To increase housing parts, to provide a multi-surface desk usable from the other side face of front and rear surfaces as well by using vertically long housing parts passed through a large shelf plate on four corners and to easily stabilize a three-dimensional shape by using the large shelf plate and center upper and lower shelf plates or a connection vertical plate.

In order to pass the vertically long housing parts 4 and 6 and the respective vertically long housing parts facing them through the large shelf plate 2 and making them appear as the upper parts 4', 5', 6' and 7', notched horizontal lines 35, 36, 37 and 38 from vertical surfaces 9 and 17 on the inner side facing each other on the front surface and the rear surface are horizontally fitted to a horizontal notched line from the outer edge of the large shelf plate 2, erected and adhered and fixed by performing welding and embedding, etc. Thus, the housing parts are increased, this multi-surface desk usable from the other side face of the front and rear surfaces as well is attained and the three- dimensional shape is stabilized by using the large shelf plate 2 and the center upper and lower shelf plates 18 and 19 or the connection vertical plate 13.
