Bangkok's luxury real estate market in 2026 continues to push new boundaries, with penthouses representing the highest level of residential living. These exclusive residences are designed for ultra-high-net-worth buyers who prioritize privacy, scale, and prime positioning within the city. Unlike standard condominium units, penthouses offer significantly larger layouts, private lift access, and unobstructed skyline views — often occupying entire top floors of a development.
Within Bangkok, Sukhumvit remains the most sought-after corridor for luxury living, particularly across Asoke, Phrom Phong, and Thonglor. Limited land supply combined with strong demand has created a highly competitive ultra-luxury segment, where penthouses are defined not only by size, but by branding, exclusivity, and location. The following represent some of the most expensive and prestigious penthouses available in Bangkok today.
1. InterContinental Residences Bangkok Asoke
The last available MALI Penthouse at InterContinental Residences Bangkok Asoke is a whole-floor simplex spanning 453 sq.m. within Bangkok's first InterContinental-branded residence. With only 88 units in the development and just a few residences per floor, privacy here is genuine rather than marketed. The fully-fitted interiors feature 3.1-meter ceiling heights, with generous living and dining areas that flow seamlessly throughout the floor plate. As a freehold offering in Sukhumvit's prime CBD — steps from both BTS Asoke and MRT Sukhumvit — this is among the rarest penthouse opportunities currently available in central Bangkok.
Positioned on the top floor of Still Sukhumvit 20, this penthouse offers 439 sq.m. of full-floor living — a level of privacy that is genuinely rare in central Sukhumvit. The layout is clearly thought through: a large open-plan living and dining area anchors the front of the residence, while the four-bedroom wing is set apart to ensure real separation between entertaining and private life.
Multiple bathrooms and dedicated service areas are woven into the plan, making this as practical as it is spacious. For buyers seeking a large-format home between Asoke and Phrom Phong, this penthouse is one of very few options at this scale.
The Trinity Triplex Penthouse at SCOPE Thonglor is among the most extraordinary residences in Bangkok — 756.5 sq.m. spread across three levels (floors 26–28) in the heart of Thonglor. Designed by Thomas Juul-Hansen, known for his luxury residential work in New York and London, the home reflects a refined and timeless approach to modern living.
The 4-bedroom, 5-bathroom layout includes a multipurpose room, powder room, and maid's quarters, with main living areas clearly separated from private spaces for both openness and privacy. A SIEMATIC kitchen with Gaggenau appliances sets the standard in the kitchen, while ceiling heights of up to 3.2 meters and full-height windows with advanced heat and noise-reducing glass bring light and calm throughout. Private lift access, a media lounge, and an outdoor terrace complete what is, by any measure, a one-of-a-kind home in Bangkok.
On the 24th floor of Mavista Phrom Phong, the Embassy 6 Penthouse offers 384 sq.m. of well-considered living space on Sukhumvit 39 — within easy reach of BTS Phrom Phong and The EM District.
The 4-bedroom layout opens into a large living and dining area connected to an island kitchen, with a separate preparation kitchen and service area keeping the main spaces uncluttered. Living and private zones are clearly defined throughout the floor plan. All four bedrooms are well-proportioned, with the master suite featuring a walk-in closet and a spacious en-suite bathroom.
Wide window frontage draws natural light deep into the main living areas — making this a rare large-format residence in one of Sukhumvit's most established and sought-after neighbourhoods.
The duplex penthouse at Mulberry Grove Sukhumvit offers 216.50 sq.m. across two levels, designed specifically around multi-generational family living. The layout separates main living and dining areas from the bedroom zones, striking a natural balance between space for entertaining and space for everyday life.
Multiple bedrooms with en-suite bathrooms, a closed kitchen, and flexible areas that work as a family lounge or home office give the residence real versatility. The signature multipurpose balcony creates an indoor-outdoor connection, with 3-meter ceilings, an ERV air system with air quality monitoring, and smart home controls reflect a standard of finish that goes beyond the visual. Located on Sukhumvit Road near BTS Ekkamai, the project sits within easy reach of international schools, lifestyle destinations, and key business areas.
6. The Residences at Mandarin Oriental, Bangkok
The last fully-fitted Heritage Penthouse Suite at The Residences at Mandarin Oriental Bangkok spans 709.42 sq.m. across floors 51 and 52, with open views over the Chao Phraya River. The duplex separates the residence into two distinct zones — living and entertaining on one level, bedrooms on the other — with the main living and dining space expansive, light-filled, and framed entirely by full-height windows and uninterrupted river views.
The unit includes 4 bedrooms, 2 multifunction rooms, and 2 maid's rooms, offering both scale and flexibility for long-term living. Delivered fully-fitted, it allows for complete interior customization while maintaining the premium standard expected of the Mandarin Oriental brand. For those seeking a large-scale riverfront home at one of Bangkok's most prestigious addresses, this is a genuinely rare opportunity.
This fully fitted duplex penthouse at The Residences 38 spans 426.50 sq.m. across the 35th and 36th floors at the entrance of Thonglor, with direct access to BTS Thong Lo. The interior offers generous living and dining areas, a closed kitchen, multiple bedrooms with en-suite bathrooms, and a separate maid's area — proportions that are rarely found this close to the heart of Sukhumvit.
The fully fitted delivery with high-quality materials and a clean, modern design means buyers can move in as-is or personalize the space entirely to their own taste. With international dining, lifestyle malls, and key business districts all within close reach, this penthouse works equally well as a long-term family home or a strong investment in one of Bangkok's most consistently performing corridors.
