Perched in the canopy above the Vazak Mountains near Royan, in Iran's Mazandaran Province, Tree House makes a quiet but definitive architectural statement. Rather than planting a footprint into the forest floor, architect Pedram Shaygan and Farid Ebrahimi of Naghshe Khak Architectural Group lifted the structure into the trees. Completed in 2018, the 45-square-meter retreat sits at trunk level, where the views open across the valley and the forest keeps its roots undisturbed beneath you.

The decision to build upward shaped every other design choice. Before any bracket was drawn, environmental specialists assessed the host trees — their age, their health, their load-bearing capacity. Only then did the team commit to non-invasive anchoring hardware that distributes weight without biting into living wood. Trees remain trees, not structural columns. That single principle gives the building its character more than any surface finish could.

Dark-stained timber cladding draws the exterior into the surrounding foliage, allowing the structure to recede rather than announce itself. The geometry follows suit. Shaygan works with broken and sloped planes — angles borrowed from branches, edges that catch light the way a bough does at dusk rather than cutting across the landscape. The result feels like a continuation of the forest rather than an interruption of it. Local materials keep the supply lines short and the finishes weathering naturally into the setting over time.

Two levels divide the experience clearly. The lower covered deck works as an open-air living room: shaded, breezy and wide enough to take in the valley from a reclining chair. Climb to the upper level and the mood shifts inward. A compact living room, wood-burning fireplace, small bathroom and large windows make up the interior. Those windows frame the forest like a slow, changing painting — nothing dramatic, just the kind of view that keeps you seated far longer than planned.

The season shapes what you find here. Summer, from June through August, brings mild highland air, clear skies and ideal conditions for hiking and sitting out on the deck long into the evening. Autumn turns the northern forests gold and misty, and the cooler temperatures make the fireplace feel earned. Spring arrives vivid and green, with wildflowers and rushing rivers. Even winter offers something — dramatic cloud cover rolling over the Alborz foothills, and the rare pleasure of a snowbound forest canopy with a fire burning inside.

Tree House suits travellers who care how a building sits in its landscape. Architecture enthusiasts, slow travellers drawn to the forested highlands of northern Iran, and anyone who has grown tired of accommodation that ignores where it stands will find this retreat genuinely rewarding. It was designed as a private ancillary hideaway, and that intimacy comes through in every detail — the scale, the materials, the hush. This is a building that listened to the forest before it answered. The experience carries that quality throughout.
