In a typical residential context, which type of construction would most likely include exterior load-bearing walls made entirely of wood?

In a typical residential context, the construction type that would most likely include exterior load-bearing walls made entirely of wood is wood frame construction. This is because Type 5 construction, which is commonly used in residential buildings, relies on materials such as wood for structural elements, including the load-bearing walls. Wood frame construction is characterized by its use of light-frame wood components, making it efficient and cost-effective for building homes.

In contrast, other construction types have different materials and characteristics. Type 4 (Heavy Timber) utilizes large dimensional lumber for its structural elements but is specifically designed to resist fire better than traditional wood frame construction. Type 1 (Fire Resistive) and Type 2 (Noncombustible) construction types primarily use non-combustible materials, such as concrete and steel, which do not include wood for the primary structural components. Thus, they would not have exterior load-bearing walls made entirely of wood.
