Franklin H. Karn built this house in 1937 for his daughter Mildred and her fiancé, Wendell Turner. Mildred had seen a similar one which she liked in Washington, D.C. Period features, combined with clean modern lines, reflect Rockville's growing sophistication as it evolved from a small county seat to a more urban community.

The dark brick house has distinct Tudor features: jutting gables, stone quoining around the entry, and an arched brick garden entry. Over the front door is a limestone lintel, carved by stone masons into a shell and foliage pattern. With interior mouldings of chestnut wood, this house must have made quite a stunning wedding gift

Karn was a custom builder. In addition to this house, he built 115, 119, and 18 Forest Avenue and other homes and schools in the Rockville area. His son and grandson later joined the business. The Karns lived at "The Maples," a farm on Great Falls Road, now Rose Hill Falls subdivision. From 1934-38, Karn served as a Montgomery County Commissioner.

The Turners remained in the three-bedroom house until 1958. Current owners are Hal and Maggi Osgood.
