With the construction of the Chatswood to Epping line, it was decided to redevelop the station to accommodate Chatswood's new role as a junction station. The original station, as well as the attached bus interchange and shopping centre were demolished in 2005 and a temporary station was opened where the former platform 3 was located. A new western island platform opened in place of the original island platform on 16 October 2006. The eastern island platform opened in 2008. The signal cabin that was located at the northern end of the station building, was saved and has been preserved as part of the bus interchange.
