The tiny house trend, in which homeowners learn to live in a streamlined space with minimal possessions, has been alive and well near Friendship Heights for decades.

A 315-square-foot brick single-family home at 4905 River Rd. in Bethesda started life as a Pepco substation but has been a private residence since 1980. Today, the one-room home is listed for sale at $475,000.

The home, which rests on a 1,848-square-foot lot, could be ideal for anyone fascinated with the idea of living in a former Pepco substation with super-thick walls and floors or a streamlined lifestyle.

The brick home has 16-inch concrete slab steel girders supporting 22-inch-thick brick walls and a slate roof. The structure was built to keep people away from the electrical transformers inside then sold as a home when Pepco needed a larger space. A chain-link fence still surrounds the home, which has a gravel driveway and space for parking.

The home on the corner of River Road and Willard Avenue is less than one mile from the Friendship Heights Metro station and dozens of shops and restaurants. The kitchen has a stove, a refrigerator, a sink and a stacked washer-and-dryer, plus cabinets for storage. The main room combines a living area and office space and has a full bath. Steps lead up to a loft bedroom and closet.
