House on the Hill

Anchored within Brigadoon’s undulating terrain, The House on the Hill resists the ordinary through a quiet yet deliberate assertion of presence. Poised between landscape and sky, its silhouette reads against the sweeping panorama of the Perth city skyline as a restrained emblem of architectural clarity. Informed by the sinuous rhythm of the native millipede, the form folds and extends through a sequence of measured gestures, fusing structure and inhabitation into one continuous motion. Precisely oriented, the architecture is drawn instinctively toward light, tracing a calibrated dialogue, where landscape, horizon, and inhabitation resolve as one, continuous and quietly monumental.

This project is an exploration of instinct, memory, and land, where architecture emerges through observation rather than imposition. The site operates simultaneously at two scales: expansive valley and city vistas stretching into the distance, and a dense, intimate bushland condition pressing closely from behind. Across a dramatic 64-metre fall from ridge to valley floor, the terrain asserts itself as a defining force, shaping not only form, but experience.

The genesis of the design lies within a habitual routine. The clients would bring family to the property, sitting together on a large rock as twilight fell, watching the city lights begin to shimmer below. This act of quiet observation revealed a deeper parallel within the site’s ecology. Indigenous millipede species found within that region are uniquely drawn to light at night, pausing in stillness to orient themselves toward illumination. Human and nature, unconsciously mirroring the same behaviour. That shared instinct became the conceptual anchor for the house.

Rather than resolving the extreme slope with a long, linear and parallel structure, the building adopts a civic clarity informed by biomimicry. When dissected, the millipede reveals a radial grid, articulated through subtle eight-degree shifts between segments. When curled, it never resolves into a perfect circle, but a controlled, imperfect arc. This geometry was abstracted, arched, and deployed as the organising framework for the upper level, allowing the house to bend with the land rather than resist it.

This radial system also generates moments of compression and release. Along the rear façade, small apertures puncture the building, offering fleeting glimpses of dense vegetation as one moves through corridors. These are deliberate pauses, micro encounters that contrast the expansive valley views beyond. All primary rooms are oriented toward the city and valley, many layered with views to the swimming pool, ensuring a continuous visual dialogue across landscape, horizon, and domestic life.

Arrival is intentionally understated. The steep terrain refused conventional entry, prompting the creation of an intermediate landing carved into the hillside. Drawing from ancient tombs, museums, and cave-like thresholds, the entry is a restrained, almost primitive form curved into the architecture. From this point, the house presents a choice: ascend or descend, each path revealing itself with equal clarity.

Descending unfolds into an open kitchen and dining space that extends seamlessly to terraces, outdoor living, pool, and landscape beyond. A sunken lounge preserves uninterrupted sightlines, allowing the horizon to remain dominant. Rock unearthed during excavation was retained and exposed wherever possible, creating the illusion that the house is not placed upon the site, but emerging from it.

Internally, a dark, moody palette reinforces the concrete and rock vernacular, heightening contrast with the living landscape outside. Spaces shift in perspective, each framing the land differently. When read as a whole, the architecture resolves into a singular, legible idea: a millipede resting on a rock, quietly gazing toward the evening lights. Architecture shaped by instinct, grounded in place, and inseparable from its environment.
