1520 Baseline Rd, Boulder, CO 80302

About this home

1520 Baseline Road shines as the most impeccably maintained example of early 20th-century residential architecture in Boulder, embodying the design aesthetics and historical narratives of its time, while featuring modern day comforts and systems for the sunniest of dispositions. An absolute gem, this charming 1911-built home is located in the highly sought-after Lower Chautauqua neighborhood, a stone's throw from Chautauqua Park, CU Buffs events and Pearl Street. Newer HVAC and systems throughout, this property seamlessly blends timeless craftsmanship with the most welcoming, cozy ambiance to be enjoyed as it is today. // INSIDE: 9' ceilings, period trim work, built-in cabinetry and leaded glass window accents. Original stained fir wood flooring preserved 30 years under plush carpeting. The spacious, main hallway ladder accesses the immaculate, original wood floor attic with a large north-facing picture window and a beautiful antique furnace. The attic would make a great office or third bedroom with a spiral staircase addition. A huge basement and many closets provide great storage. 1520 is incredibly well built and insulated for the utmost weatherproofing and sound proofing. // OUTSIDE: An inviting front porch welcomes guests. A sprawling 1/4-acre yard is perfectly shaded thanks to mature trees expertly cared for by local Berkelhammer Landscape. An irrigation system and level lot make for an array of gardening opportunities. Seasonal bulbs create secret gardens surrounding the residence. // HISTORY: Exemplary stewards, this home has had only 3 owners. At least two owners have been CU faculty and/or staff, connecting its close ties to the Boulder community. This home is a rare opportunity to own a piece of Boulder's history in one of the city's most coveted neighborhoods, just steps from Chautauqua Park, hiking trails, and the vibrant culture of Boulder. Don't miss the chance to make this historic beauty your own. Contact us today to schedule a private showing!
