Glulam is used for the construction of multi-use facilities such as churches, school buildings, and libraries, and the Cathedral of Christ the Light in Oakland, California, is one of the examples of a way to enhance the ecological and aesthetic effect. It was built as the replacement of the Cathedral of Saint Francis de Sales, which became unusable because of the Loma Prieta earthquake in 1989. The , vesica piscis-shaped building formed the frame with a glued-laminated timber beam and steel-rod skeleton covered with a glass skin. Considering the conventional way of construction with steel or reinforced concrete moment-frame, this glulam-and-steel combination case is regarded as an advanced way to realize the economy and aesthetic in the construction.
