Seah and his wife Lorraine launched a hotel chain called Singapore Container Hotel, and in 2020, they opened their first hotel in an industrial enclave in central Singapore. They went on to open another hotel in Singapore's famous hell-themed park. In both hotels, the living space is made out of a single shipping container.

But Seah was still dreaming of something bigger: He wanted to build a luxury hotel out of four two-story shipping containers.

"I wanted to dispel the notion that recycling shipping containers is a cheap experience," Seah told Insider.

This month, Seah launched his third hotel location, called the Garden Pod, at the Gardens by the Bay, a 101-hectare park with views of the iconic Marina Bay Sands. The hotel took around two years to build.
