A method for making a laminated cross lumber beam comprising the step of stacking elongated wood members and bonding adjacent longitudinal faces thereof along a bonding plane to form intermediary beams. The method further includes a step of selecting intermediary beams having a width greater than a predetermined value and cutting them lengthwise perpendicularly to the bonding planes such as to form panels. The panels and uncut intermediary beams then form sub-beam elements. The method also includes a step of bonding at least two sub-beam elements together side by side to form the laminated cross lumber beam. This method is simplified by the use of small wood members which eliminates the need to cut the intermediary beam to form the sub-beam element. It requires a minimum of steps, thus minimizing costs. The product of this method is a beam with optimized mechanical properties and visual appearance.
