It is built on the Tuen Mun Nullah immediately east of Siu Hong Court.

The topping-out was marked on 26 February 2002 by KCR chairman Michael Tien and transport legislator Miriam Lau.

To support the station, 352 columns were built in the river bed, impacting the water flow.

As a result, the river was widened by about 17 metres along the length of the station to maintain its drainage capacity.

Hence, Siu Hong was included in the project and is now an intermediate station on the Tuen Ma line.
