A Japanese, Chinese, and European style courtyard plan refers to a landscape design that incorporates elements from these three cultural traditions. It typically features Japanese Zen garden principles with elements like raked gravel, rock formations, and minimalist design. Chinese gardens often include a harmonious blend of nature, with elements such as ponds, bridges, and pavilions. European gardens might include formal layouts with hedges, topiary, and symmetrical flower beds. These plans blend these elements to create a unique and culturally diverse outdoor space.
