Eliza Blair Architecture Builds a Forever Beach House from Rammed Earth and Coastal Air

The forever house is a dangerous brief. It invites overdesign, oversizing, and the kind of anxious future-proofing that produces homes no one actually wants to live in. Eliza Blair Architecture sidesteps all of that at Barwon Dunes House by anchoring the design in two commitments: rammed earth walls that will age with the family, and a plan that separates generations without isolating them. The result is 724 square metres of house that feels loose and lived-in, not monumental.

Sitting a short walk from 13th Beach in Barwon Heads, the house wraps a curved timber-battened upper volume around a grounded rammed earth base. The curve is not decorative. It responds to the corner condition of the site, redirecting views and catching the ocean breeze that cross-ventilates the interior. Every material choice here, from the stratified earth walls to the vertical timber screening, is calibrated to weather rather than deteriorate. The house is designed to look better in twenty years than it does today.

A Base of Earth, a Crown of Timber

The material logic of the exterior is binary and legible. The ground floor is rammed earth: heavy, warm, horizontally striated, and rooted to the sandy coastal landscape. The upper floor lifts off in vertical timber battens, lighter in both color and visual weight. Where these two systems meet, the building gains its tension. The junction is handled cleanly, with the timber wrapping around the entry corner in a generous curve that softens what could have been a blunt volumetric collision.

The slatted gate, the planted beds of ornamental grasses, and the rammed earth boundary walls all conspire to make the street-facing elevation feel settled rather than defensive. You know what this house is made of before you step inside, and that material honesty carries through every threshold.

Living at the Heart of the Plan

The kitchen and dining areas occupy the center of the ground floor, functioning as the gravitational core for a family of five. A curved rammed earth island anchors the kitchen, its mass contrasting with the lighter vertical-grain timber cabinetry that lines the perimeter. The ceiling is clad in wide timber planks that run continuously from the kitchen through the dining space, pulling these zones together into a single spatial experience even as the rammed earth walls subtly define each room.

The dining area pairs an oval table with a large pendant and the ever-present rammed earth walls, creating a room that reads as both generous and enclosed. A horizontal window above the kitchen bench frames a strip of greenery, keeping the garden present without surrendering privacy. The material palette, travertine, timber, earth, stays deliberately restrained, allowing textures rather than colors to do the work.

Rooms That Breathe Apart

One of the smartest moves in the plan is the strategic separation of the games room and guest wing from the main living areas. The games room, visible through full-height sliding glass doors that open onto a planted courtyard, is close enough to feel connected but buffered enough to contain noise and activity. For a house designed to accommodate growing children and visiting relatives, this kind of zoning is essential. It allows simultaneous uses without conflict.

The dining room opens directly to a courtyard through generous glazing, and a rammed earth fireplace wall with linen curtains creates a soft visual screen between living and dining zones. These are not hard partitions. They are material thresholds that suggest separation without enforcing it, a strategy that keeps the plan flexible as the family's needs shift over time.

Courtyards and the Garden Threshold

The outdoor rooms are as carefully composed as anything inside. Rammed earth walls extend into the landscape to frame courtyards planted with native coastal grasses, creating sheltered pockets that feel both wild and deliberate. A steel pergola wrapped in climbing vines shades an outdoor dining terrace, offering a third eating zone alongside the interior kitchen and dining room. The vine growth is a slow-motion design decision: the pergola will become more beautiful and more useful as the plants mature.

The relationship between interior and garden is mediated by a series of glazed doors set within deep rammed earth reveals. These openings frame views of gravel paths and ornamental grasses, collapsing the distance between inside and out while the thick earth walls maintain a sense of shelter. It is a house that breathes with the coastal breeze without feeling exposed.

Circulation as Experience

The corridors and staircases at Barwon Dunes House are not leftover space. A hallway lined with rammed earth walls and timber ceiling planks terminates at a curved bench holding a ceramic vessel, turning a passage into a moment of pause. The staircase, a folded steel structure rising between board-marked concrete walls, introduces a harder material register that contrasts with the warmth elsewhere. The metal balustrade reads as precise and industrial against the organic striations of the earth walls.

The entry vestibule sets the tone immediately: timber-lined walls and ceiling compress the space before it opens into the double-height living room beyond. Woven baskets sit beneath a bench, grounding the arrival sequence in the same relaxed domesticity that governs the rest of the house.

Upstairs: Privacy and Filtered Light

All bedrooms and a work-from-home space are located upstairs, cleanly separating daytime communal life from nighttime privacy. The study desk curves along a wall of vertical timber screening that filters dappled light across the workspace, a condition that changes throughout the day as the sun moves. It is a small detail that makes remote work feel less clinical and more connected to the rhythms of the site.

The bedrooms are treated with restraint. Sheer linen curtains soften the daylight, and the palette shifts to white walls that let the quality of the light become the primary material. After the rich earthiness of the ground floor, the upper level offers a kind of visual quiet. The staircase, with its rammed earth wall and timber ceiling, provides the transition between these two registers.

Detail and Materiality Up Close

The material intelligence of the project is clearest at the junctions. A travertine island bench meets a timber stool with exposed leg joinery, and the two materials acknowledge each other without trying to match. A built-in rammed earth bench integrates seamlessly with the wall behind it, its horizontal striations continuing unbroken, turning furniture into architecture. In the bathroom, olive green mosaic tile and a travertine countertop introduce the only real color in the house, and it works precisely because everything else is so restrained.

The bathroom window, with horizontal louvered shutters opening to greenery, is a perfect example of the house's passive design strategy in miniature: ventilation, privacy, and a view of the garden, all resolved in a single element. Nothing here is arbitrary.

The Double-Height Room

The double-height living space is the spatial centrepiece of the house. Rammed earth walls rise the full two storeys, their layered strata amplified by the vertical scale. Suspended pendants drop into the void, and a timber-clad balcony from the upper level overlooks the room, connecting the private upstairs world to the communal ground floor. It is a generous gesture in a house that otherwise favors intimacy, and it gives the family a space that can absorb large gatherings without feeling strained.

The entry vestibule, timber-lined and low, makes the release into this tall room feel earned. It is a classic architectural sequence, compression followed by expansion, but it works here because the rammed earth provides continuity between the two conditions. You are always aware of what the house is made of.

Why This Project Matters

Barwon Dunes House offers a convincing argument that the forever house does not need to be neutral or generic. By committing fully to rammed earth as both structure and expression, Eliza Blair Architecture has produced a home with a strong identity that is also genuinely flexible. The zoning of the plan, separating communal and private, adult and child, work and play, is done with enough subtlety that the house can adapt without renovation. Rooms have character but not fixed purpose.

More broadly, the project demonstrates that coastal Australian housing can move beyond the white-rendered-box-with-bifold-doors formula without resorting to pastiche or nostalgia. The rammed earth, the curved timber battens, the native garden, and the passive ventilation strategy all belong to this specific site and climate. Nothing has been borrowed from a mood board. The house earns its place in the dunes, and it will only look more at home as the years pass.
