created with these types of panels and columns are such that it cannot create a flush wall surface because the surface at the columns will be protruding outwards from the surface of the panels as seen in fig1 however this problem is eliminated the panel 20 is shaped to have the same width as the column 30 and has a tongue at the end of the panel that is of a width and depth perfectly sized to fit the groove of the column 30 as seen in fig1 the tongue of the panel 20 would be trapezoidal shaped as opposed to rectangular shaped as shown in the embodiment in fig1 the columns 30 in any of the embodiments are secured in the ground in a number of ways such as by using reinforcement bars and a concrete footing as seen in fig2 a reinforcing structural bar 50 is secured in a concrete footing 70 firmly sunk in the ground the reinforcement bars 50 are sunk in the concrete while it is still wet and extend upwardly above the ground the bar 50 is essential in providing the structural reinforcement to the columns 30 all of the embodiments of the column 30 are formed with a central hollow 60 from the top to the bottom of the column the column 30 is placed over the reinforcement bar 50 which extends into the central hollow 60 a reinforcing filler such.
