扩建

扩建 refers to the act of expanding or enlarging a building, structure, or facility. It typically involves adding new sections or increasing the size of an existing one, often for functional or operational reasons.

The character 扩 (kuò) means 'to expand' or 'to enlarge,' while 建 (jiàn) means 'to build' or 'construction.' Together, they form a term that specifically describes the process of extending or upgrading existing structures.

扩建 is commonly used in contexts such as urban development, architectural planning, and infrastructure projects. It is often contrasted with 新建 (xīn jiàn), which means 'new construction.' Understanding this term is useful when discussing building projects or real estate developments in Chinese-speaking regions.
