It is built partly over a waterfall on Bear Run in the Mill Run section of Stewart Township, Pennsylvania. The house was designed to serve as a weekend retreat for Liliane and Edgar J. Kaufmann, the owner of Pittsburgh's Kaufmann's Department Store.

The Ohiopyle High Bridge is a structure that carries the Great Allegheny Passage trail across the Youghiogheny River in Ohiopyle, Pennsylvania. The span was originally opened in 1912 as part of the last major railroad constructed in Pennsylvania. It served the Western Maryland Railway's expansion from Cumberland, Maryland to Connellsville, Pennsylvania and was one of two bridges to cross a meandering section of the Yough in Ohiopyle. The High Bridge rises over 100 feet higher than its sister span, which sits upstream from the area's famous waterfall. By the 1960s, the importance of the High Bridge was dramatically reduced. In 1975, the Western Maryland eliminated all service west of Hancock, Maryland. Following the closure of the line, the bridge sat unused until its repurposing as a pedestrian and bicycle crossing in 1999.

The Ohiopyle Highway Bridge is a structure that carries two lanes of Pennsylvania Route 381 Youghiogheny River in Ohiopyle, Pennsylvania The span, which opened in 1975, is the third to be located in the vicinity. An original 19th-century covered bridge was replaced by a Pratt truss bridge around 1900. Because of a low-clearance underpass located directly adjacent to its southern approach, this structure proved to be obsolete once the automobile replaced the train as the primary method of tourism in the years following World War II. Although already scheduled for replacement, the discovery of a major fatigue crack sealed the fate of this structure, leading the way for the present girder bridge to be erected.
