Perfectly positioned close to North Boulder Park, Ideal Market, and Pearl Street's renowned restaurants and shops, it offers the ultimate Boulder lifestyle with easy access to hiking, biking, and endless outdoor adventures. Step into a sun-drenched living space where beautifully refinished maple hardwood floors lead you through a thoughtfully designed floor plan. The bright, airy south-facing family room opens to a custom kitchen featuring crystal maple cabinetry, slab granite countertops, custom tile work, a Wolf cooktop, and a Miele oven and dishwasher. The home features three upstairs bedrooms. The primary bedroom has a private deck for reading on lazy Sunday afternoons in an Adirondack chair. The upstairs three-quarter bath has a sizeable walk-in river-rock shower, while the main floor offers a full bath with modern finishes. Fresh interior paint enhances the home's warm, inviting atmosphere. The true showstopper of this property is the meticulously landscaped outdoor space, designed by the landscape architect owners to be a tranquil retreat. Professionally installed rock gardens, mature trees, vibrant flower beds, and flagstone walkways create a lush and private oasis. A spacious flagstone patio is perfect for entertaining or simply unwinding. Adding to the home's versatility is a detached 389 sq. ft. artist studio with vaulted ceilings and both 110V and 220V power-ideal for a creative workspace, home office, or potentially a guest suite or ADU. So close to Sanitas and Dakota Ridge trailheads, world-class outdoor recreation is at your doorstep. Whether strolling to Sweet Cow for ice cream, grabbing coffee at Belleza, or exploring Pearl Street's boutiques and nightlife, this home's location is unbeatable. Don't miss owning a piece of Boulder's history while enjoying all the conveniences of modern living. Welcome home!
