Rochor MRT Station is an underground station along the Downtown Line (DTL) Stage 2, located at the boundaries of the Little India and Bencoolen planning subzones. It is built underneath Sungei Road and Rochor Canal Road, serving parts of the vibrant Bugis, Rochor and Little India district.

The station is located in the vicinity of shopping centres, office and retail mixed-use developments, preserved shophouses and LASALLE College of the Arts. Construction of the station involved significant engineering challenges to divert the Rochor Canal and building the station underneath the future North-South Expressway and Rochor Canal.

iDAS double bank rainproof ventilation louvre system is not only able to satisfy high rainproof performance requirements but also relatively high ventilation requirements; thereby effectively resolving the conflicts between ventilation and rain protection.
