Event spaces feature refreshed interiors and upgraded technology.
Anantara Siam Bangkok Hotel has completed a US$50 million transformation of its landmark property on Rajadamri Road.
Since opening in 1983, the hotel designed by architect George Wimberley has gained recognition as a luxury address for international travellers, public figures and major events.
The redevelopment also covers all 335 guestrooms and suites, including Deluxe Rooms, Siam Suites, Anantara Suites and the Presidential Suite. Interiors have been redesigned with teak wood, handcrafted details, silk accents and a residential colour palette intended to reflect Thai design traditions in a contemporary setting. Bathrooms have also been upgraded with marble finishes, new vanities, improved lighting and modern fittings.
The hotel’s Grand Ballroom and supporting event spaces now feature updated technology and refreshed interiors, targeting international conferences, weddings, gala dinners and private celebrations.
A key part of the project is the conservation of the hotel’s cultural features, including the hand-painted mural above the lobby. The mural, created by Ajarn Paiboon Suwannakudt and depicting themes from Thai cosmology across 19 ceiling panels, has been restored as part of the renovation. Its preservation signals the hotel’s intention to modernise without diluting the visual identity that has defined the property for generations.
The transformation also introduces new accommodation concepts, including the Anantara Garden Pool Suites, set within tropical gardens and offering private pools and indoor-outdoor living spaces. Another addition is the Jim Thompson Suite, developed through a partnership with Jim Thompson and designed with teak floors, painted panelled walls, Thai-inspired artwork, an open-plan living and dining area, and a private library.
Food and beverage remains a central part of the hotel’s positioning. Its nine restaurants and bars include Spice Market, Biscotti, Shintaro, Madison Steak Avenue, Guilty Bangkok, Aqua Bar, Mocha & Muffins, The Lobby and The Garden Terrace, spanning Thai, Italian, Japanese, steakhouse, South American and casual dining concepts.
Wellness facilities have been expanded through a renewed Anantara Spa, the Siam Sport Club, a new Technogym-equipped fitness centre, a pilates studio and outdoor wellness areas for Muay Thai, rock climbing and functional training.
Torsten Richter, general manager of Anantara Siam Bangkok Hotel, said the transformation was intended to keep the hotel relevant to today’s travellers while preserving its heritage. “Iconic hotels must strike a balance, remaining relevant to the expectations of today’s traveller while protecting and preserving our heritage,” he said.
Richter added that the investment reflected confidence in Bangkok’s luxury hospitality sector and the hotel’s role in the city. “We believe there is still extraordinary growth potential in Bangkok’s luxury hospitality segment,” he said.
