This Week's Find: Bethesda's Mushroom House

Bethesda’s Mushroom House hit the market late last week, and it can be yours for $1.2 million.
The house — alternately referred to as the “Flintstones House,” the “Smurf House” and the “Hobbit House,” per Bethesda Magazine — sits on Allan Road less than a block from the DC/Maryland line (map).

The home was purchased by Edward and Frances Garfinkel in the ’60s. The Garfinkels set about taking what was a “staid, conventional house” and turning it into something more whimsical with a bold addition, according to a 1974 article in The Washington Post. The home was designed by Roy Mason, “the marshmallow architect,” per The Post, and crafted out of polyurethane.

Building the foam addition wasn’t easy; it cost more than double what the Garfinkels budgeted, and along the way there were mishaps, including the accidental spraying of a neighbor’s car with foam.
Here are the details and a few more photos:
