Bradley on a nearly 6-acre hilltop site.","why_significant":"The nomination argues the house embodies the character-defining features of Charles Adams Platt at the peak of his career, and is the only such example in Massachusetts. Its inset loggia is rare in Platt's work and may be unique among surviving Platt houses. It is also a representative early 20th-century suburban estate tied to the Sears and Bradley families.","narrative":"Oakcrest, at 60 Sears Road in Southborough, Massachusetts, is a 34-room country house of about 15,000 square feet, designed in 1913 by Charles Adams Platt. Built of stucco over brick, it has a 2-½ story central block flanked by two-story ells, a slate roof, and a Corinthian-columned entrance. Inside, a long central hall leads to a recessed loggia, a walnut-paneled library, and herringbone floors. Sarah Choate Sears built it as a wedding present for her daughter Helen and J.D.C. Bradley, near the family's existing country house. It was listed for architecture. Platt, then at the height of his reputation, was known for symmetry, restraint, and the blending of indoor and outdoor space. The inset loggia is rare in his work and may be unique among surviving Platt houses. Later changes included a school's use of the house and the enclosure of the loggia, though the main exterior and landscape features remain.","period_of_significance":"1913-1948","architect_builder":"Charles Adams Platt, architect","architectural_style":"20th Century: Colonial Revival","criteria":["C"],"status_note":"Still in use as a dwelling; the loggia was enclosed in the 1970s, and the library bookcase alterations of the mid-1980s were reversed in 1994.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:13:04.977945-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/70/7971/63797170/content/electronic-records/rg-079/NPS_MA/99000260.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/99000260/d5961272d4-800.webp","url_1600":"https://nationalhistoricalregister.com/media/99000260/d5961272d4-1600.webp","licence":"CC BY-SA 4.0","author":"User:Magicpiano","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:SouthboroughMA_JDCBradleyHouse.jpg\" rel=\"noopener\">User:Magicpiano</a>, <a href=\"https://creativecommons.org/licenses/by-sa/4.0\" rel=\"license noopener\">CC BY-SA 4.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:SouthboroughMA_JDCBradleyHouse.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/63797170","wikipedia":"https://en.wikipedia.org/wiki/J.D.C._Bradley_House","wikidata":"https://www.wikidata.org/wiki/Q6104024"},"indexable":true,"url":"https://nationalhistoricalregister.com/massachusetts/worcester-county/bradley-j-d-c-house-99000260/"}
