Broad Margin is a private residence in Greenville, South Carolina. The house was designed by Frank Lloyd Wright and was built in 1954.[2][3] It is one of two buildings designed by Wright in South Carolina (the other being the Auldbrass Plantation).

It was named to the National Register of Historic Places in 1978.[1]

The house is built into the slope of the 2-acre (0.81 ha) lot. It has 12-inch-thick (30 cm) concrete walls. It extensively uses cypress wood throughout including its ceiling of cypress boards. The house has polished red concrete floors. Copper tubes are embedded in the concrete floors to heat the house using hot water.

The cypress furniture was designed for the house. The doors and window frames were constructed on-site of cypress. The hardware is solid brass.

The house was documented with photographs and written historical data by the Historic American Buildings Survey in 1988.[4]
