Abstract: A free-standing fabricatable vertical wall or space divider is useful for partitioning buildings and/or office complexes. The wall is made up of a plurality of individualized and decorative flush panel units which are interchangeable and which are adapted to be readily inserted within a wall frame and locked into place without any visual showing of vertical supports used to lock the panels in place. The panels may be removed, redecorated and replaced as needed. Shelving or other appurtenances are attachable to the hidden vertical supports. The entire wall panel and/or divider is capable of replacement when it is desired to rearrange or enlarge or change a given floor space. Identical walls or dividers of the same basic construction are transversely connectable to each other.
