The Diplomat Penthouse for sale
The Diplomat Penthouse
Sukhumvit, Bangkok, TH
Occupying an entire floor above Sukhumvit, this four-bedroom penthouse pairs gallery-like interiors furnished by leading international maisons with a glazed pavilion and panoramic city views.
The Diplomat is a 31-storey development of Palladian-inspired architecture, with 391 one- to four-bedroom apartments. The penthouse takes the whole 30th floor, and expansive glass windows fill the interior with natural light.
Interiors follow a monochrome palette of black and white, with refined finishes and furnishings by Liaigre, B&B Italia, and Minotti. The owner’s brief to the designer asked for a modern, slightly avant-garde home that could hold a family and entertain friends. Pieces from Zaha Hadid, Ligne Roset, and Alexander Lamont complete the rooms, which are arranged like a gallery yet remain warm.
The dining area spills onto the balcony, where the skyline runs through 180 degrees. A glass pavilion lets the owner use the terrace in any weather, and the east-facing terraces avoid the harsh Thai afternoon sun and stay usable through the afternoon.

“The Diplomat stood out immediately for its timeless elegance and prime location in the heart of Sukhumvit. As a penthouse, it offered not only exceptional privacy and exclusivity but also panoramic views over one of Bangkok’s most dynamic districts. The refined architecture, low-density design, and proximity to the BTS Phrom Phong station and top-tier amenities made it an easy decision.
“The brief I gave to my designer was that this penthouse has to be modern, and a bit avant-garde. It has to not just accommodate everyone in my family but also help us entertain our friends and create a lasting impression.
“It is built to be a permanent home in the city with room to spare, where we can live exceptionally well and entertain our friends, and most importantly it has to embody an avant-garde modern style that allows us to enjoy good art and good design, every day.
“The penthouse is also furnished with a handpicked selection of pieces from world-renowned brands—Minotti, Christian Liaigre, B&B Italia, Zaha Hadid’s iconic sculptural furniture, Ligne Roset, and Alexander Lamont. Each piece was chosen not just for aesthetics, but for how it contributes to the atmosphere. The interiors feel curated like a gallery, yet warm and inviting—creating a seamless dialogue between design, light, and sky.
“The ‘Glass’ pavilion allows me to enjoy the view of the city with the terrace regardless of the weather. They’re also east-facing, which is perfect since the sun in Thailand is especially unforgiving in the afternoon. What that means is that I’m able to enjoy the outdoor terrace from much earlier in the afternoon than westward-facing terraces, and it’s something that is totally underrated here.
“It’s close to the city’s best dining, shopping, and cultural attractions, including EmQuartier and Benjasiri Park, but still maintains a sense of calm and community. Everything is walkable.”
Phrom Phong, centred on Soi Sukhumvit 39 and Soi 24, is the part of Sukhumvit organised around the EmQuartier, EmSphere and Emporium malls, Benchasiri Park, and the BTS station that serves them. The owner describes a district that keeps a sense of calm and community despite its position, where everything is walkable.
Daily errands, dining, and school runs fall within the neighbourhood: a hospital with a children’s campus on Soi 49, an international school on Soi 15 near Asok, and the park beside the malls.
—EmQuartier, the shopping and dining mall with six storeys of dining terraces and an open-air garden on the fifth floor
—Emporium and EmSphere, the neighbouring malls, linked with EmQuartier to Phrom Phong station by skybridge
—Benchasiri Park, 4.7 hectares around an ornamental lake, with a jogging area, sculptures and a playground
—Samitivej Sukhumvit Hospital on Soi 49, with Samitivej Children’s Hospital on the same site
—New International School of Thailand on Soi 15 near Asok BTS, an IB school for ages three to 18
