Modular system allows many advantages in construction process and final production. Some of the lists are cost-effectiveness in terms of time consuming in site, labour, product materials and many more. The quality of modular system also can be monitored wisely as it develop in factory in mass production according to the design. Therefore there are posible to reduce risk in of non-functional components and create standardization of each component and interface. This paper proposes the implementation of modular system integrated with the traditional Malay house components potentianally the non-structural components such as wall, window and staircase. The traditional Malay house system is basically a modular system in terms of measurement, panel dismantle-reassemble method, expandable and moveable as well. The issues of modular using the traditional human measurement will be analysed using observation and site visit and analysis. Details of traditional Malay housing components will be analysed and the suitable components for modular system will be selected. The system that will be generated can be applied to the housing development in Malaysia and meantimes preserving the aesthetic elements of the traditional Malay house. The outcome of this paper will create a conceptual of modular housing system implemented of traditional housing components in building environment.
