Bordering the City of Boulder's permanent greenbelt, this artistic, European-inspired contemporary offers a rare in-town lifestyle defined by privacy, recreation, and open space. Set within a coveted northwest Boulder enclave, it feels like a thousand-acre escape, right in the heart of northwest Boulder, backing directly to protected land with trails and nature as your everyday backdrop. Surrounded by mature trees, native aspens, and thoughtfully curated gardens, the property feels quietly secluded while remaining remarkably connected. Wonderland Lake hiking and biking trails are less than a quarter mile away, while one of Boulder's most desirable private swim and tennis clubs, dedicated to this luxury neighborhood, is just steps from the front door. Designed for modern, active living, the home features clean architectural lines, light-filled interiors, and a contemporary kitchen anchoring open living spaces. Multiple decks and patios-many shaded by mature trees-create exceptional outdoor living, complete with a hot tub, firepit, and generous spaces for entertaining, kids, pets, or simply lounging outdoors. A walk-out lower level with private entry functions beautifully as a guest suite, in-law residence, or independent living space. In addition an artist studio is attached to the oversized detached garage, complemented in the lower level of the home an income producing separate ADU, office, or flex space-ideal for work-from-home, fitness, or creative use. Despite the immersive natural setting, daily conveniences are minutes away, including Lucky's Market and Bakery, walkable schools, and downtown Boulder. This is not just a home-it's an in-town basecamp, where modern design, protected open space, and Boulder's outdoor culture converge.
