[1][2] The depot was designed by architects 61 and constructed by Hyundai Engineering & Construction Co. at a contract sum of S$350 million under contract C701.

It is the first in Singapore to be built with structural provisions for an industrial development to be situated on top, to minimise the waste of scarce land resources.

On 5 February 2021, LTA announced plans for the expansion of Sengkang LRT depot from the existing 3.5-hectare to 11.1-hectare.

The expanded depot will provide increased stabling capacity, a new maintenance workshop and two new reception tracks in anticipation for the procurement of 17 two-car trains to boost the Sengkang-Punggol LRT's (SPLRT) capacity.

Expansion works are slated to begin in end-2021, and scheduled to be completed by 2027.
