Modular Building is a construction method where structures are made from pre-fabricated sections, or modules, that are built off-site in a factory. These modules are then transported to the construction site and assembled to create the final building. This approach can save time and reduce waste, as many components are manufactured in a controlled environment. The modular construction process allows for greater flexibility in design and can be used for various types of buildings, including homes, schools, and offices. Additionally, it often results in lower costs and faster completion times compared to traditional building methods.
