Which type of construction is the most common in contemporary buildings?

The most common type of construction in contemporary buildings is Type 5 construction, often referred to as "wood-frame" construction. This is because it utilizes lightweight materials such as wood for framing, which today’s building codes have adapted due to their cost-effectiveness and ease of assembly. Type 5 construction typically consists of combustible materials, making it suitable for residential buildings and smaller commercial structures.

This construction style allows for greater flexibility in design and is often favored in areas where rapid construction is needed. Its prevalence is supported by its ability to create multi-story structures while adhering to modern safety standards and regulations. This type of construction is particularly popular in suburban developments and is associated with a variety of architectural styles, from single-family homes to apartment buildings.

The other types of construction—Type 2, Type 3, and Type 4—are utilized in specific scenarios or for certain types of buildings, but they do not match the widespread use of Type 5 in everyday construction projects today. Type 2 construction, for example, involves non-combustible materials and is commonly found in commercial buildings, while Type 3 and Type 4 constructions introduce heavier materials and specific requirements that may not be as adaptable for contemporary common use as Type 5 is
