High among the towering karri trees of southern Western Australia lies a hideaway that feels both audacious and utterly natural: The Treehouse, Denmark. Located in the leafy suburb of Wheedon Hill, this architectural gem doesn’t just sit in the forest — it is of the forest. Granite boulders pass through floors. Tree trunks bisect rooms. It is, in short, a house that grows with its surroundings, not over them.
You reach it via a softly curving staircase carved alongside a massive granite outcrop — the same rock that eventually thrusts upward through the heart of the living room. In evening light, small LED lights along the steps awaken, and the karri trunks glow gently, turning arrival into a kind of ritual. You feel as though you’re being welcomed into the forest itself.
Stepping inside, a double-height living space opens before you, framed by walls of glass. The layout is open: kitchen, dining, lounge all flow together under one high ceiling. Light floods in, shadows shift as day turns to dusk, and forest becomes your constant view. Yet despite its exposure, the interiors maintain warmth — leather chairs, timber floors, hearths and curated minimalism that invites you to linger rather than escape.
What’s most striking is how the natural lines infiltrate the architecture. That boulder? It anchors you. It becomes part of the room. Sometimes you’ll stop mid-conversation just to lean a hand on the cold stone rising beside you and feel a subtle hum of terrain. The cantilevered deck extends outward, almost floating, granting glimpses of Wilson Inlet and forest canopy beyond.
Inside, comfort isn’t sacrificed for drama. One bedroom sits on the main level; another loft-style bed perches above the living space (accessible by ladder, so fair warning — might not suit everyone). A spacious bathroom includes a spa bath, standalone shower, and large windows that frame branches rather than walls. Heating, cooling, insulation — they’re all modern and effective. The house was newly built, well-insulated, and rated for year-round livability. On cold nights, that wood burner hearth becomes your cornerstone of coziness.
For guests, the Treehouse is a sanctuary. Away from TV (though one is available), your attention gravitates outward — to forest rhythm, to birdcalls, to drifting fog and sunbeams dancing through leaves. At night, the verandah leads to quiet porch spaces where you sip wine, flip through a book, or simply stare outward until you forget where the house ends and the forest begins.
The cost starts around €140 per night, with a recommended two-night minimum if you truly want to slow down and settle in. Stay longer? Rates soften slightly. It’s not cheap, though — but then again, what you pay for here is a rare mix: bold design, deep solitude, narrative architecture in terrain, and all the little comforts that make you stay longer than planned.
The Treehouse sits roughly halfway between Denmark WA and Ocean Beach, making it a perfect base to explore forest trails, the well-loved Green’s Pool, Elephant Rocks, and the Tree Top Walk. After days stomping in bushland or listening to surf, coming home to this elevated retreat feels like returning to your best self — slow, quiet, a little awed.
If you yearn for a stay that doesn’t just show you nature, but lets you live in it, The Treehouse, Denmark quietly invites you in. It’s not perfect — ladders tease you, spiders might visit, rain sings on glass — but in that messy middle between wild and refined, it becomes unforgettable.
