Experience the pinnacle of Boulder living in this sun-drenched Victorian sanctuary, perfectly positioned on an expansive 0.22-acre lot in the heart of iconic Mapleton Hill. Tucked behind a lush canopy of mature trees, this residence offers a rare sense of seclusion and scale just steps from the Mt. Sanitas trailhead and the world-class dining of Pearl Street. The main home radiates historic charm, featuring soaring ceilings and oversized windows that bathe the multiple living areas in natural light. The south-facing sunroom is a morning highlight, providing a serene space to sip coffee while overlooking the grounds. With 3 bedrooms and 2 bathrooms, the current layout is both comfortable and gracious, yet the deep lot offers an incredible canvas for those looking to reimagine the space with a primary main-level suite or a high-end modern addition. Adding to the property’s exceptional value is a detached 1-bedroom, 1-bathroom guest house. Complete with its own private patio and an active rental license, this versatile space is perfect for an income-producing long-term rental, a high-end home office, or a private retreat for visiting guests. Rarely do you find a Mapleton Hill property that combines a private driveway, a massive backyard, and an additional legal dwelling unit. Whether you’re walking to a neighborhood cafe, hitting the trails, or exploring the vibrant downtown core, this is a once-in-a-generation opportunity to own a piece of Boulder’s most storied neighborhood.
