Iconic Minnesota 'Mushroom House' With Curved Walls, Domed Ceilings, and a Sunken Living Room Lists for $370K

June 1, 2026 - 04:42

A one-of-a-kind home in Minnesota, often called the "Mushroom House," has just been listed for $370,000. Built in 1970, the structure was made using sprayed polyurethane foam, a method that gives it its signature rounded walls, domed ceilings, and an unusual, organic shape that stands out from any traditional house on the block. The property is now considered one of the only foam dome structures still standing in the United States.

Inside, the home feels like stepping into another era. The living room is sunken, with a curved layout that follows the building's natural lines. Large windows let in plenty of light, and the overall design feels open and sculptural rather than boxy. The kitchen and bedrooms also follow the same soft, rounded aesthetic, with no sharp corners or standard right angles.

The current owners have worked to preserve the original character while updating some systems. Real estate agents describe the home as a true piece of architectural history, noting that few homes like it were ever built, and even fewer remain intact. For buyers looking for something completely different from a standard suburban house, this listing offers a rare chance to own a slice of 1970s experimental design. The asking price of $370,000 is considered reasonable for the area, especially given the home's unique construction and historical value.
