A timber structural member includes: a first timber round having a first cooperating longitudinal surface, a second timber round having a second and a third cooperating longitudinal surfaces, and a third timber round having a fourth cooperating longitudinal surface. The first cooperating surface cooperates with the second cooperating surface, and the third cooperating surface cooperates with the fourth cooperating surface. The timber rounds are secured together to form a structurally integral unit in which the first cooperating surface is in contact with the second cooperating surface, and the third cooperating surface is in contact with the fourth cooperating surface, and the first, second and third timber rounds are substantially parallel to each other. The timber rounds are secured to each other by a plurality of spaced fasteners provided at acute and obtuse angles from a longitudinal axis of the structural member and extending through the timber rounds.
