Anantara Siam Bangkok will undergo works across two phased stages.
Anantara Siam Bangkok is embarking on a US$50 million renovation programme across the hotel, which will include several upgrades to its meeting spaces.
The hotel, which opened in 1983, will undergo works across two phased stages to ensure uninterrupted guest stays. Phase one, running through November 2025, will see the reimagining of the Montathip and Kannika Court guest rooms and suites, Garden Terrace Rooms, Kasara Lounge, swimming pool and terrace, fitness centre and selected ground-floor meeting spaces.
Phase two, running from May to September 2026, will focus on the Garden Pool Villas, Parichart Court guest rooms, the Spice Market restaurant, the grand lobby, the ballroom, and all remaining meeting and event spaces. All dining venues and upper-level function spaces will remain fully operational throughout both phases.
With regard to the meeting spaces, the Ballroom’s pre-function area will be significantly expanded by transforming a portion of the existing outdoor space into an enclosed indoor venue, offering more flexibility for guest arrivals, with space for welcome cocktails or breakout sessions.
Technology will also be enhanced across meeting spaces, with digital screens added to the Monthathip 1–3 meeting spaces, as well as the Ballroom. The Boardroom will be completely refreshed with new designer furnishings, a larger TV, and a smart working table equipped with integrated charging stations. All function rooms will also receive upgraded sound systems to deliver exceptional audio quality. The hotel is also introducing a modern co-working and flexible workspace concept on the second floor, available for short-term rental or creative collaboration.
Anantara Siam Bangkok is also introducing a number of cultural immersion activities, inviting guests to connect meaningfully with local traditions, from morning alms-giving rituals to guided cultural storytelling and Thai botanical cocktail hours.
Torsten Richter, general manager at Anantara Siam Bangkok Hotel said: “This transformation marks a defining moment in Anantara Siam’s journey. For nearly five decades, this hotel has been a symbol of classic Thai luxury and cultural refinement. Iconic hotels must strike a balance – remaining relevant to the expectations of today’s traveller while protecting and preserving their heritage.’
