Nestled in the heart of Boulder's tree-lined Whittier neighborhood, where picket fences and mature trees frame historic homes, this beautifully maintained residence blends classic charm with modern functionality. The interior layout balances the historic aesthetic with a modern lifestyle. Warm, wood-trimmed windows, wood floors, and a custom fireplace in the sun-soaked living space allow for large gatherings, while the nooks and an office/dining room off the main living area offer increased optionality. Kitchen opens to the outdoors with a wall of glass sliders. Incredible cabinet storage, walk-in pantry, and oversized center island make every day an entertaining day! With six bedrooms and six baths, there are layout options for everyone. Main-level primary suite, with both an en-suite bath and in-closet laundry, tucks in behind the kitchen. Upstairs in the main home are three bedrooms, two oversized and two with en-suite baths, one w/ a south-facing balcony. The beautifully finished lower level offers exceptional flexibility with high ceilings, deep window wells, two bedrooms, a full kitchen, a full bathroom, a washer/dryer, and a separate entrance via a backyard staircase. Detached, two-car garage with alley access and overhead storage. Beyond the garage, a large parking pad accommodates up to four additional cars, RV, or outdoor equipment. The garage structure includes a versatile bonus space with a kitchenette and half bath, perfect for a home office, artist's studio, workout room, or recreation area. The backyard is designed for both entertainment and relaxation, featuring a spacious patio, fire pit, and mature landscaping that enhances the serene atmosphere-perfect for those who value privacy and indoor/outdoor living. With a backup generator, a concrete-finished crawl space under the garage, and optimized storage and parking-rare features in historic properties-this is more than a home; it's a thoughtfully designed retreat brimming with possibilities!
