Therme Group, the Vienna-headquartered developer building a $1 billion “wellness attraction” in the Marina South Coastal area, has appointed former JTC Corporation CEO Tan Boon Khai as CEO of Therme Group Singapore.
Tan, who joined JTC in 2020 from the Singapore Land Authority, stepped down from the statutory board in charge of Singapore’s industrial progress in April 2025. He was previously senior vice president at CapitaLand and regional general manager for Singapore and Malaysia at hospitality operator The Ascott.
Therme Group announced in November 2025 that it had won a Singapore Tourism Board tender to develop “Asia’s first large-scale social well-being infrastructure project” on a 4ha waterfront site next to Marina Barrage and Gardens by the Bay.
The resort, known as Therme Singapore, is set to open in 2030. Therme Group expects its debut Asia property to attract around 2 million visitors a year when at full operational capacity, with about half of its guests coming from overseas.

Developed in partnership with Singaporean architecture firm DP Architects and Therme Group’s in-house architecture practice and design company, Therme Singapore will feature thermal pools, lush botanical landscapes, world-class art installations and cutting-edge health technology under one roof, according to the developer.
The facility will reportedly incorporate proprietary technology for “high-efficiency water recycling, sustainable energy solutions and advanced biophilic design”.

Therme Group Asia’s chairman is Mah Bow Tan, former Minister for National Development.
In a statement released Feb 2, Mah says Therme Group’s entry into Singapore aims to “make wellness accessible to all”. “Asia, particularly Singapore, presents great opportunities for Therme Singapore to showcase its wellness concepts and technology. Boon Khai’s leadership track record, deep expertise and strong stakeholder relationships will be invaluable in ensuring that Therme Singapore becomes an iconic wellness destination in Singapore, enhancing the vibrancy of the new Marina South Coastal area.”
Tan started his career as a Justice’s Law Clerk and Assistant Registrar at the Supreme Court of Singapore. He graduated with First Class Honours in Law from the University of Nottingham in the UK in 1995 and was called to the Bar with Lincoln’s Inn, UK. He was also an advocate and solicitor of the Supreme Court of Singapore.
Singapore is uniquely positioned to become a leading hub for urban wellbeing in Asia, says Tan. “I look forward to working closely with our partners and stakeholders to bring Therme Singapore’s vision to life — creating a world-class destination that enhances quality of life for both locals and visitors.”
