Offsite construction technique presents substantially speedier construction processes whilst lowering construction wastes. The level of prefabricated for offsite construction projects depends largely on the amount of complexity and
the level of prefabricated components, which can be classified into two levels such as 2D penalized and 3D volumetric construction. However, there is often no specific method adoptable for determining the level of prefabrication
construction. This research aims to determine the level of prefabrication requirement for offsite construction and their significance. An online database collected for offsite construction projects was analysed with decision making models. The results revealed that the building volume, i.e., the building footprint and height were the most influential factors. Furthermore, three other factors related to timber material, low-income target user, and residential function of prefabricated projects were also identified as crucial in deciding the prefabrication level. The research concluded with certain guidance recommended for choosing the appropriate prefabrication level for building construction. For example, penalized construction generally had a higher level of implementation than volumetric construction in prefabrication.
