    CHAUTAUQUA MID-CENTURY MODERN RANCH A rare blend of location, livability and luxury. LOCATION -- Rebuilt from the studs up in 2005 and significantly renovated in 2019, our 2,640 square foot single-level house is on a peaceful, winding block with great neighbors. -- Five houses west of us, Mariposa Avenue dead ends at the McClintock Trailhead just below Chautauqua Park, whose trails and attractions are our “backyard.” -- You can easily walk to the university. You can even walk to town. LIVABILITY -- From the street, there is one step to go up into the house if you walk by the garage. No basement. No attic. No trudging up and down stairs. No paying for unused space. -- The .32-acre lot has beautiful, mature, park-like landscaping and hardscaping on all four sides. There is no grass to mow. Everything is irrigated. -- The four bedrooms have flexible uses. We use three of them as two offices and a den that converts to a guestroom. The library can serve as a den or office. -- There is underfloor, radiant heat throughout the house plus a back-up furnace and A.C. -- Large overhanging eaves surround all the living areas, shading and cooling in the summer. We have not used the A.C. since 2012. -- 24 solar panels on the roof produce approximately 10 megawatts annually, completely offsetting our electric bills including charging 2 electric cars. EV charger in garage. -- The house is set back from the street and well insulated from what little street noise there is. LUXURY -- The kitchen and three bathrooms feature high-end granite and top of the line fixtures. -- The closets, bedrooms and bathrooms have custom, built-in cabinetry, shelves and drawers. -- The house readily accommodates the hanging and display of fine art and collectables. The feel of our home is an extraordinary combination of elegance, warmth, color and comfort. As long as you live in Boulder, you will not need to buy another house.
