In 2017, a new concourse and ticket office was opened in St Erth, replacing the old ticket office which was smaller. The new building now includes toilet facilities and a waiting lounge, including a medium-sized ticket office with two windows. This process also included upgraded step-free access to the concourse and to platforms 2 & 3. A new entrance to platforms 2 & 3 near to the station cafe was also built, next to an also new private building for staff only. An improved transport interchange is under construction in 2018.
