The Abbotsford Lumber Company built this “arts and crafts” style bungalow in 1919 for B.C. lumber baron J.O. Trethewey. The house has been restored to c.1925 and furnished with donations from a number of local families and assistance from the Province of British Columbia through the British Columbia Arts Council and Direct Access Gaming.
Abbotsford’s most important early industries are represented in Trethewey House. It was built with the finest fir lumber produced at the mill on Mill Lake. The mill was operated by the Abbotsford Lumber Company, which was owned by J.O. and his brothers. The bricks used in the chimneys and fireplaces were made with clay mined on nearby Sumas Mountain and processed at Clayburn Village, B.C.’s first company town.
Trethewey House was designated as a heritage site in 1983, and is now operated by the MSA Museum Society. We encourage you to come view the house and enjoy our period gardens and spacious grounds.
The MSA Museum Office are located in the Carriage House, a reproduction of the original building used to house the Tretheweys’ automobiles and Joey’s pony and motorcycle. See an interpretation of Mill Lake and brief history of the company and its connections to the oldest extant Sikh Temple in Canada where Abbotsford Lumber donated building materials for its construction in 1911.
Joey Trethewey had the smallest family bedroom but compensation for this included the space for his pony and motorcycle in the Carriage House and his two room playhouse. Both the playhouse and the carriage house were rebuilt with the support of a BC Community Spirit Abbotsford 2000 project funded by the Province of BC and the MSA Museum Society. The playhouse serves as a pioneer classroom.
Upper Sumas BC Electric Railway Station was the original station on the BC Electric Railway Line. The Railway Line, which skirted the southern shore of Sumas Lake, was completed from New Westminster to Chilliwack in 1910. Learn the story of the Railway Line that had a dramatic effect on the profitability of dairy farming in the valley.
