Before delving into the various types of residential building structures, let's briefly understand what a residential building is. A residential building is primarily designed to accommodate families, individuals, or groups of people. The fundamental components of any building, such as the foundation, floors, walls, beams, columns, roof, stairs, etc., work together to support, enclose, and protect the building structure. This structure dictates the stability, design, and overall aesthetic appeal of the building, collectively referred to as the building structure.
