Experience urban sophistication at the base of Mt. Sanitas in this stunning custom-built green home. Located in the highly sought-after Newlands neighborhood, this residence features a striking modern facade and bright, open living spaces designed to celebrate its premier location. Backing directly to protected open space, the property offers a rare personal sanctuary with world-class trail access right outside your back door. The interior is defined by high-quality finishes, gleaming hardwood floors, and thoughtfully placed oversized windows that flood the home with natural light while showcasing serene treetop views. The heart of the home is the upper level, where a chef-inspired open kitchen, dining area, and living room merge into a singular expansive space with spectacular views that transition effortlessly to the tranquil outdoor setting. The top-floor living areas offer a unique treehouse feel, opening seamlessly to a large deck and buff sandstone patios for high-end indoor-outdoor entertaining. In the backyard, the Silver Lake Ditch meanders through the patio and yard space, creating a soothing natural soundtrack that transitions beautifully into the foothills. The primary suite serves as a spa-inspired retreat with a five-piece bath and steam shower, while a dedicated rec room provides custom built-ins and an integrated television for relaxation. While the home feels remarkably private, it is perfectly positioned near Boulder's most popular hotspots. You are just steps from the Goat Trailhead and a short stroll from the expansive North Boulder Park. Convenience is at your fingertips with the Ideal Market shopping center nearby, home to local favorites like Santos, Sweet Cow Ice Cream, and Beleza Coffee. Plus, the iconic dining and shopping of the Pearl Street Mall are only minutes away, offering the ultimate Boulder lifestyle.
