Abstract: A building structure has a plurality of intermodal containers (ICs) attached together and substantially surrounding a central space. The ICs support roof elements, the roof elements together forming part of a roof for the building structure. Some of the ICs and the central space house functional equipment which is connected together at a deployment site to make a system capability. Some of the ICs walls together define an outer perimeter of the building structure while other IC walls facing into the central space have walls at least partially removed to allow access to the interior of the ICs from the central space.
