Turf houses are traditional structures built using layers of turf, which is a type of grass and soil. These houses were commonly found in Iceland and other northern regions, where wood was scarce. The thick walls made of turf provide excellent insulation against cold weather, making them suitable for harsh climates. The design of turf houses often features a low profile with a grass-covered roof, blending into the surrounding landscape. Inside, they typically have a central hearth for heating and cooking. This architectural style reflects the adaptation of early inhabitants to their environment and available resources.
