Trinity Art Space at 115A Commonwealth Drive is here. However, Mapbox/OpenStreetMap shows Trinity Art Space to be somewhere else in Singapore.

Free Community Church (and Pelangi Pride Centre within) supposedly around here?

This road is one way only. So to go to Lobby 23-28 you need to go the other way around.
