Abstract: An all wood foundation for mobile homes is provided upon which the mobile home can rest in a semipermanent installation. A plurality of composite wood beams of pressure treated lumber are mounted directly on a gravel support bed beneath the mobile home transversely of the length thereof with the longitudinal I-beams of the mobile home resting on the beams. A top plate of the beam is extended at either side to the edges of the mobile home for supporting a decorative wooden skirt which extends from the ground to the base of the mobile home.
