This study is conducted in order to find a set of obstacles in implementing green construction concept in Indonesia. The study objective is achieved through an assessment of a case study of an apartment in Bandung, Indonesia. The assessment was performed using Assessment Green Construction model which was introduced by W. I. Ervianto in 2015. This assessment was conducted through the fulfilment of several indicators. The barrier is identified based on the reason behind the unimplemented indicator. The identified barrier from the highest percentage of occurrence to the lowest are no client demand, cost of investment, awareness, and site condition. The client demand issue could be overcome by the establishment of pertinent policy, official assessment system, and incentives. Contractor should aware about the business benefit of the investment. Further socialisation about several aspect of green construction is required to enhance the awareness of contractor. The site condition barrier should be addressed in the development of the Assessment Green Construction model.
