The kanji 庫 is a phono-semantic compound (形声文字). It is composed of two parts: 广 (an abbreviated form of 广, meaning "shelter" or "building") and 㫿 (originally meaning "to choose" or "to pick out" then later related to "select" or "to gather"). The combination suggests a sheltered place (the 广 part) where goods are selected, gathered, or stored (the 㫿 part). Over time, the meaning narrowed to the function of a storage facility.
