The Oskar G. Stonorov House is an historic, American home that is located in Charlestown Township, Chester County, Pennsylvania.

[1] Built in 1938, from the stone walls of an existing stone and frame farmhouse, this historic structure is L-shaped, as was the farmhouse, with frame walls sheathed in cypress.

Designed by its owner, architect Oskar Stonorov, it features large window openings, and a flat roof with parapet or thin edge overhang.

A guest house was added to the property during the early 1950s.

It is located in the Middle Pickering Rural Historic District.
