There was no kitchen, stove or refrigerator. The communal living area provided about 9.1 square feet per occupant, just smaller than a yoga mat. Originally designed to hold about 200 people, it was designed with triple-decker bunk beds with single people separated by gender, and families between them. Walls were painted a pale, institutional green. Next to the bathrooms there was a very narrow “escape tunnel” that led out to an area near the street-side entrance. There were two bathrooms with three toilets, a urinal, two sinks and two decontamination showers. Other rooms were available to store food or provide simple medical care. There was a maintenance room with a diesel-powered electric generator, an air circulation system with heat and air conditioning, a well and pipes that connected to the city water and sewer systems. The hallway was designed with many right-angle turns to prevent gamma rays from reaching the interior.
The main entrance is a sliding, heavy metal grate that leads to an underground concrete hallway to the main part of the facility.
