PB hotel design editorial

Facing Lumpini Park from the northern edge of Silom, where Bangkok's financial district softens into one of the city's few patches of genuine green, a 30-storey tower clad in dark glass and charcoal metalwork announced itself in 2012 as something deliberately different from the grand-dame hotels further along the river. SO/ Bangkok was conceived as the Sofitel SO brand's Asia flagship, with five Thai designers each interpreting one of the classical elements — earth, water, wind, fire, metal — across dedicated room categories, producing interiors that shift character from floor to floor rather than maintaining the uniform palette most tower hotels default to. The rooms visible in the images bear out that ambition in tactile terms: herringbone-laid hardwood floors, vertical timber slat screens dividing sleeping from working zones, slatted wood ceiling panels, and dark-stained millwork running beneath floor-to-ceiling glazing that frames the park canopy and city skyline beyond. The restaurant carries an entirely different register — lacquered black surfaces, bold ukiyo-e-inspired murals, chains suspending white dome pendants above a sushi counter in marble, the whole space channelling an exuberant Japanese izakaya energy rather than hotel-dining restraint. Above it all, a mosaic-tiled infinity pool on the upper levels delivers what the tower's position always promised: Lumpini's treetops dissolving into the mid-distance, with the Silom and Sathorn skyline stacked behind.

"We joined chocolate making class. What a good experience and fun class. Chef Da is lovely and told lots of information about chocolate. The taste of chocolate is so good."

"As a regular returning guest for the past 15 years, I always look forward to staying here. This visit was good overall, but it didn’t quite live up to the exceptional experiences I’ve had in the past. The Club Level suite was absolutely stunning. It was spacious, beautifully designed, and equipped with plenty of thoughtful features and luxury touches. The room itself was definitely the highlight of our stay. The service was good and the staff were friendly, but it didn’t reach the outstanding level of hospitality that Thailand is so well known for. There were a few moments where the attention to detail and proactive service were missing. Unfortunately, the booking process was bumpy once again. As a loyal guest who has been returning for 15 years, I had hoped for a smoother experience and a little more recognition of my long-standing loyalty. That extra personal touch that makes returning guests feel truly valued was missing this time. Overall, we still enjoyed our stay thanks to the beautiful accommodation, but I hope the management can improve the guest experience for loyal returning visitors. With a few refinements, this hotel could once again deliver the exceptional standard it is capable of."

"We had a wonderful time at the chocolate-making workshop! The class was fun, well organized, and engaging for children. The instructor was patient, friendly, and explained every step clearly. It was a wonderful hands-on experience, and the chocolates turned out to be delicious. Highly recommended for families looking for a fun and creative activity!"

"I had high hopes for this hotel but it seriously fails on providing value for money or the level of service you expect from staff of a 5 star hotel. The check in process was incredibly slow and it felt like there was a lot of staff being busy without actually helping. Staff were fairly unresponsive and follow ups were usually required. The rooms were nice and well appointed although were lacking features you expect of a hotel like this. Was advertised with free soft drinks in the minibar but these were not soft drinks at all. While it may seem like relatively small grievances, these are things you expect of hotels which market themselves in this way."

"The hotel is simply wonderful! I had a great experience, the room was big and spacious. Everything I needed was in the room, nothing was missing. The lounge was also excellent! And the staff is amazing and courteous, always happy to help. I really felt like they remembered me and what I like! I will definitely return to this hotel! Highly recommend!!❤️"
