A protective housing is formed of a set wall panels, a base panel, and a lid panel that interlock to form the housing, but may also be taken apart and stored as a stack of two-dimensional panels when not in use. The various panels interlock via configurations internal to the housing itself, so that once an external lock is placed to secure the access door to the front wall panel, it is completely self-contained and impossible to dismantle or otherwise take apart the individual components of the housing from the outside. The rear wall and/or a side wall are formed to include exhaust locations for an included generator, thus requiring no additional ventilation system to be separately constructed and included. The walls may be formed of steel, high density plastic, fiberglass, or other suitable rugged material appropriate for use in structures exposed to the environment.
