About this home

Public Remarks: A rare chance to own a piece of history! This classic Victorian Farmhouse is one of Boulder's first (circa date 1898) and it's character and charm have been meticulously maintained throughout. Included is a recently restored barn thoughtfully transformed into a legal ADU (accessory dwelling unit) offering unlimited possibilities for both personal use and monetary gain. This home represents the lifestyle of a treasured bygone era, but includes all the modern conveniences of today. Features include 9' ceilings, beautiful woodwork throughout, expansive eat-in kitchen, and an open floor plan. The beautiful and private lot offers numerous outdoor living spaces including an inviting front porch, a multi-season wrap-around back porch/deck, and a flowing patio set-up for gracious entertaining, gardening and relaxation. All this while just around the corner from the offerings of Pearl Street and the best the Boulder area has to offer nearby by foot, bike, bus, or car.
