Tucked into the coveted Cattail Creek neighborhood, 3376 Fen Way is a 2020-built contemporary with warmth in all the right places - and a rare income-producing ADU that makes it one of the most versatile offerings on Bozeman's northwest side. The main residence opens to a light-drenched floor plan where oversized windows frame mountain views from nearly every room. Polished concrete floors and clean architectural lines give the space a modern edge, balanced by rich wood trim, solid wood doors, and the quiet luxury of high-efficiency radiant in-floor heat underfoot. The kitchen anchors the main level with quartz countertops, custom tile, and stainless appliances, flowing seamlessly into the dining and living areas. A main-floor bedroom, half bath, and dedicated laundry round out the level, while upstairs you'll find the primary suite alongside two additional bedrooms and a second full bath. Above the attached garage, a private 728 square foot one-bedroom ADU delivers serious optionality - complete with its own full kitchen, living room, full bath, and laundry. Whether you're looking at long-term rental income, a Bozeman short-term stay, a guest retreat, or multigenerational living, the ADU is a legitimate asset, not an afterthought. Step outside to a fully landscaped yard with underground sprinklers and a covered patio built for long Montana evenings. The location is quintessential Cattail Creek: seconds from the neighborhood's parks, ponds, and trail network, with Gallatin High, Chief Joseph Middle, and the shops and restaurants along Baxter and Oak all just minutes away. New construction quality, mountain views, and a turnkey ADU - all inside Bozeman city limits. Homes like this don't sit.
