The north-eastern block of the CCTV site is occupied by the two-story ring-shaped service building. It is a combination of the central energy center (for both CCTV and TVCC), the special broadcasting vehicle parking lot and the guards's dormitories. The accommodations for the guards are located in the ring floating above E8 road, establishing an optical closure from the ceremonial plaza towards the east of the site.
The lower portion of the ring in the south accommodates large broadcasting vehicles. The small vehicle garage, the energy center, and the fire control center are located within the box-shaped section to the north of E8 road.
