The Dimmuborgir site near Mývatn Lake and Hverfjall volcano takes its name from the Icelandic word for Dark Castles or Dark Cities, and was formed some 2,300 years ago by a massive eruption that created the unique features and bleak landscape. As lava flowed across the marshland, the water boiled and vapour began to rise through the lava. This created the lava pillars that vary in size from a few centimetres to towers that stretch several metres in diameter. Unique texture of this rock formation was an inspiration for us to base entire idea of the project. Scaled pumice texture and rock foam-like structures have their abstract imprint in spatial distribution, function relationships, elevation textures and building structure itself. Materials that we have chose are concrete, metal, timber and glass, to match roughness and simplicity of Icelandic landscape.
