Abstract: Based on standard parameters of modular components and construction module, this study aims to establish the standardized system of modern light wood frame house in order to promote the change of industry from extensive to intensive: establishing 18 kinds of modular walls and 8 kinds of floor components to complete the database; establishing a design method which was determined by modular parameters, and come up with the basic module (1 M=610 mm). By theoretical calculation and model manufacture of a single-storey modern light wood frame house, the feasibility of this system is verified.
