A Siheyuan is a traditional Chinese courtyard house characterized by its rectangular layout. It typically consists of four buildings surrounding a central courtyard, providing a private space for family activities. This architectural style is commonly found in northern China, especially in cities like Beijing. The design of a Siheyuan promotes harmony and balance, reflecting the principles of Feng Shui. Each building usually serves a specific purpose, such as living quarters, kitchens, or storage. Siheyuan structures are often made of wood and brick, showcasing intricate carvings and decorations that highlight Chinese cultural heritage.
