The Kamppi metro station was built with a secondary platform located perpendicularly under the one in use, reserved for a future metro extension. The hall was dug in the 1970s in connection to the construction of the current station as it was cheaper this way. The bottom of the hall is about thirty metres below sea level, about fifteen metres below the current platform hall. This secondary platform hall is not equipped in any way. The hall is designed to allow metro trains to travel perpendicular to the trains on the current metro level. The hall can currently be accessed by a spiralling staircase leading down from an exhibition showcase in the centre of the current station platform. If the second platform hall is ever taken into use, a set of escalators will be installed at the same spot. The second platform hall has effective air conditioning intended to remove the radon gas leaking to the space from the rock walls. ==Art==
