William Scotsman has a long history that dates back to 1944. Williams Mobile Offices launched with an 8’ construction trailer that could be towed by a vehicle. In 1955, Williams Mobile Offices was incorporated, and ten years later, the company launched its first double wide mobile office. Since its launch, the WillScot company has expanded and gone public. In 2015, they launched their Flex panelized modular office solution.
