The first generation of barracks were underground bunkers built with cements and reinforced concretes in the early 1970s; the second generation of barracks became blockhouses with sleeping quarters built on the ground, which are used as warehouses now; the third and fourth generations of barracks were modernized barracks, but they too have been turned into memorial halls and rooms of honor; the fifth generation is an innovatively designed three-storied building, in which spring beds has replaced the Chinese heatable brick beds and large boiler has replaced old-typed stove.

走进院内，一栋错落有致的三层小阁楼展现眼前，这已是哨所的第五代营房。五代营房忠实地记录着30多年的风雨历史。第一代营房是上个世纪70年代初用水泥钢筋浇铸的地下工事；第二代营房是地面上修筑的炮楼带宿舍的住房，现在已做了仓库；第三代、第四代营房是现代制式营房，但也变成了纪念馆、荣誉室；第五代营房是设计新颖的三层楼房，室内的钢丝床代替了小火炕，大锅炉代替了土炉子，暖气烧得热乎乎。
