320 S Willson Avenue An 1892 Queen Anne designed by George Hancock, the architect who shaped early Bozeman, holding one of the most coveted addresses on the city's most iconic street. Twice honored with preservation awards, this landmark home pairs its original character - refinished oak and mahogany parquet floors, a wraparound covered porch, southern light through mature trees - with a thorough modern restoration: a gourmet kitchen, a redesigned primary suite, maple flooring upstairs, Pella windows, and updated mechanicals throughout. The main residence offers three bedrooms and two and a half baths across 4, 354 total square feet, with a den/office, formal dining room, and gas fireplace anchoring the main level. Above the rare three-car detached garage, a full 968-square-foot one-bedroom apartment with its own kitchen, laundry, and living room adds genuine flexibility - guest quarters, home office, or income. All of it sits on a lot and a half in the Alderson Addition: nearly a third of an acre of established grounds with a private patio off the kitchen, a firepit, fenced backyard, and off-street parking for an RV. Walk to Main Street in minutes, look up at the Bridgers from your porch, and own a piece of the streetscape that has defined south side Bozeman for 130 years. Properties like this reach the market once in a generation.
