Traditional Chinese medicine group Eu Yan Sang International (EYSI) is under one roof for the first time since it started 134 years ago.

It moved all its offices and operations to its new headquarters in Tai Seng Drive a month ago and officially opened the facility today. The main office was originally at South Beach Road.

Home is now a 78,000 sq ft building with 40 years left on its lease tenure. It was acquired from an investment firm for about $12 million two years ago, said EYSI group chief executive Richard Eu.

He said the company can now group its functions together to improve efficiency.

"The move will bring all of our business operations together under one roof, giving us the space and convenience to facilitate further development as we continue to grow regionally," he said.

He told The Straits Times that it made business sense for the firm to acquire its own warehouse in view of escalating rents.

He noted the facility's open concept and bright colour scheme - keen to avoid a rigid corporate culture, he modelled the premises after those of firms known for their creativity such as Google.

The office even has booths where staff can enjoy traditional Chinese massages during breaks.

"Your office is actually your second home, you spend more time there than at home, so you have to try to make it as comfortable as possible," Mr Eu said.
