Minor Hotels invests US$50 million to renovate Anantara Siam Bangkok, the original Grand Dame of Thai luxury hospitality. This evolution places cultural storytelling, sensory rituals, and guest immersion at the very heart of the experience.
“This transformation marks a defining moment in Anantara Siam’s journey,” said Torsten Richter, General Manager, Anantara Siam Bangkok Hotel.
“For nearly five decades, this hotel has been a symbol of classic Thai luxury and cultural refinement. Iconic hotels must strike a balance.
That remaining relevant to the expectations of today’s traveller while protecting and preserving their heritage.
Our discerning clientele, who value first-class quality and immersive experiences, expect nothing less than the extraordinary, and it is our responsibility to continually exceed those expectations.” He said.
Minor Hotels invests US$50 million
He added that “We are making a historically significant investment in this transformation, and the magnitude of the USD $50 million commitment reflects the scale and ambition of our vision.
We believe there is still extraordinary growth potential in Bangkok’s luxury hospitality segment.
Anantara Siam has long played a vital role in anchoring the heart of the capital — not just for international visitors, but for our local community as well.
We look forward to continuing that legacy, and to delivering a new era of unforgettable experiences that only Anantara Siam can provide.”
This reimagining of Anantara Siam forms part of Minor Hotels’ broader strategy to redefine Thai luxury hospitality across its Anantara Hotels & Resort portfolio in the Kingdom.
On the island of Koh Samui, Anantara Lawana has completed a full-scale transformation,
and Anantara Bophut has unveiled newly refurbished guest rooms and introduced enhanced wellness and family offerings.
Anantara Hua Hin is entering the final phase of a comprehensive multi-year enhancement,
while Anantara Mai Khao in Phuket is launching new beachfront lifestyle concepts.
Together, these developments reflect a nationwide evolution of Thai hospitality grounded in authenticity, creativity, and a sense of place.
“Transformed. Timeless. Thai.,”
He added that designed to reframe what luxury means for today’s traveller, the reimagined Anantara Siam will deepen its identity.
As a living cultural landmark—one where every stay becomes a journey through Thailand’s rich traditions and timeless elegance.
Now entering its fifth decade, Anantara Siam has long stood as a cultural cornerstone in the heart of Ratchadamri, Bangkok’s most prestigious neighbourhood.
Originally opened in 1983 and designed by acclaimed architect George Wimberley.
The hotel has earned its reputation as one of Asia’s most treasured addresses—a place where hand-painted murals, tranquil garden courtyards.
As storied hospitality have defined the art of Thai luxury. Guided by the brand philosophy of “Transformed. Timeless. Thai.,”.
This new era will honour the essence of the property while introducing inspired contemporary design,
elevated experiences, and a renewed sense of discovery.
