Unparalleled. Shanidiin Farm is a rare 40-acre sanctuary offering the ultimate in privacy, views, understated elegance, and sustainable design-all just 10 minutes from downtown Boulder. Named for the Navajo word meaning "ray of light," the estate lives up to its name in every detail. Thoughtfully oriented and masterfully designed, the home captures light, filling interiors with warmth while framing sweeping views of the Flatirons and back range. Bordering Open Space, the property feels infinite, a private world of its own where land, sky, and architecture converge. Designed by Gettliffe Architecture and brought to life by master builder Harrington Stanko, Shanidiin Farm is a triumph of detail and intention. Walls of windows dissolve the boundaries between indoors and out, while polished concrete floors, soaring ceilings, and natural finishes create an atmosphere both grounded and radiant. No element of comfort or sustainability has been overlooked. Geothermal and solar systems, radiant floor heating, and central air conditioning ensure year-round efficiency and ease. Luxurious guest suites, each with en suite bath, provide privacy and comfort. Every aspect of construction reflects an unparalleled commitment to quality, from the placement of windows that capture morning light to the seamless integration of high-performance systems.The property also includes 96 shares of North Boulder Farmer's Ditch and cisterns providing 35,000-gallons of water storage for abundant irrigation. A substantial recreation "studio" offers endless possibilities be it world-class gym, spa, conference space, or creative retreat-complete with sauna and steam shower. Car collectors will value space for a 6-car garage with ATV compatibility. Evenings shine around the cowboy cauldron, perfect for campfires, stargazing, and creating memories. Shanidiin Farm is a generational sanctuary and modern work of art, unlike anything else in Boulder. LIVE BOLDER, LOVE BOULDER!
