A pinned foundation system with resiliency under certain loading conditions and requiring minimum excavation, having a cast footing in combination with a plurality of sleeves through which piles may be driven into the soil to create the necessary bearing, uplift and lateral forces to support a structure. The sleeves are retained in fixed position relative to the footing, at predetermined angles corresponding to the specific structure loading characteristics desired for the ensuing foundation.
