The 1715 log core was built by Joshua Harlan.","why_significant":"The nomination argues the house is a vernacular example of eighteenth century log construction with techniques linked to Swedish colonial log building and English building customs. It is described as the largest, earliest and best preserved log structure in Kennett Township, and Joshua Harlan is cited as one of the first prominent settlers there. The 1947 restoration by Thomas Hooker is documented as retaining original exterior doors, windows and walls.","narrative":"Built about 1715 by Joshua Harlan in Kennett Township, southeastern Chester County, the house is a two story saddle notched log core measuring 26 by 26 feet. In 1814 James Cloud added a two story stone wing on the east side, and a stone and frame addition followed in 1890. The log walls are chinked and stone-filled, and the house has a symmetrical north facade with a center door. Techniques used in its construction are linked to Swedish colonial log building, while its square plan and layout reflect English custom. The house is regarded as the largest, earliest and best preserved log structure in Kennett Township. Thomas Hooker carried out a major restoration in 1947, removing stucco from the log core and rebuilding the chimneys, and the house retains its original exterior doors and windows. Its interior includes Federal-style mantels, moldings and a staircase from the 1814 alterations.","period_of_significance":"1715-1814","architect_builder":"Joshua Harlan (builder of the 1715 log core, per the significance statement)","architectural_style":"Vernacular log construction","criteria":[],"status_note":"Restored in 1947; the form notes the present owners intended to use it as a private dwelling.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:32.443172-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/87001211.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/87001211/9d4e1fc672-800.webp","url_1600":"https://nationalhistoricalregister.com/media/87001211/9d4e1fc672-1600.webp","licence":"CC0","author":"Smallbones","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Harlan_Cabin_Summer.jpg\" rel=\"noopener\">Smallbones</a>, <a href=\"http://creativecommons.org/publicdomain/zero/1.0/deed.en\" rel=\"license noopener\">CC0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Harlan_Cabin_Summer.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71996020","wikipedia":"https://en.wikipedia.org/wiki/Harlan_Log_House","wikidata":"https://www.wikidata.org/wiki/Q5658358"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/chester-county/harlan-log-house-87001211/"}
