Door (户) + axe (斤) = the place where work gets done
A door (户) plus an axe (斤) originally evoked a place where woodcutting happens — hence a specific location or premises. Over time 所 extended to mark 'that which' and introduce relative or passive constructions, while retaining its core sense of a bounded place or institution.
