Siam@Siam Design Hotel — A Double-Decker Rooftop Pool on Floor 27 That Design Lovers Fall For
If you're tired of Pattaya hotels that all look the same and you want somewhere with real character, Siam@Siam Design Hotel Pattaya is the name design-minded travellers keep coming back to. It opened in 2012 on Pattaya Sai 2 Road right in North Pattaya, and the whole building runs an industrial-loft theme — exposed steel, brightly painted pipes, and odd, eye-catching art in every corner. What guests talk about most is the two-level double-decker pool — an all-ages level on the 24th floor and a rooftop pool on the 27th — and the Sky Bar Summer Club, billed as the highest rooftop in Pattaya, looking out over the whole bay — and Terminal 21 and Central are under a 5-minute walk away.
Siam@Siam Design Hotel Pattaya opened in 2012 as the younger sibling of the Bangkok property. The 25-floor tower holds 268 rooms and sits on Pattaya Sai 2 Road on the north side of town. The first thing you notice walking into the lobby is the full industrial-loft theme — high ceilings showing off boldly painted pipes and steel beams, a front desk wrapped in sheet metal, and art and objects on nearly every surface. Rooms split into Leisure Class and Biz Class at around 30–32 sqm, plus corner rooms with sea views. The in-room design plays with strong colour and uses artwork and furniture you won't find in a typical chain — guests who like things artsy love it, while anyone who prefers a clean, minimalist room may find it a little busy.
The real headline act is up top. The double-decker pool is a two-level pool the hotel says is the only one of its kind in Pattaya — a lower deck (BARBÙ) on the 24th floor that's open to all ages, and a rooftop pool on the 27th floor with an edge that looks straight out over Pattaya Bay, a big blue giant statue as a photo landmark, and rows of blue-and-white striped umbrellas along the deck. Right beside it is the Sky Bar Summer Club, a rooftop bar billed as the highest in the city, open to non-guests who want to come up for a drink and the sunset. One thing to know up front — the 27th-floor rooftop pool and bar are reserved for guests aged 16 and over, so families with young kids use the 24th-floor pool instead.
"Guests describe heading up to the 27th-floor rooftop pool in the evening, ordering a drink at the bar, and watching the sun set over Pattaya Bay — it didn't feel like any Pattaya hotel they'd stayed in before."
The dining carries the design theme through. Big Fish, the main restaurant, is fitted out industrial-style — exposed ceiling pipes, alternating red and blue chairs, painted lines across the floor — and serves both Thai and international dishes. The breakfast buffet opens around 6 am and draws regular praise for variety and quality. There's also On The Road, a café and bar downstairs for a more relaxed sit. The thing guests agree on most is that the staff are friendly and look after you well, especially the team running the rooftop.
Location is this hotel's trump card. It's on the north side on Pattaya Sai 2 Road, under a 5-minute walk to Terminal 21 Pattaya, Central Pattaya and Big C — shopping and food are genuinely easy. Pattaya Beach is about 600–700 metres away, an easy walk or a cheap songthaew ride. If you want to wander, shop and eat without relying on a car, this beats the hilltop hotels on Phra Tamnak that need a ride into town every time.
The Trip.com score sits at 9.1/10 from 1,174 reviews — location scores highest at 9.4, with cleanliness at 9.1. The honest gripes need saying plainly: reviews flag slow in-room Wi-Fi, especially on the middle floors, and road noise in some rooms since the building faces busy Pattaya Sai 2 Road. Some guests note the building and rooms are starting to show their age compared with when it first opened, and the morning checkout queue on weekends can run long. These are real limitations worth knowing before you book.
Pricing starts around ฿2,300/night for a Leisure room in low season, which is good value for a design hotel with a rooftop pool and a central location like this. In high season (November–February), long weekends, or Songkran, rates climb to roughly ฿3,200–4,000. If you want a clear sea view or a corner room, book ahead and request it at the time of booking — the better-view rooms sell out faster than the city-view ones.
The bottom line: Siam@Siam Design Hotel Pattaya works best for people who want a hotel with style, a walkable spot for shopping and eating, and a rooftop pool to photograph and take in the view — at a price that isn't steep. The trade-offs are rooms designed so boldly that some find them busy, Wi-Fi that isn't fast, and road noise in some rooms. If you're after a quiet private-beach retreat, this isn't it — but if you want a fun, characterful base right in town, it fits the brief.
