What’s included in a standard portable site office?
Every unit includes a desk, office chair, filing cabinet, double sockets, lighting, and heating. Larger cabins also come with an office table and four chairs.
What is the purpose of a site office?
A site office, also known as a construction office or site cabin, is a temporary workspace located on or near a construction site. It acts as the central hub for project management, communication, and day-to-day administration. Typically equipped with desks, filing cabinets, and chairs, it allows site managers, engineers, and staff to coordinate work, store key documents and permits, and ensure compliance with regulations.

Our office container hire rates depend on the size of your unit and the duration of your hire. Give our friendly team a call today on 023 8033 2266 to discuss your needs and get a no obligation quote.
