Home Tour: Inside the T Pavilion, a 'T-shaped' glass sanctuary in Bangkok where work harmonises with nature

The brief began with Pek’s request for a detached "reception pavilion" separate from the main house—a versatile space for hosting guests, relaxing informally, and working. The architectural team immediately sought a design language that could maximise the potential of the tree-lined garden views.

“We wanted the building to be as transparent as possible to take in all the surrounding views. That’s why we aimed for the absolute minimum number of pillars, ensuring nothing obstructed the scenery,” notes Mark Natthawut Klovuthi-anun, co-founder of Atelier01 (A01). This concept drew heavy inspiration from modernist prototypes like the Farnsworth House in the US, and Mies van der Rohe’s Neue Nationalgalerie in Berlin, renowned for its wide steel spans and minimal columns.

However, translating museum-grade grandeur into a cosy home is no easy feat. The challenge was to distil these imposing proportions into a relaxing residential scale. The solution lay in the interplay between natural light and negative space—two elements Pek values highly.

“I am a huge believer in natural light,” Pek adds. “I feel that working with natural light allows thoughts to flow more freely. It helps you think outside the box because there are literally no boxes enclosing you.”

This sentiment became the pavilion's heartbeat. By reducing columns and beams until they nearly vanished from sight, the architects created an environment where one feels as though they are sitting directly in the garden, albeit shielded from the elements.

Beneath the illusion of a weightless, structure-free glass box lies an incredible feat of advanced engineering. The entire pavilion is supported by just four steel pillars, holding up a sprawling 16-metre roof. The architects concealed triangular steel trusses within the roof canopy to keep the living area as free of visual obstructions as possible.

“At a glance, everything looks incredibly simple. But in reality, every detail was meticulously calculated to hide the necessary systems and only showcase what is essential,” Mark explains. A prime example is the slatted teak ceiling; there are no unsightly air-conditioning vents or access panels in sight. Instead, the design team engineered the wooden grooves to act as built-in vents, with service points cleverly hidden behind tiny, almost imperceptible wooden pegs.

This level of precision is a testament to Pek’s extraordinary eye for detail.

“Mark knows I’m quite particular,” Pek laughs. “If you look at my wardrobe, everything is colour-coded and perfectly in its place. Their attention to detail actually exceeded my expectations.”

Another highlight is the bespoke "curved corner glass". Pck specifically requested this modification from the standard right-angled corners.

“A standard glass partition line can block your view of a beautiful tree. By curving the corners instead, we get an uninterrupted view, which naturally makes the space feel airier,” Pek notes. The result is a seamless panoramic view, free from silicone joints or steel frames, elevating the act of "looking out" into a deeply immersive natural experience.

The project’s moniker, “T Pavilion”, is derived from the distinctive T-shaped steel joints connecting the roof to the pillars. But what truly sets this structure apart is the deliberate decision not to place pillars at the corners.

“Traditionally, pillars sit at the corners of a building,” Mark explains, discussing their unconventional approach. “But to open up the angles, we extended the roof outwards and pushed the pillars towards the centre.”

Moving the pillars inward not only gives the roof overhang a beautiful, floating quality but directly enhances the user's experience. When the frameless curved glass meets a pillar-less corner, the eye is drawn endlessly outward into the greenery.

“The T-structure enhances connectivity whilst remaining incredibly aesthetic,” Mark concludes. The framework acts as both the building's spine and a massive picture frame, seamlessly inviting the garden landscape into the interior.

Inside, the T Pavilion utilises an open-plan layout, entirely doing away with solid dividing walls. The space is organically zoned through furniture placement and varied ceiling heights, allowing for a fluid transition from work to relaxation.

“In a single day, this space might serve four different functions. Breakfast in the morning, a work meeting before noon, hosting friends for lunch, and watching football or a film late at night,” says Pek.

Despite its stark modernism, the T Pavilion possesses a deeply familial heart. A simple yet challenging brief for the architects was the inclusion of a dining table large enough to seat 12 people.

“Pek told me, ‘I need 12 seats because there are 12 of us in the family. When we eat, we all need to sit together,’” Mark recalls. This requirement transformed the pavilion from a solitary retreat into a genuine family hub.

Furthermore, the wall-less interior champions universal design. The inclusion of wheelchair-friendly ramps rather than steps ensures that elderly family members can navigate the space with ease. It is a welcoming environment where the entire family can gather and unwind.

“I’m not a fan of brands that shout their logos, whether it’s in fashion or furniture. We choose things for their texture and the quality of the materials,” Pek says, perfectly encapsulating a philosophy of quiet luxury. This is evident in his selection of premier Italian furniture from Poliform and Poltrona Frau.

A standout piece is the Brera Sofa from Poliform. The architects opted for fabric upholstery over leather for a warmer, more inviting tactile experience—ideal for long lounging sessions. Nearby sits the Times Lounge chair by Poltrona Frau, custom-upholstered in bespoke Loro Piana fabric to perfectly match Pek's desired tone and feel. As Mark notes, these pieces are truly timeless: “Some of these designs are ten years old, yet they look as though they were conceived yesterday.”

This devotion to material excellence extends into the pavilion's most private sanctuary: the bathroom. Designed in a circular motif to echo the curved exterior glass, its crowning jewel is a bespoke natural marble washbasin. It required the dedicated effort of 2–3 artisans, hand-polishing the stone for over two weeks, to achieve its flawless form.

“This basin isn’t just about beautiful marble veining; it’s highly functional. The water drainage slopes and the maintenance systems were rigorously planned,” Mark shares. “We wanted it to be an iconic centrepiece. Even as a solitary object, it is instantly captivating.”

While the 360-degree glass exterior might suggest a lack of privacy, the design team brilliantly mitigated this through strategic site planning, pillar placement, and the use of granite feature walls. These act as visual filters from the outside, subtly guiding visitors before opening up into the expansive interior.

For Pek and Atelier01, the creative journey doesn't end here. They are currently quietly developing a new, larger-scale urban project that promises to be even more challenging. It will undoubtedly serve as another testament to the fact that when a passion for perfection meets visionary architecture, a space becomes far more than just a building—it becomes a truly meaningful home.
