A Geothermal Retreat in Iceland Shaped by Darkness, Steam and the Northern Sky

Embedded within Iceland’s volcanic landscape, Hotel Nótt creates an intimate retreat shaped by geothermal warmth, darkness and the changing northern sky.

Set within a remote volcanic landscape in southern Iceland, Hotel Nótt is conceived as a collection of spaces positioned between the earth and sky. Rather than creating a singular hotel building, Norður Atelier divided the retreat into a series of low basalt volumes partially embedded within the terrain. Dark exterior walls, planted roofs and sheltered pathways allow the architecture to remain visually connected to the surrounding lava fields. At the centre of the property, a sunken geothermal courtyard forms the social heart of the hotel. Steam rises from a series of warm mineral pools surrounded by basalt walls, protecting guests from the region’s powerful winds while maintaining uninterrupted views of the sky. The main lounge and restaurant occupy the largest volume. Floor-to-ceiling glazing frames the distant Icelandic landscape, while smoked oak, textured concrete and dark lime plaster create a warm, restrained interior. Guest suites are distributed across smaller earth-sheltered structures connected by enclosed glass passages. Each room is oriented towards a specific landscape condition, from distant mountains to open lava fields. Geothermal energy provides heating and hot water throughout the retreat, while high-performance glazing and the thermal mass of the partially buried structures reduce energy demand. After sunset, Hotel Nótt transforms. Exterior lighting remains deliberately minimal, allowing the architecture to recede into darkness. The result is a retreat defined by elemental contrasts—cold air and geothermal water, darkness and interior warmth, heavy basalt architecture and the vast, constantly changing Icelandic sky.
