a huge thank you to all the unsung heroes behind our beautiful spaces.

เคยมีคนกล่าวไว้ว่า... รอยเปื้อนใดที่ทำให้โลกนี้ดูสว่างไสวขึ้นได้ ก็คงจะเป็นรอยยิ้มที่เปื้อนบนใบหน้าของคนเรา

“ รอยยิ้ม ” สิ่งเล็ก ๆ ที่เรียบง่าย แต่ทรงพลังในการขับเคลื่อนโลกใบนี้ เป็นความสุขที่ส่งต่อถึงกันได้โดยไร้พรมแดน เพียงแค่เรายิ้มตอบ... ความสุขที่แท้จริงเริ่มต้นที่ตัวเราเอง

high above chidlom, a domestic landscape unfolds as an autobiography written in space.

defined by sculptural silhouettes and a quiet, material-led vocabulary, the interior serves as a tactile record of a life lived across japan, the united kingdom, and north america. the assemblage, curated and anchored by the fluid geometries of barbara barry, is a study in soft layering set against the city’s kinetic skyline.

a sanctuary where global influences find a silent, harmonious permanence.
a love letter to the vessels that hold us.

ep i | the architecture of disappearance

in trat residence, time is not measured by a clock, but by the gradual migration of shadows across raw stone.

hidden within an ancient durian orchard, this dwelling by the studio of chet and apisit tunsakul serves as a love letter to mid-century restraint, filtered through a tropical lens.

the father-and-son duo has realised a ‘transparent envelope’ that enables the structure to breathe in unison with the grove. by eschewing mass, the architecture recedes, inviting the visceral textures of the landscape to take centre stage.

ep ii | rituals of the table

a study in precision and warmth. here, the dining space is curated for the host who treats hospitality as a quiet art form.

it is a sanctuary where the geometry of the place setting meets the effortless flow of the evening—a space defined by the intentionality of gathering.

ep iii | the art of concealment

visual calm is preserved by a seamless expanse of cabinetry, acting as the silent anchor of the home.

by integrating bespoke organisational systems, the mechanics of daily life are concealed. the kitchen is no longer a utility, but a quiet stage for existence.

ep iv | the quiet reunion

a shift towards the sensory. in the bedroom, the digital presence yields a grounded, palpable peace.

the philosophy is simple. in an increasingly noisy world, true luxury is found in the silence. an invitation to be present.

ep v | light moves slowly

in these private volumes, the ritual of cleansing is elevated through material honesty.

bespoke joinery hides the internal services, allowing the room to breathe, undisturbed by the silent mechanics of the home.

ep vi | 1,500 stories high

"in my library, i find myself." ~goethe

while a home is built of matter, it is animated by breath and paper. centred around a private collection of 1,500 volumes, this sunlit sanctuary serves as the intellectual heartbeat of the residence.

ep vii | a natural alignment

there is a profound realisation when interiors finally settle into their rhythm. it is the moment where design meets its environment in perfect equilibrium.

we acknowledge the meticulous craftsmanship of the local artisans and the collective dedication to the craft that brought this elemental vision to life.

ep viii | the human element

the true completion of architecture is not the final stone laid, but the first breath drawn within it.

to see these spaces animated by the lives of dr kittiphun and khun wirawan khongsawatkiat is the ultimate reward. it is a sanctuary for shared moments... a labour of love.

A balanced retreat where every detail is designed for peace. Soft, natural light filtering through bespoke wooden shutters meets a tranquil garden view to create a private haven—a place to recharge and find stillness. 🌿

In a world of AI-generated art, there's nothing quite like a hand-painted rendering to bring a vision to life. We’re grateful to still get our hands dirty with watercolours and pencil, meticulously crafting every detail.

It's a beautiful reminder of where design began, and the human heart behind the creative process. 📐✏️📏
