Construction office trailers are mobile trailers (akin to mobile homes) that are outfitted with features to make them usable as an office. They give businesses the ability to have office spaces (with features like internet access) right at the job site. This provides a central location for communication and project management.

Construction trailers, most commonly referred to as mobile office trailers, job site trailers, or construction site trailers, are temporary mobile offices for construction sites. Construction companies use construction trailers to hold administrative staff, provide shelter from the heat and cold for employees, and more.
