Siam@Siam Design Hotel Bangkok — a bold industrial-art design hotel right in the heart of Siam
While most Bangkok hotels play it safe with muted, refined tones, Siam@Siam goes the other way — Siam@Siam Design Hotel Bangkok is a design hotel built from steel, recycled wood, stained glass and artwork, with a lobby that feels more like a gallery than a hotel. It sits on Rama 1 Road opposite the Suphachalasai Stadium, about a 5-minute walk from BTS National Stadium, and has a rooftop infinity pool and the Paradise Lost sky bar on the 25th floor with full views of the Bangkok skyline. Its 221 rooms start from approx. THB 3,200/night, with a score of 9.2 from 1,299 reviews on Trip.com.
Siam@Siam opened in 2007 and had a major renovation in 2018, and what people remember most is its bold, distinctive industrial-art design — exposed steel frames, recycled wood, stained glass, handmade lamps and artwork throughout the building. From the moment you step into the lobby, many guests say it feels like walking into an art gallery rather than a hotel. It isn't a look that suits everyone, but for anyone who loves creative, expressive interiors it's a selling point that's hard to find elsewhere.
Its 221 rooms range from the Leisure and Biz categories at around 28 sqm up to larger Studio rooms and suites. Most rooms are larger than you'd expect for central Siam, and the higher floors enjoy the city views reviewers praise. They're decorated in strong colours with bespoke design furniture. To be honest, though, the building has been in use for years — some rooms are starting to show wear and could use a maintenance refresh, which is the most common note in reviews. Ask to see the room at check-in and request a change if you're not happy.
"The design is genuinely cool and every corner is a photo op; the sky pool and the evening views are the highlight, and it's just a few minutes' walk to the BTS — but our room felt a bit dated and some staff were a little indifferent."
The part reviews mention most is the rooftop infinity pool and the Paradise Lost sky bar on the 25th floor. The pool isn't huge, but the evening atmosphere and the Bangkok skyline views make it the spot everyone wants to head up to for photos and a drink. Downstairs there are restaurants and a café, and the breakfast buffet is mostly praised for its variety — though a few reviews grumble about pre-cooked eggs or limited choices on certain days.
Where Siam@Siam wins is the location. It sits on Rama 1 Road opposite the Suphachalasai Stadium — about a 5-minute walk to BTS National Stadium, with easy onward links to Siam, Silom or Sukhumvit. MBK, Siam Discovery, the BACC art centre and the Jim Thompson House Museum are all within walking distance. It's an ideal base for anyone who wants to shop around Siam and rely on the BTS. The trade-off is that Rama 1 Road is busy with traffic, and street-facing rooms catch some of the noise.
Honestly, Siam@Siam is best for travellers who come for the design, the Siam location and the sky pool rather than those expecting a flawless brand-new hotel in every corner. If you love an artsy, photogenic stay in the heart of a shopping district right by the BTS, it delivers that at an attainable boutique price from around THB 3,200/night. But if you prioritise pristine new rooms, consistently warm service and quiet, the building's age and the occasionally uneven service may give you pause. It scores 9.2 from 1,299 reviews on Trip.com, which reflects that most who choose it for its character come away happy.
A tip from reading many reviews: ask for a higher floor for better city views and less street noise, and a recently refreshed room is far better value. Head up to the sky pool and bar around sunset for the best light. And since BTS National Stadium is a short walk away, relying on the train is much faster and cheaper than sitting in road traffic.
