Minecraft wiki entry for Building_a_metropolis, associated text: Ethnic City: Base your domain around traditional architecture employed by a country or ethnic group. Every country or group has its own style of architecture, with East Asian and Western European architecture being probably the most well-known styles. For example in traditional Japanese architecture, wood is the most common material, whilst roofs are often tiled or thatched, and buildings are elevated slightly off the ground. In traditional Chinese architecture, wood is also a common material, and buildings are typically bilaterally symmetric and feature enclosed open spaces.
