Once-in-a-generation chance to own a Newlands sanctuary backing directly to Mt. Sanitas. On open space - one of only eight homes on 4th St. with this privilege. Tucked up a private, tree-lined drive, the 5,200 sq ft residence sits on a rare 0.6-acre garden oasis framed by apple trees, lavender beds, and the historic Silver Lake Ditch. Inside, light pours through west-facing walls of glass and 20-ft ceilings, capturing ever-changing mountain panoramas. Oak floors run throughout the main level, complementing the warmth of two fireplaces - one in the dramatic living room, another in the cozy library. The flexible layout offers six bedrooms plus an office, highlighted by two king-sized primary suites (one on the top floor, one garden-level with 12.5-ft ceilings, private patio, and separate entrance) - ideal for multigenerational living, guests, or an au pair. Gather in the open kitchen that flows into living and dining areas, spill onto the wrap-around porch for morning coffee under a 60-ft maple, then follow your own gate straight to miles of trail. Evenings bring alpenglow views, cider-press parties with fruit from your orchard, and starlit conversations with a cricket chorus. Secluded yet minutes to Pearl St., Ideal Market, and Boulder's top-rated schools. Newlands is prized for its friendly vibe, where neighbors walk dogs and ride bikes along peaceful, tree-lined streets, gathering for block parties and bonding over a shared love of the outdoors. Homes that touch open space here rarely trade hands. If you've been waiting for privacy, views, and community in one package, this is the opportunity.
