Roundhouses are circular structures traditionally used for living or storage. They are often made from materials like wood, stone, or thatch, depending on the region and available resources. The design allows for efficient heating and ventilation, making them suitable for various climates. Roundhouses have been used by different cultures throughout history, including the Celts in Britain and Native American tribes. These buildings typically feature a central hearth for cooking and warmth, with a roof that slopes down to the walls. The round shape promotes a sense of community, as the layout encourages social interaction among inhabitants. Today, roundhouses are sometimes used as eco-friendly homes or cultural heritage sites.
