A Bill Bensley and Krissada Sukosol Clapp design on the Chao Phraya River in Dusit, 39 suites and pool villas filled with the Sukosol family's Thai antique collection. The most architecturally distinctive hotel in Bangkok.
"Bill Bensley-designed boutique on the Chao Phraya, 39 suites and pool villas, Thai antiques throughout, and the most architecturally distinctive hotel in Bangkok. The most personal grand hotel in Asia."
The Siam opened in March 2012 on a three-acre riverside parcel in Dusit, the historic royal district of Bangkok upstream from the central tourist concentration and adjacent to the Chitralada Royal Villa and Wat Benchamabophit (the Marble Temple). The property was conceived and is owned by Krissada Sukosol Clapp, a member of the Sukosol family that has been in Bangkok hospitality since the 1970s, and designed in collaboration with American landscape architect and hotel designer Bill Bensley, the most decorated boutique-hotel architect working in Southeast Asia. The architectural register is Art Deco filtered through traditional Thai craft: black-and-white tiled floors, deep eaves, hand-painted murals referencing 1920s Thai theatre, and an extensive use of the Sukosol family's collection of Thai antiques throughout every public and guest space. The result is the most architecturally distinctive hotel in Bangkok and one of the most quoted Bensley designs in Asia.
There are 39 rooms and pool villas, every key in the property is a suite or larger. The standard Siam Suite runs to 80 square metres in the main building, with separate sitting and bedroom areas, hand-loomed Thai silk in mineral colours, original Bensley-sourced antiques, and full-height teak louvre doors opening to private balconies. The Pool Villas, 120 square metres each, are separate buildings within the gardens, each with a private 50-square-metre courtyard and a private plunge pool. Connie's Cottage is the property's most distinctive room: a 1920s teak Thai house relocated to the riverside (the original family home of an aunt of the owner) and restored as a single one-bedroom cottage with a private garden, the most authentic Thai vernacular hotel room in Bangkok. The interior register everywhere leans heavily on the Sukosol family's working antique collection, old Bangkok-port import-export ledgers, hand-painted opera fans, vintage Thai film posters, framed silk panels.
Chon Thai, the property's signature dining room, is set inside a 100-year-old teak Thai house relocated to the riverside and now serving classical central Thai cooking with the most extensive working antique-and-art collection of any hotel restaurant in Asia. Cafe Ce La Vi serves the all-day informal menu in the property's central courtyard. The Deco Bar & Bistro, set against a black-and-white-tiled lobby, runs a French-Thai cocktail and small-plate programme. The Authentic Thai Cooking Class, run on the property by Chef Pol, is among the most decorated hotel cooking classes in Asia. The Siam's working Muay Thai gym, built around an authentic full-size ring, runs daily Muay Thai training for guests with two former professional Thai champions on staff; the property is the only hotel in Asia with a full-time Muay Thai programme on premises.
The Opium Spa runs four treatment rooms in a separate riverside pavilion with a working herbal pharmacy and the brand's longstanding Ayurveda programme. The 50-metre rectangular pool sits at the centre of the property's gardens, framed by mature mango trees, lotus ponds, and the Bensley-designed art deco columns that anchor every long sightline. The hotel operates a private mahogany river boat for transfers, the Siam Saranporn, running on demand to the Sathorn pier and to the Mandarin Oriental in central Bangkok, a 25-minute journey. The Dusit position upstream from the central tourist concentration places the hotel in a quieter, more residential precinct of Bangkok, adjacent to Wat Benchamabophit and the Chitralada Royal Villa, a calmer rhythm than the Sathorn or Charoen Krung river properties.
For an Asian honeymoon at the boutique end, couples who prefer a smaller, more personal property over the brand-flagship grand hotels, The Siam is the most considered Bangkok booking. The Pool Villa for the standard programme; Connie's Cottage for milestone honeymoons (40 square metres of original Thai teak house with private garden, an unrepeatable booking). Honeymoon turn-down at The Siam runs to a hand-rolled chocolate selection from the property's pastry kitchen, an in-room jazz programme curated by the owner, and the morning Muay Thai session as an unusual couples activity.
For a solo Bangkok long weekend at the design-conscious end, a single creative or design-trade traveller spending three to five days on the city's architecture, antique markets, and design-trade, The Siam is the most considered booking. The Siam Suite as a standard booking; the Muay Thai programme; the cooking class with Chef Pol; the property's antique-and-art collection as the draw. The lobby and the bar are the most welcoming hotel public spaces in Bangkok to a single traveller.
For a Bangkok anniversary at the boutique end, couples who have already done the Mandarin Oriental and want something more personal for the second visit, The Siam is the answer. Connie's Cottage as a milestone-anniversary booking (the most distinctive hotel room in Bangkok); a private chef's-table dinner at Chon Thai for the night itself; a private river cruise on the Saranporn at sunset. The hotel handles every variant of the brief reflexively.
