Paris-based firm Atelier LAVIT just unveiled a beautiful treehouse with a surprisingly sophisticated twist. The octagon-shaped Origin Treehouse wraps around a hundred-year-old oak in a lush canopy of treetops. While some treehouse designers take a more rustic approach to their interiors, the French architects went another route, creating a living space that provides hotel-like comfort – and it even features a heated spa and lounge area.

The Origin Treehouse consists of two structure: a platform with a heated spa and a lounge area that sits on a lower level. The second structure is a soaring “birds nest” that’s hidden by the lush foliage. High up in the trees, the 250-square-foot treehouse is accessed via a suspended walkway from the first platform.

Two large sliding glass doors open up to the living space, whose sophisticated design is certainly unique in the world of treehouses. The interior was based on the principles of hotel design: it’s simple, elegant and clutter-free. The interior walls are lined with light poplar panels, giving the space a clean, bright feel. Just past the living space lies a small sitting area, a bedroom, the bathroom, and a technical closet.

The octagonal shape of the treehouse allowed the architects to install plenty of large windows, which flood the interior with natural light. Those wanting to get even closer to nature can take a wooden ladder from the back deck to a stunning rooftop terrace that provides panoramic views of the forest.

According to the architects, the cabin’s unique design was meant to blend into the serene forestscape: “Origin Tree House discreetly stands out among the centenarian oaks of the Château de Raray forest, as if it had always been part of the scenery. Majestic and elegant, it integrates and completes an already impressive landscape, sublimating it by offering a shelter.”
