12 Bb Duplex Penthouse Von Barbara Barry | Möbliert | 453 M², 6,5 M Decken

Property Highlights:

Residence 12BB holds half of the twelfth floor of Windshell Naradhiwas: 453.28 sqm (4,879 sq ft), freehold, reached through a private lift lobby that serves nobody else — one of only thirty-six homes across the entire building, two to a floor. At the asking price of THB [hidden information], one million US dollars buys approximately 77 sqm here — against 62 in Dubai, 37 in Tokyo, 34 in New York, 33 in London, 28 in Singapore, 23 in Hong Kong, and 16 in Monaco (Knight Frank, PIRI 2026). Few residential markets left in Asia offer this ratio of space to price at the freehold, prime-address level.

It is the more compact of the tower’s two principal layouts and, for many buyers, the more finely proportioned: ample for a double-height Great room featuring 6.5-meter high ceilings, a full family plan, and staff quarters, without the obligation of an entire floor.

Architectural Volume & Communal Elegance:

What this residence shares with every home here is volume, and volume is what makes the building difficult to replicate. Conceived by a visionary developer, Windshell was constructed with seven metres — twenty-three feet — between floors, roughly twice the standard dimension of a luxury tower in Asia. That is why the living and dining room rises through two storeys, and why the floor-to-ceiling French windows run the full height of the room.

Terraces are carved into both facades and planted, so the home looks out onto a garden on two sides. Architect Kevin Mark Low described the result as Thailand’s first tropical stacking home, perfectly complemented by the building’s exquisite communal areas shaped by esteemed design houses like Studio Daminato and Pernille Lind Studio.

The CHANINTR Residence: A Turnkey Masterpiece by Barbara Barry:

While units at Windshell are deliberately offered as bare shells to allow custom architectural build-outs, Residence 12BB presents a remarkably rare turnkey opportunity: it is a fully realized CHANINTR Residence at Windshell. The interior is masterfully designed by Barbara Barry, an AD100 designer globally celebrated for creating iconic luxury spaces. Embracing her guiding principles of Simplicity, Harmony, and Balance, the residence exudes a level of comfort and refinement par excellence.

The home is delivered comprehensively finished and furnished, featuring world-class loose furniture and fittings curated from Barbara Barry for Baker and McGuire, alongside select pieces from Minotti and Liaigre. Bespoke millwork includes custom cabinetry and wall paneling designed by Barbara Barry in her signature grey-toned oak. The uncompromising materials are evident through the solid grand oak wood wide plank flooring by Dinesen of Denmark on the upper floor, while imported golden beige limestone flooring flows through the lower ground level. Culinary excellence is achieved with a European open feature kitchen by bulthaup Germany, equipped with Sub-Zero and Wolf appliances, complemented by a separate custom Thai kitchen.

The home offers luxurious sanctuaries, including a master bedroom suite featuring a private outdoor terrace, a double-sized shower, a freestanding bathtub, and high-quality fittings by Waterworks. Additionally, a prominent West-facing outdoor plunge pool and sundeck provide a private oasis for relaxation.

Advanced Wellness & Smart Home Technology:

Designed for the ultimate modern lifestyle, this residence integrates state-of-the-art health and environmental controls—a crucial luxury in today’s urban markets. A Daikin VRV system integrated with Respilon nano-filters removes PM2.5, smog, and pollen, monitored constantly by IQ AirVisual.

Holistic wellness is further ensured with a water purification system servicing the entire residence, and a custom walk-in wardrobe featuring LEMA’s patented Air Cleaning System. Seamless smart integration is provided via Apple Home Kit, voice control, and Lutron lighting systems, while SONOS audio visual systems deliver an immersive acoustic experience throughout the home.

The Neighbourhood:

Sathorn is where Bangkok keeps its institutions: the headquarters of the country’s banks, a concentration of embassies and diplomatic residences, and the city’s longest-established international community. In the geography of the capital, it is the quiet quarter behind the financial centre rather than the shopping district in front of it. Windshell stands on the southern stretch of Naradhiwas Rajanagarindra Road near Chan Road — minutes from the Sathorn-Silom central business district, and off its traffic.

Lumphini Park, the Michelin-starred restaurants of Silom and Sathorn, and the Chao Phraya riverfront hotels — Mandarin Oriental, The Peninsula, Capella — are all close at hand. Sold freehold and available within the building’s 49% foreign ownership quota — perpetual, outright title registered at the Land Department in the purchaser’s own name. A purchase at this price also clears the US$500,000 threshold of Thailand’s Long-Term Resident visa for Wealthy Global Citizens.
