Mobile Offices sit up off the ground on tires and axels, requiring steps or ramps to access the building. They feature a hitch to easily hook up to and relocate on site if needed. Ground Level Offices (or GLOs) sit directly on the ground. Satellite offers several different size Mobile Offices with and without restrooms. GLOs come in two standard sizes and availability varies by location. Check with your local expert to see what is available in your area.
