Trethewey House Heritage Site

Our drop-in tour hours are from 1-4 PM Monday-Friday. Trethewey House Heritage Site is operated by Heritage Abbotsford Society, a registered non-profit. Our mission is to collect, record, preserve and share the stories of Abbotsford. We offer a range of programs and experiences including site tours, exhibits, historical Abbotsford walking tours, and more - all by donation. The Heritage Site consists of Trethewey House, Joey's Playhouse, the Upper Sumas Train Station, a Heritage Gallery, and the Sylvia Pincott Heritage Habitat Garden. Trethewey House was built in 1919-1920 by Joseph Ogle "J.O." Trethewey. As President of the Abbotsford Lumber Company, J.O. was responsible for leadership of the company during the company's boom years in the 1920s. The House is built in the local Craftsman style and was constructed using primarily local materials, making it distinct from other buildings of similar age within the City of Abbotsford.
