A building foundation form apparatus and method uses transverse form supports (15) supported directly on the ground and carrying longitudinal form supports (21, 22) adjustably located on opposite sides of, and substantially parallel to, a foundation axis (17). A flexible sheet form element (25) has edge portions (57, 58) connected to the longitudinal form supports (21, 22) and a contact portion (60) located between the edge portions and supported on the ground and deformed into a general U-shape with overhanging bulges (39) to receive the flowable and settable foundation mixture. The longitudinal form supports (21, 22) are adjustable vertically to accommodate ground undulations to ensure correct footing width. The contact portion (60) has mesh openings to pass the foundation mixture therethrough to enhance adhesion to the ground. Also, the sheet form element has marginal portions (47, 48) extending upwardly from the contact portion to the bulges (39), the marginal portions (47, 48) having mesh openings which pass concrete mixture to fill voids beneath the overhanging bulges (39).
