His sash and door factory on Abbott Street, manufactured and sold windows and doors, custom furniture, and wooden fruit boxes for the expanding Okanagan fruit and vegetable industry. The business operated out of this location until 1948. Needing a reliable and accessible source of logs, Stanley Simpson bought land at Manhattan Beach along the lakeshore, in Kelowna's North End. In 1930, he began constructing a sawmill and box factory and three years later, added a veneer plant to the site. S.M. Simpson died in 1959. Horace B. Simpson, Stanley's son, managed S. M.
