There are homes that shelter people, and there are homes that reflect them. This home is the second kind. Known locally for more than fifty years as the "Mushroom House" or "Flintstone House," this architecturally iconic triple-dome home was built in 1970 by Duluth developer George Hovland and designed by architect Stan Nord Connolly using an innovative foam-shell construction method. Tucked into a private, wooded 0.60-acre lot in Kenwood, the setting feels hidden away while remaining walking distance to the University of Minnesota Duluth and the College of St. Scholastica. Inside, the home unfolds with curved walls, soaring dome ceilings, and spaces that feel more sculpted than built. The main level features a sunken living room with built in sofa and a dramatic wall of seven-foot patio doors leading to the wraparound deck overlooking the trees. The arched kitchen includes a breakfast bar area and carries through the organic geometry that makes this home unforgettable. The primary bedroom offers vaulted ceilings and epoxy flooring, while a second bedroom and three-quarter bath complete the main floor. The walk-out lower level opens into a spacious great room with beamed ceilings, a wood-burning fireplace, and patio access to the wooded backyard. Three additional bedrooms, a full bath, half bath, and laundry room create flexibility for anything you need. A two-stall attached garage with loft storage adds practicality to a home that is anything but ordinary. Meaningful improvements have already been made for the next owner. In 2021, the primary bedroom and lower level family room received epoxy flooring throughout, new carpet was installed in the lower-level bedrooms and the upper office, the sewer lateral was replaced, and a full-house dehumidifier and whole-home ozone air scrubber were added. In 2022, the exterior was professionally repainted with UV-resistant paint and all skylights were sealed. In 2024, all 16 windows were replaced. This is not a home for someone looking for ordinary. It is for someone drawn to architecture, creativity, privacy, and spaces with a story to tell. Homes like this rarely become available. And once you walk through it, you will understand why.
