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!

As a licensed real estate brokerage, Estately has access to the same database professional Realtors use: the Multiple Listing Service (or MLS). That means we can display all the properties listed by other member brokerages of the local Association of Realtors—unless the seller has requested that the listing not be published or marketed online.
The MLS is widely considered to be the most authoritative, up-to-date, accurate, and complete source of real estate for-sale in the USA.
Estately updates this data as quickly as possible and shares as much information with our users as allowed by local rules. Estately can also email you updates when new homes come on the market that match your search, change price, or go under contract.
