It is a Colonial Revival building with a gambrel roof.","why_significant":"The nomination argues that it represents the early 20th century northward spread of middle-class, multi-family streetcar suburbs along the Lincoln Street corridor. It is also a well-preserved, well-detailed example of the early gambrel-roofed variation of local Colonial Revival three-decker design.","narrative":"Built around 1902 at 18 Ashton Street in Worcester, this three-decker is a multi-family house with a gambrel roof and Colonial Revival detailing. It has a side-hall plan, wood clapboard walls, and wood shingle on the bay windows of the main facade. Modern siding now covers the shingles on the gambrel faces. Features include a recessed entry porch, a bay window with stained glass in its upper light, and a third-floor porch set in a semi-circular gable opening. The house was part of the northern extension of subdivisions along the Lincoln Street corridor on the west slope of Green Hill, a middle-class streetcar suburb north of downtown. Its first owner, Evert Gullberg, was a carpenter who lived in the building. Later owners included a printer and rental-property investors, and tenants were mostly white-collar, supervisory or semi-skilled workers. It was listed as a well-preserved local example of early gambrel-roofed three-decker design and of suburban growth in the area.","period_of_significance":null,"architect_builder":null,"architectural_style":"Colonial Revival (Gambrel) Three-Decker","criteria":["A","C"],"status_note":"Condition is described as very good, with present use as residential; modern siding covers the gambrel faces.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:13:00.847301-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/59/7932/63793259/content/electronic-records/rg-079/NPS_MA/89002388.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/89002388/e8ce57f44a-800.webp","url_1600":"https://nationalhistoricalregister.com/media/89002388/e8ce57f44a-1600.webp","licence":"CC BY-SA 4.0","author":"User:Magicpiano","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:WorcesterMA_EvertGullbergThreeDecker.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:WorcesterMA_EvertGullbergThreeDecker.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/63793259","wikipedia":"https://en.wikipedia.org/wiki/Evert_Gullberg_Three-Decker","wikidata":"https://www.wikidata.org/wiki/Q5417366"},"indexable":true,"url":"https://nationalhistoricalregister.com/massachusetts/worcester-county/gullberg-evert-three-decker-89002388/"}
