Shelving construction for customizing shelves used on interior walls of homes, offices or other buildings is described. Longitudinal members are first attached to a vertical interior wall for receiving shelf arms which are adjustably attached therealong. The longitudinal members are covered with a wood veneer and the shelf arms are then inserted into box-like wooden shelves which provide an all-wood appearance. The shelving construction can be easily modified by adding to the existing configuration. Each longitudinal member includes a series of grooves for receiving threaded plates which rotate for releasable engagement with the arms.
