Camp Echo consists of separate one-story buildings, each a cell divided into two rooms by mesh grates. This division allows lawyers to consult with detainees in the area of their cells. Military officials also use the facilities to interrogate detainees, shackling them to the floor.[1] The eight feet by ten feet (2.4 m by 3 m) concrete buildings have narrow, slotted translucent plastic in the doors but no real windows; they are air-conditioned and heated.
