11660 E ALPHA WAY Tucked into Estrella at Mesa del Sol, this 4-bedroom, 3-bath home backs and sides to a retention basin - no rear neighbor, no side neighbor, and mountain views that aren't going anywhere. The private-oasis backyard is enclosed by a full 8-course block wall set from the footer, with a covered viga-column patio and a slider straight out of the primary suite to an additional uncovered patio. The floor plan is clean and unfussy: four true bedrooms, three baths, and a 3-car garage that's fully insulated, drywalled and finished - with a mop sink, water softener, reverse osmosis, insulated overhead doors, and dual openers. What sets it apart is what you can't see. Built to 2x6 exterior wall construction with a full 1" rigid foam wrap under the stucco, R-21 walls, R-44 ceilings, dual-pane Low-E windows and an Energy Star package - specifications that exceed what's going up in this market today. Add to that sunscreens throughout and newly installed plantation shutters for even more efficiency and privacy. Original construction specifications and plans convey to the buyer. Immaculately maintained and truly move-in ready.
