referring to fig3 the foundation posts 18 are suitably adjustably mounted to the support structure 12 to permit vertical adjustment for installation on uneven ground or to accommodate changes in the ground terrain the housing shell 13 includes four vertical corner columns 24 each corner column 24 extends vertically through and is secured within a corner of the support structure 12 each corner column 24 is suitably a hollow steel tube the corresponding foundation post 18 is slidably received within the lower end of the corner column 24 a clamp 26 is secured about the foundation post 18 immediately below the lower terminus of corner column 24 the corner column 24 bears on the thusly secured clamp 26 which transmits the load to the foundation post 18 the clamp 26 can be loosened and slid upwardly or downwardly to change the distance that the foundation post 18 projects downwardly below the corner column 24 thus each foundation post 18 may be independently adjusted upon placement of the housing unit 10 thereafter upon change in the terrain each foundation post may be adjusted by jacking up the corner of the support structure 12 undoing the clamp 26 sliding the foundation post 18 upwardly or downwardly as may be required and resecuring the clamp 26 the corresponding foundation pad 40 is secured to the lower portion of foundation post 18 by a plurality of reinforcement braces 22 foundation pad 40 is made of a suitable material such as concrete steel or timer pad foundation pad 40 is aptly suited to.
