Abstract: A structure is formed with a beam, floor and ceiling joists, studs, top and bottom plates, rafters and headers consisting of composite wooden members. The composite wood members include aligned pairs of elongated pieces, each piece including a narrow face, a wide face and a pair of radial faces. The faces extend longitudinally in relation to the piece. The pieces are bonded together at their narrow faces between the wide faces. The transverse cross-sectional geometry of each piece comprises a trapezoid with an apex side at the narrow face, a base side at the wide face and a pair of radial sides; each radial side being associated with a respective radial face. The members may be formed with pairs of tapered pieces oriented in opposite relation with respect to each other.
