Abundant still in Europe and the primary single-family home building material in the United States, timber is rarely used in multi-story construction in China. Though timber can be a fire-rated material, light wood-frame construction raises issues of combustion that are more difficult to manage. In addition, there is greater risk in durability due to the deteriorating effects of water. Therefore, timber will most likely not be a primary material in the superstructure of buildings in China.

However, the use of wood in the form of engineered wood products has good potential, especially with respect to the growing modular housing industry (Brown 2001). Engineered wood uses timbermill waste products such as shavings, sawdust, and chips within a binding matrix. In addition, used formwork can be reclaimed and pulverized and used in another generation of composite products. Products include oriented strand board, particleboard, laminated wood, and other composite materials of good dimensional stability and durability (Figures 9 and 10). Plywood is a readily available product in China. However, formaldehyde is still widely used in China. A proven cause of unhealthy indoor air quality, formaldehyde should be carefully avoided in the making of engineered wood products.
