Kanisius Jakarta College has a sports hall with various functions, namely for practicing sports, art activities, and academic activities (seminars, graduations, or religious activities). The sports hall was designed by Han Awal and built in 1990. Over time, minor changes were made to the room to overcome problems with air circulation, glare area, ease of maintenance, audio clarity, and so on. However, these design changes sometimes bring new problems. For example, installing curtains on windows that aim to reduce glare and heat in the morning makes the room dark and opening and closing the curtains takes a long time.
