Building is a process where people use materials like wood, metal, and cement to make structures like homes, stores, and bridges. Building involves a lot of planning and designing so that the structure is strong and safe. People use tools and machines to put the pieces together and make sure everything is done properly. You need many people to do the building, like architects to design, laborers to carry the materials, and electricians to install the wiring. Then the building gets inspected to make sure it's up to safety standards. Building can take a lot of time and money, but the results can make our lives much easier!
