The subject invention discloses an arbor comprising a frame having at least three wall supports attachable to each other, at least three legs, each leg attachable to the wall supports, a removable cover which overhangs the wall supports, and a plurality of side panels which may include mesh areas and zippered openings to allow access to the interior of the arbor. The side panels may be provided with anchoring strips to anchor the arbor to the ground. Each of the side panels may be removably attachable to an appropriate portion of the cover by means including a hook and loop strip appropriately disposed on adjacent edges of these components. Further, the arbor may also comprise roof supports where a peaked arbor is desired. The wall supports, roof supports, and legs may all be formed of respective members which can be selectively connectable to each other for length when the arbor is in use or detached from each other for convenience in storage and transportation. The wall supports may be connectable to each other and to respective roof supports and legs by wall joints which may provide a plurality of hollow tubes sized to selectively receive an end of the appropriate roof member, wall member, or leg. Similarly, a peak joint may be comprised of a backing and a plurality of tubes having hollowed ends adapted to receive the mating ends of the roof support.
