Thunderbird Lodge is a building of historical and architectural significance in the utopian community of Rose Valley, Delaware County, Pennsylvania.

In 1904, architect William Lightfoot Price converted an existing circa-1790 stone barn into studios for the artists Charles H. and Alice Barber Stephens.

Appended to this, he designed a rambling fieldstone-and-stucco house, including a 3-story octagonal stair tower that joined the wings and served all five levels.

The fireplace that Price designed for his studio is in the silhouette of a Thunderbird, a symbol that also appears on the building's exterior in Henry Mercer’s Moravian tiles.

[8] At the edge of the property, along Rose Valley Road, is a 1926 Pennsylvania State historic marker, commemorating an important Native American trading route, the Great Minquas Path, that ran nearby.
