Source-derived summary

The Edward R. Hills House, also known as the Hills–DeCaro House, is a residence located at 313 Forest Avenue in Oak Park, a suburb of Chicago, Illinois, United States. It is most notable for a 1906 remodel by architect Frank Lloyd Wright in his signature Prairie style. The Hills–DeCaro House represents the melding of two distinct phases in Wright's career; it contains many elements of both the Prairie style and the designs with which Wright experimented throughout the 1890s. The house is listed as a contributing property to a federal historic district on the U.S. National Register of Historic Places and is a local Oak Park Landmark.

Editorial analysis

Why this record matters

The subject matters to the places & architecture register because the source frames it as historic house in Oak Park, Illinois. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Sep 4, 2026. The first chronological checks are 1906.

Critical limits

A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Treat names, boundaries and functions as historically changeable. Maps, plans, inventories and administrative records can clarify what the place meant at different dates.
