Khun Atiruj Residence

Ari House is a private residence situated in a dense urban neighborhood, designed with a clear emphasis on openness, calm, and seamless spatial flow. Rooted in the principles of indoor-outdoor living, the architecture creates a quiet sanctuary that balances structural innovation with material warmth. The home responds to the client’s brief for a light-filled, comfortable living environment while negotiating the challenges of a large-span structural grid and urban privacy.

The journey into the house begins through a semi-outdoor arrival court, softly defined by natural textures and filtered sunlight. A large timber door, flanked by warm plaster walls and vertical timber cladding, marks the entry—subtle, grounded, and intimate. Overhead, finely detailed lattice screens offer privacy to the upper levels while allowing dappled light and breeze to penetrate the facade, creating a sense of depth and layering from the street to the interior.

Inside, the heart of the home unfolds into a double-height living space framed by floor-to-ceiling openings that connect directly to a lush backyard. This central volume acts as a social and visual anchor, enhancing spatial clarity and creating a calm continuity between interior and landscape. The use of soft, tactile finishes—plastered walls, timber ceilings, and warm-toned furnishings—further supports the atmosphere of effortless comfort and elegance.

The circulation is intuitively planned: a straight, natural flow from the front arrival space to the private garden at the rear, reinforcing axial views, cross ventilation, and a strong sense of openness. Full-height glazing and operable panels ensure the interior remains visually connected to greenery, while soft curtains and timber screens provide control over privacy and light.

One of the project’s major technical achievements is its 9-meter structural grid, executed using a post-tension concrete system. This approach allows for column-free spaces with expansive ceiling heights, enabling unobstructed views and flexible room configurations. Despite its structural complexity, the system is integrated seamlessly within the design language, with no visible expression of structural burden.

Material selection plays a key role in unifying the house’s architectural narrative. Timber cladding, applied both internally and externally, creates visual continuity and a tactile connection to nature. It wraps walls, ceilings, and even service elements, offering warmth and richness without visual heaviness. Natural light animates these materials throughout the day, changing the ambiance and revealing subtle textures and tones.
