Rose Valley Historic District
The pin is a point inside the NPS boundary polygon, not a surveyed location.
Why it's listed
Rose Valley began as a cluster of 18th-century farms and water-powered mills along Vernon Run and Ridley Creek, in the Delaware County hinterland of Philadelphia. In 1901 the Rose Valley Association, led by the architect William L. Price, bought Hutton's Mill and surrounding land, and the community was reorganized around shared paths, a guild hall, and buildings of local rubble stone finished in stucco. Price and his circle built houses of common materials for large and small households alike, producing a unified local look. Architects including William Grey Purcell and Howell Lewis Shay later added modern houses, and the Hedgerow Theatre, which opened in the former mill, became a notable theater. The borough was incorporated in 1923 to preserve the community's separate identity. The district is regarded as an unusually complete record of this utopian experiment and its architecture.
Significance in brief: The nomination argues the district is one of the most important American examples of an intentional community, developed from 1901 by the Rose Valley Arts and Crafts community under William L. Price. It describes the district's buildings as using local stone, stucco and tile in a unified regional vernacular that expressed the community's democratic ideals. It also cites the district's association with Price, its borough incorporation in 1923, and its architect-designed houses into the 1950s.

What listing means for this property
This is a historic district. Buildings within its boundary are either contributing (they add to the district's significance) or non-contributing. Owners of contributing income-producing buildings can claim the 20% federal rehabilitation tax credit; homeowners should look at state credits. National Register districts impose no design review by themselves; a local historic district ordinance, if one exists, does (the difference explained).
General information, not legal or tax advice. Rules change; confirm with your State Historic Preservation Office or a qualified adviser.
