Blue Lagoon Silica Hotel is located in Sandhnjúkahraun at Svartsengi on the Reykjanes peninsula. The project combines hotel accommodation, wellness facilities, and clinical treatment spaces within a low-rise structure carefully embedded in the surrounding lava field. Originally developed as a geothermal clinic in cooperation with the Icelandic Health Authorities, the building extends the experience of the Blue Lagoon through a quieter and more intimate setting rooted in the volcanic landscape.

The architecture is conceived in direct response to the site and the unique qualities of the Blue Lagoon itself. Mineral-rich geothermal seawater, pumped from deep below ground by the nearby geothermal power plant, forms the foundation of both the spa experience and the architectural concept. The dramatic contrasts between black lava, steam, milky-blue water, and the shifting Nordic light shape the atmosphere throughout the project.

The building sits low within the rugged moss-covered terrain, which is intentionally left largely untouched around the structure. The architecture establishes a dialogue between geometric clarity and the irregular organic forms of the surrounding lava field. Hotel rooms overlook the landscape and open onto private patios, while sheltered courtyards provide contrast to the exposed volcanic environment beyond.

Material choices reinforce the relationship between architecture and place. White rendered walls reference the silica and salts of the lagoon, while lava-coated concrete surfaces connect directly to the dark volcanic surroundings. Steel and timber elements introduce warmth and precision within the otherwise raw setting. Large glazed openings frame views of the landscape and allow daylight to play a central role in the experience of the building, where changing weather and light conditions continuously transform the atmosphere of the interior spaces.
