Building is an important sector of today’s human life, where it meets the basic needs of modern humans for shelter and as a place for social activity and also to protect from the environmental threat. The importance of this sector is growing in line with the increasing number of population in need of new building development. Unfortunately, the high demand for new building development has become increasingly difficult due to the limited of vacant land available for development as a building development project. Consequently, refurbishment of existing buildings is one way to overcome this issue. However, recent studies have found that the success of the building refurbishment project is still not satisfactory. Previous studies have been conducted to determine the Critical Success Factors of building refurbishment projects, but they do not take into account important aspects of current development namely sustainability, technology and policy as well as Complexity Factors that are synonymous with building refurbishment projects compared to new building projects. Therefore, this study was conducted with the aim of establishing a multi-dimensional model of a building refurbishment project. To achieve this, Critical Success Factors are identified taking into account the sustainability, technology and policy aspects as well as Complexity Factors in influencing the building refurbishment project performance success. In this regard, the study was conducted through a quantitative method using the questionnaire form as a research medium to obtain feedback from the construction organization on the Critical Success Factors and the successful performance of the building refurbishment project. The questionnaire developed was distributed by employing self-administered method among managers to represent construction organizations operating in Kuala Lumpur and Selangor. As a result, 204 of the 240 questionnaires were fully completed. The analysis showed that all of the Critical Success Factors were categorized as critical to the success of the building refurbishment project and even had a strong relationship with the success of the building refurbishment project. The study also found that Complex Factors not only directly influence the success of the building refurbishment project but also have a significant impact on the relationship between the four Critical
Success Factors and the success of the building refurbishment project namely project management, environment, economic and policy. Overall, this study met the goals and objectives of the study. Finally, this study outlines strategies that can be implemented by construction organizations that carry out building refurbishment projects not only to
achieve better project success but also to impact the construction industry on leading a competitive industry and creating a better human environment
