 Karmi was a full professor at the School of Architecture of Ariel University Center of Samaria.The massive Tel Aviv Central Bus Station, which Karmi designed along with the architects Tzvi Komet and Ya'el Rothschild, has been criticized over the years for being a difficult to navigate bloated structure which also destroyed the neighborhood it was built in, despite numerous advertising campaigns and improvements.In an interview, Haim Avigal, the CEO of the station from 2005, downplayed the navigation complaints, but said that "if I caught the architect who designed this building, I'd beat him up".
