Featuring large skylights that naturally illuminate the upper concourse, Katong Park station has a depth of 26.8 metres (88 ft).

On 15 August 2014, the Land Transport Authority (LTA) announced that Katong Park station would be part of the proposed Thomson–East Coast line (TEL).

[5] The construction of the 3.6-kilometre (2.2-mile) bored tunnels required the use of 6.35-metre (20.8 ft) diameter Earth pressure balance (EPB) machines.

[6] The station was constructed in a narrow site along Meyer Road, surrounded by residential developments and the historical Katong Park.

[7][8] The contractors had to construct the tunnel launch shaft away from the station site to an empty area adjacent to Singapore Swimming Club.

[24] Drawing upon the park's history as a military fort and later a swimming spot,[24] the work seeks to explore themes of "memory, archaeology, time, and the body", connecting the past and present and blurring the boundaries between them.
