Sustainability is often limited by the natural laws that govern the natural system. The methodology used for this research is qualitative. This study adopted the qualitative method. The study initially conducted ten interviews and by the tenth interview, the researcher started to observe saturation in the themes and information. However, the researcher then continued to conduct five more interviews to have sufficient qualitative data and ensure comprehensive information. It was also revealed that the educated stakeholder also contributes greatly to promoting the implementation of sustainability in the planning phase. However, in the design phase, the factor which was identified that contribute greatly toward promoting sustainability implementation in the construction industry includes budget, schematics, action plan, community participation, technological development, political cohesion and alternative plans.
