A storage structure is provided in which an outside surface panel can be attached and removed regardless of where the storage structure is installed. The storage structure has a plurality of columns, an outside surface panel configured to be located between two mutually adjacent columns to form a part of an outer wall, and an outward-side pressing member and an inward-side pressing member each of which can be removably attached to a column. The outside surface panel has a width which is less than a distance between the two mutually adjacent columns. The outward-side pressing member and the inward-side pressing member cooperate with each other to assist in holding the outside surface panel from both sides.
