Located downtown in the historic Townsite neighborhood at the base of Mars Hill, directly across from Thorpe Park -- a 2019 architect-designed build in a neighborhood where new construction is uncommon. Steel moment frame, weathering-steel panels and expansive glazing, metal roof, R-38 spray-foam envelope: new-construction performance within walking distance of downtown's restaurants, the Sunday farmers market, and Lowell Observatory.The entire top floor is the primary suite- bedroom, en-suite bath, walk-in closet, window seat -- opening onto an 890 SF private rooftop deck with a covered outdoor room, gas fireplace, and kitchenette with dishwasher. By day the deck looks over downtown to Mount Elden. By night it's a private observation deck in the world's first International Dark Sky City: marshmallows over the fire, a glass of wine, and the stars Lowell Observatory was built on this hill to see. The home faces open ponderosa woods across the street rather than another house, and the neighborhood's resident deer make regular morning appearances -- easiest to watch from the main-level living room with coffee and the fireplace going. That room rises two stories under a vaulted ceiling, with hardwood floors and windows placed for all-day natural light, and opens to a kitchen with quartz counters, induction cooktop, island, and walk-in pantry. A dedicated office with closet serves as the fourth bedroom; mudroom and powder bath sit off the garage entry. The second level holds two bedrooms, a family room, a flex room, full bath, laundry, a balcony, and a planted roof garden. Thorpe Park's 219 acres are a two minute walk -- disc golf, tennis, ball fields, dog park, and Frances Short Pond -- with Flagstaff Urban Trail System access from the park to Mars Hill, the observatory trails, and downtown. Lowell Observatory and its new Astronomy Discovery Center are up the hill. Dinner on San Francisco Street is a walk home under the same dark sky. Engineered for 7,000 feet: air conditioning (rare in Flagstaff), two-furnace heating with separate zones for the downstairs and upper floors, heated gutters, a south-facing driveway, tankless hot water, Flo by Moen whole-home leak detection with automatic shutoff, and Ethernet to every room. Two-car garage off the paved alley plus two additional parking areas; dry crawlspace for gear storage.
