Why is Type 5 construction commonly used for family homes?

Type 5 construction, often referred to as wood frame construction, is commonly used for family homes primarily due to its cost-effectiveness and the use of combustible materials, which facilitates easier and quicker building processes. This type of construction utilizes light wood framing, making it less expensive than other types that require heavier or non-combustible materials. These materials, while classified as combustible, allow for straightforward assembly and accessibility.

Many residential builders and homeowners favor this construction style because it tends to provide sufficient structural integrity for family homes while remaining economically viable. The lower cost and availability of materials contribute significantly to the popularity of Type 5 construction in residential developments.

In contrast, other types of construction, such as those that include heavy structural components, are typically used for commercial buildings or structures that demand higher durability and fire resistance. Additionally, high fire ratings and complex engineering requirements are more often associated with Type 1 or Type 2 constructions, which are not practical or necessary for most family home designs.
