Drugs are something that has been fought for for a long time and rehabilitation is one way to save victims from drug dependence. Therapy and rehabilitation methods using the Therapeutic Community approach are inseparable from the therapeutic communication carried out by addiction counselors which functions to create a comfortable atmosphere for residents who are drug addicts. This study aims to determine the community therapeutic variables at the rehabilitation center that are often used by patients: bedroom, common room and dining room at the drug rehabilitation center. This research method uses a comparative method by identifying the application of the therapeutic community principles in case studies. The buildings being compared include The Chiang Mai Cabin, the Lido BNN Drug Rehabilitation and Therapy Unit, the FAN Campus, West Java, and the Regional Mental Hospital, Bangka Belitung. The results showed that each room has a quality standard that must be met in order to increase the level of patient comfort at the Drug Rehabilitation Center. These results can help architects in designing drug rehabilitation centers with a therapeutic community approach.
