Hatai Bangkok is taking shape on the former Narai Hotel site in Silom, bringing together a redesigned Narai Hotel, Six Senses Bangkok and public spaces beneath lantern-inspired architecture. The Narai Hospitality Group development combines hotel accommodation with dining, retail and wellness, rather than treating the property as a standalone hotel replacement.
The project remains under construction. Its published opening schedules are not fully aligned, so a single opening date should not be read as a confirmed launch for both hotels.
Hatai Bangkok draws on Thai lantern design
Heatherwick Studio’s project overview describes stacked, rounded forms inspired by traditional Thai lanterns. The development is the studio’s first project in Thailand and is intended to reconnect the former hotel site with the surrounding streets.
The architect’s plans include 5,200 square metres of public space, with elevated walkways, planting and a restored canal. A market, event areas and a shrine form part of the proposed street-level programme. This public-realm figure should not be confused with the size of the hotel accommodation or the development site.
The developer’s construction timeline records the installation of the first façade panels on 5 May 2026, following demolition of the original Narai Hotel and Triple Two Silom buildings in 2022.
Two hotel brands, distinct offerings
Narai Hospitality Group’s August 2025 announcement describes a 245-room Narai Hotel joining The Unbound Collection by Hyatt. Its planned facilities include an all-day restaurant, rooftop dining, a lounge, a pool and flexible meeting and event spaces. The original Narai opened in 1968.
Six Senses’ announcement sets out approximately 100 rooms and suites, a spa and integrated wellness facilities. BAR Studio is responsible for the interiors, while Joyce Wang is designing a 700-square-metre suite and a signature restaurant. The development targets LEED Gold and WELL Gold certification; these are targets, not certifications already awarded.
Opening dates require distinction
Hatai’s timeline still lists the fourth quarter of 2027, and Heatherwick gives late 2027. However, the project’s current FAQ says the development is due to open in the first quarter of 2028. Narai’s announcement specifies early 2028, while Six Senses also identifies 2028 for its hotel.
For hotel operators and project partners, the distinction matters: completion of a mixed-use destination and the opening of its individual hotels are not necessarily the same milestone. Hatai also illustrates the redevelopment approach discussed in WINC Wire’s coverage of hotel repositioning in Thailand, combining an established location and heritage with new brands and public-facing uses.
