Eucalyptus House

A raw concrete sanctuary framed by the Currumbin Valley canopy.

Brett McDonald · Principal Architect · 2026
In the vastness of a valley, there is a distinct psychological need for a sense of protection. It is a common misconception that a connection to nature requires a lightweight structure. In this design for Currumbin Valley, the architecture does not compete with the forest; it provides a steadfast anchor within it.

A Level Datum in the Landscape

The design presents as a low-profile pavilion that respects the natural fall of the land. By utilising a wide timber deck as a level datum, a man-made plateau is created, allowing for a seamless transition between the built environment and the valley floor. 

Deep roof overhangs are a functional necessity, shielding the interior from the high summer sun while inviting the warmth of winter light deep into the plan.

Structural Sincerity

Board-marked concrete serves as the primary structural spine. This material is chosen for its permanence and its ability to weather gracefully alongside the site's geology. The texture of the timber formwork remains visible on the concrete, a mark of structural honesty that feels both industrial and organic.

It provides the thermal mass needed to regulate the internal climate naturally.  

The Inverted Canopy

The interior volume is defined by a repetitive rhythm of exposed timber rafters. This structural skeletal system acts as an internal canopy, echoing the verticality of the surrounding eucalyptus forest. By drawing the eye upward, the architecture increases the perceived volume of the room, removing the feeling of being "enclosed" and replacing it with a sense of atmospheric scale.

Sanctuary and Stillness

The master suite is positioned to maintain a constant sensory connection to the forest floor. Timber flooring and minimal joinery extend the warmth of the woods into the room, while expansive glazing frames the bushland as the primary protagonist. 

The design suggests that luxury is not found in ornamentation, but in the silence of a framed view and the play of dappled light.

Tactile Contrast

In the ensuite, the density of marble provides a cool, sensory contrast to the warmth of the timber throughout the rest of the home. The material palette is responsive: strong where the architecture meets the earth, and refined where it meets the inhabitant. 

It is a space stripped of visual noise, where the focus returns to the tactile quality of stone and the surrounding greenery.  

The Dissolving Boundary

Large-scale sliding portals allow the social hub to function as an open-air pavilion. When the glass is retracted, the boundary between the kitchen and the external deck effectively vanishes. This layout is designed to facilitate passive cooling, allowing valley breezes to draw through the house, reducing the reliance on mechanical systems and grounding the inhabitant in the immediate environment.

The Principles of Equilibrium

Eucalyptus House is a study in balance. It is a discussion of how architecture can concede to its environment while providing a sanctuary that is both open to the horizon and profoundly secure. By harmonising the weight of concrete with the transparency of timber-framed glass, the design offers a way of living that is passive, quiet, and enduring.
