The kanji 局 is a phono-semantic compound (形声文字, けいせいもじ). The left side is a radical representing "building" or "enclosure" (尸, しかばね). The right side is a phonetic component that provides the sound (口, くち - mouth). The original meaning seems to relate to a space or area within an enclosed structure. Over time, it came to be used for administrative offices and other specialized locations.
