[1] Developed by City Developments Limited, Lot One was opened in August 1996 as the first major shopping mall in Choa Chu Kang.

Like a typical suburban mall that time, it featured a Shaw Theatres cinema, an NTUC FairPrice supermarket, a Seiyu (now BHG) department store, the Choa Chu Kang Public Library, a Cathay bowling alley, a video games arcade, a Food Junction food court and slightly over 100 specialty shops.

A roof garden, incorporating a wet and dry playground, was added during the final phase of the renovation.

In 2019, the cinema and library were closed for extensive renovation works, in which the cinema had its number of screens doubled to meet the needs of moviegoers in the area, while the library had its space expanded to include more content.

In its place, Cotton On and Uniqlo opened in November 2023.
