Laminated interlocking stackable wall units are assembled using a large proportion of wood species unsuitable for use in the construction industry. The interlocking stackable wall units are used in combination with a laminated roof beam, and a roof panel to construct an earthquake-resistant buildings. Each building is tied together by composite steel bands that lend the structure flexibility and excellent resistance to wracking forces induced by natural phenomena, such as earthquakes and windstorms. The buildings are rapidly assembled with a minimum of labour, and are inexpensive to construct. The advantage is a high quality building constructed at reasonable cost.
