Which type of construction allows for the use of any materials permitted by code for both exterior and interior walls?

The type of construction that allows for the use of any materials permitted by code for both exterior and interior walls is Type V construction. This classification is often referred to as "wood frame" construction, which is the most flexible type when it comes to material usage.

In Type V construction, walls can be constructed using various materials such as wood, steel, or masonry, as long as they adhere to local building codes and regulations. This flexibility makes it a popular choice for residential buildings and smaller structures because it can accommodate a wide range of design styles and construction techniques.

The allowance of diverse materials for both exterior and interior walls in Type V enables builders to take advantage of cost-effective options while still meeting safety and code requirements. This adaptability is especially beneficial for builders who want to incorporate modern materials and sustainable practices into their projects, further enhancing the appeal of Type V construction.
