Set within the Hyrcanian forests, the lighting design was conceived as an extension of the landscape, preserving natural darkness while providing comfort and safety. By day, curved panoramic glazing and a skylight draw natural light into the cabin and maintain a connection with the forest canopy. After sunset, concealed linear lighting follows interior geometry, softly illuminating ceilings and walls through reflection to reduce glare and create a calm atmosphere. Integrated bedside luminaires provide focused light, while warm points beneath the tensile canopy support outdoor use and circulation. Low-level lighting defines paths, steps, reed fences and structural supports. Illuminated trunk-like elements reinterpret the forest floor as a field of fireflies, creating a distinctive identity without overpowering the setting. From outside, the transparent suspended cabin becomes a softly glowing lantern among the trees, balancing function, visual comfort, efficiency and respect for nature.
