Mr. Chuan Chavanich, founded  Chavanich Company, Ltd. in 1944  and the shophouse he was renting in Talat Noi near Sieng Kong, was too small to accommodate the post-war trade. He needed more space to store large quantities of raw materials before exporting them to the United States. Having heard that Nai Lert didn’t want the land which the Japanese had occupied, he had expressed his own interest  in it, and when the time was right he  and his wife Manee bought this land along with the warehouses.

They also hired “Mr. Meng” to build the Chavanich Building as the company’s office. It is still located at house number 48, Captain Bush Lane, (Soi 30, Charoenkrung Road).
