In-plant offices are modular structures that can be placed within large, open interior spaces such as warehouses, plants or factory floors. These portable office structures include more than just offices. You can also select from clean rooms, fully plumbed restrooms and more. Most include doors, lighting, and outlets. Items vary by whether they come assembled or unassembled, number of walls, dimensions, color, panel material, inclusions, standards conformance and other considerations.
