What is a mobile office? A mobile office is just another term for a portable office or site office. Site offices are commonly found at most construction sites and are used as a communication base for organising workers and planning daily developments. A site office is constructed from a new or used shipping container and can be modified to suit the owners individual needs. Container King design and construct site offices based on there clients needs and fit them with optional site office accessories upon request. These mobile offices are then transported via a side loader to the clients location and setup for operation. Once the construction site has been developed the portable office is then transported to a new location where needed, quickly and easily. For more information on our site offices for sale, call Container King on 1300 266 824 and one of our site office consultants will answer and questions you may have.
