while access to the attached greenhouse is through the dining room. The v-groove siding continues around the corner to a pass-through window into the efficient galley kitchen as well as an original floating buffet in the dining room. The original kitchen remains and has a bank of windows overlooking the side yard & patio, access to the laundry room and a rear door to the carport. Down the private hallway to the bedrooms, one will find two bedrooms facing the front yard & a hall bath. A large storage closet is in between the 2nd & 3rd bedrooms while the efficient master suite has a walk-in closet, an en-suite bath and direct access to the rear yard. In 1965, the Owners commissioned an expansion of the house by incorporating a massive Art studio off the rear corner of the house with vaulted ceilings, another patio facing the rear yard & transom windows for natural Northern light. This is manageable one-floor living at its best, with exceptional original details and an un-touched canvas to create your future visions for the property. This is not your typical cookie-cutter home. Come discover an "original" Smull design, and dream of making it your own!
