It is unaltered in its original site, though numerous additions are evident.","why_significant":"The nomination argues the house is unique to the Pittsburgh area because it is a catalogue of mid-nineteenth-century architectural revival styles, combining Greek Revival, Gothic Revival, Italianate and possibly Eastlake ornamentation on a traditional cottage. It notes that mid-century builders' handbooks popularized the Picturesque and made these styles available to common builders. The additions illustrate a common practice in American vernacular architecture.","narrative":"Built around 1864 as a modest one-and-a-half story, five-bay wood frame house with chimneys at either end, the Gardner-Bailey House in Edgewood Borough, Pittsburgh, is notable for the way its owners and builders layered architectural revival styles onto a traditional colonial plan. Its pedimented gable and acroteria recall the Greek Revival, its projecting central gable forms a slight T-plan associated with the Gothic Revival, and its double-arched door panel, paired eave brackets and belvedere are Italianate. A full-width verandah carries pierced braces and Italianate console brackets, and the carpenter's Gothic balustrades and ridge cresting may be Eastlake. Mid-century builders' handbooks made such Picturesque ornament widely available, and the house is regarded as a clear example of that trend. Its later additions, including the porch, belvedere and enlarged central window, are visible in the building fabric, which is why it is considered significant for its architecture.","period_of_significance":"c. 1864","architect_builder":null,"architectural_style":"Colonial wood frame house with Greek Revival, Gothic Revival, Italianate and possibly Eastlake features in the mid-century Picturesque tradition","criteria":["C"],"status_note":"Condition marked excellent and unaltered; original site","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:30.874788-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/74001739.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/74001739/952441dfb6-800.webp","url_1600":"https://nationalhistoricalregister.com/media/74001739/952441dfb6-1600.webp","licence":"Public domain","author":"User:Nyttend","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Gardner-Bailey_House.jpg\" rel=\"noopener\">User:Nyttend</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Gardner-Bailey_House.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71997646","wikipedia":"https://en.wikipedia.org/wiki/Gardner-Bailey_House","wikidata":"https://www.wikidata.org/wiki/Q5522575"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/allegheny-county/gardner-bailey-house-74001739/"}
