Ennismore will bring its 25hours Hotels brand to Thailand for the first time with a 345-room hotel in Bangkok's Siam Square. The 25hours Hotel Bangkok is scheduled to open in the first quarter of 2029 as part of a major new mixed-use development by Central Pattana. The signing, reported on 4 September 2026, plants one of hospitality's quirkiest lifestyle brands in the middle of the city's youth-culture district.
Siam Square is deliberate positioning. The open-air retail zone next to Chulalongkorn University and Siam Station runs on independent boutiques, pop-ups and creative studios rather than luxury malls. A story-led design hotel fits that energy far better than another glass tower on Sukhumvit.
25hours Hotel Bangkok: location and opening date
The hotel anchors part of Central Central, Central Pattana's new mixed-use project combining retail, workplaces, hospitality and public spaces. The wider development opens in phases from 2027, with the hotel following in early 2029.
Location fundamentals are strong. Siam Station's BTS interchange puts both airports and the riverside within easy reach, and the district draws Bangkok's student and creative crowds daily. For visitors, that means street-level energy rather than a hermetic resort bubble. Travellers mapping out the city should pair this news with what is new in Bangkok this year and the context that Bangkok remains among Asia's most-booked cities.
What makes 25hours different?
25hours Hotels, part of the Ennismore collective, builds each property around a story rather than a template. Bangkok's edition will draw on the city's creative character and urban identity, with interiors referencing Siam Square's independent retail scene and the district's Art Deco-influenced architectural heritage.
"Bangkok is a city of contrasts, creativity and constant motion, exactly the kind of place where 25hours thrives," said Sylvain Pasdeloup, chief operations officer at Ennismore. "With this project, we're creating more than a hotel; we're shaping a living, breathing space where culture, community and creativity come together."
Phoom Chirathivat, head of hotels and alternative investments at Central Pattana, said the partnership brings the brand to an established part of Bangkok known for bringing generations together. The project extends Ennismore's continued expansion across Asia-Pacific and the Middle East.
Bangkok's lifestyle hotel race heats up
The 25hours signing lands amid a wave of Bangkok hotel debuts as owners bet on the city's post-recovery demand. It follows hot on the heels of Fairmont's own Thailand debut on Sukhumvit, and the two tell a story about segmentation: Fairmont chasing luxury business travel, 25hours chasing creative-class leisure and weekenders.
A 2029 opening looks distant, but hotel development cycles run long in Bangkok. Signings announced now secure pipeline for the decade's second half, when analysts expect the city's room supply to tighten if arrival growth continues at its current pace.
