About 661 Maxwell Avenue

A rare find in Mapleton Hill! Beautifully remodeled down to the studs in 2020 and complemented by a brand-new $1,000,000 ADU, this unique home brings together historic charm, gorgeous modern finishes and exceptional flexibility. Filled with natural light, the home offers an inviting flow with spaces that feel both connected and comfortable. Exposed brick adds warmth and character, while hardwood floors and thoughtfully chosen finishes create a cohesive feel throughout. The custom kitchen is a standout, featuring Wolf appliances, a Sub-Zero refrigerator and a charming built-in corner table-the perfect gathering spot for morning coffee or a casual meal. The main level includes a spacious study, a bedroom, a full bath and a powder room, providing wonderful options for guests and working from home. An elegant staircase with custom treads and metal detailing leads upstairs to the primary suite, where a generous deck captures foothill views and beautiful sunsets. It's a lovely place to start the day or unwind in the evening. The walkout lower level expands the living space with a recreation room, two additional bedrooms and a three-quarter bath, offering room to spread out and host guests comfortably. Adding to this exceptional property is the brand-new ADU with high end finish, bringing another dimension to the home's versatility and appeal. Walk to the Mount Sanitas trails for a morning hike or head to Pearl Street for shopping, dining and all the energy of downtown Boulder. With its blend of timeless character, modern comfort and a coveted Mapleton Hill setting, 661 Maxwell captures the best of Boulder living and with the Sundance Film Festival coming to Boulder in 2027, this location offers even more to look forward to. The main house is 3048 sq ft. ADU 1063 with a separate entrance basement 576 sq ft (great for storage!)
