A Kuching home renovation by J Hous Studio reimagines an existing award-winning house in Sarawak into a residence defined by curved architectural details, a restrained material palette, and a considered connection to the outdoors

The owners of a house in Kuching, Sarawak, gave J Hous Studio an unusually open brief. The couple, who have two young children, wanted a transformation that would exceed their expectations. They named Italian luxury minimalism as a reference point and then, by their own account, handed over the rest.

Joyce Wong, founder and lead designer of J Hous Studio, was working with a property that already carried some history. The house had previously received a PAM Architectural Award. She proceeded anyway, and at considerable scale. Walls were hacked, ceilings stripped, all floor finishes replaced. A ground-floor side and rear extension brought the total built-up area from 2,500 to 3,400 square feet.

The physical scope of the work is evident in the finished house, though Wong was more interested in the organisation of space than in its addition. “Rather than relying on physical partitions, we explored how design elements, materials, form, and architectural details could subtly differentiate each zone,” she says. A curved timber platform at the dining area separates it from the living space without enclosing it.

A corresponding curved ceiling sits directly above, and together the two elements establish a spatial boundary that reads as structural. A corresponding language of curved ceiling edges runs across the entire ground floor, broken into different levels to compensate for a ceiling height constrained by the existing first-floor slab. The layering creates depth where a flat plane would have felt compressed.

The material palette is anchored by Arabescato Orobico marble, used throughout the home and extended into the master bathroom, where it is incorporated into the sink design. The kitchen island uses Bianco Carrara marble — less expressive, more subdued — as a visual counterweight. Teak wood covers the ground-floor platforms and the entire first floor.

The staircase moves through three materials across three steps: trowel stone cladding, then Arabescato Orobico with curved edging, then teak. Cabinetry and wall panels in the common areas are finished in oak tones; the master bedroom shifts to walnut, marking the move from shared to private spaces.

A structural column in the dining area was an early problem. It fell within the dining table’s footprint and compressed the usable layout. Wong designed a custom table with an irregular, organic form that works the column into its composition rather than around it. The table surface is finished in anti-scratch stainless steel; one leg is curved acrylic, reducing the visual weight around the column. “The column no longer feels like an obstruction,” Wong says, “but becomes part of a cohesive design feature.”

At the rear of the ground floor, large folding doors in the dining area open onto a landscaped garden with a fish pond along the side of the house. A slide-up window between the wet kitchen and the dining area allows food to be passed through directly, and a garden bar counter extends the serving sequence outdoors.

The fish pond circulation system and select garden lighting are solar-powered. “When meals are prepared, they can be conveniently passed through this window directly to the dining space,” Wong says. “This seamless flow between spaces encourages a more social and interactive lifestyle.”

Cross-ventilation was built into the layout through the folding doors, a side folding-up window, and strategically placed sliding doors. When fully open, the configuration allows air to flow through the interior, reducing reliance on mechanical cooling.

The owners have described the house as their forever home, a place where they expect to remain as their family grows.
