Kebagusan House

Residential2024
Street facade of Kebagusan house, timber vertical slats over pale render with a stacked-stone base and a folded concrete canopy.

Two plain masses split by a garden at the center, where a wall can vanish entirely and let the forest step inside.

On a shared family plot in a dense southern suburb, Sepat House splits into two masses and sets a garden in the gap between them. That garden is the canon of the design: every path passes it, every room borrows it as a view, and all circulation benefits from the light and air it draws deep into the plan.

The plot is shared with family, and the architecture negotiates that closeness with care. Turned inward, the two masses hold their privacy from the street while staying open to the shared yard — close enough to talk, separate enough to breathe. Privacy is an orientation, not a wall.

Detail of the split-level facade where a stone-clad living room opens beneath overlapping timber and render volumes.
Corner view of the two-storey facade, a slatted timber balcony and full-height sliding glass beneath a cantilevered upper floor.
Evening view of the entry courtyard, uplit stone walls and a timber-screened porch beside a raised lawn planter and boulders.
Bedroom desk beside a sliding glass door onto a private balcony, its wood-slat screen reflected in the glass.
Landing at the top of the stair, timber slat cladding and a glazed door opening onto the courtyard below.
Primary bedroom with a floating timber headboard, layered bedding, and sliding doors framing an ornamental grass planting.
Bedroom seating corner with a woven armchair beside a low media console and a courtyard-facing window.
Ensuite bathroom in speckled terrazzo, a round mirror over a black vessel sink and patterned tile underfoot.

The large window onto the inner court opens fully rather than partially, so the wall between living space and garden can be removed altogether — the planting stops being framed and becomes continuous, and the room reads as a clearing with a piece of forest held inside the house. It is the ventilation strategy too: air crosses the deep rooms and leaves upward through the void. At the front, a screening layer cuts the direct sun before it reaches the glass.

The volumes are square and plain, held in grey, white, and dark wood — neutral surfaces that let the garden supply all the colour. But that plainness is a foil for quiet surprises: a reflecting pool set beneath the stair, and a living room that lifts into a double-height void where daylight falls from above. Sepat House looks not outward for space but inward.

Double-height void looking down through the stair opening onto a rattan chair and the courtyard deck below.
Entry hallway with a wall-mounted bench and dark timber slat flooring leading toward the living room's glass partition.
Dining table set beneath a double-height void, with the living room's bookshelf and sofa visible past a slatted screen.
Open kitchen in oak veneer with an integrated fridge and a marble island extending into the dining table.
Walk-in closet lined with mirrored wardrobe doors, an upholstered ottoman centred on the runner toward a garden window.
Living and dining area opening through a pivoting glass door onto a planted courtyard with a rattan chair.
