The building type characterized by exterior masonry walls and interior wood floors and roofs is classified as ordinary construction. This type of construction typically features walls made of non-combustible materials, such as brick or block, while the interior structural components – including floors and roofs – are made from combustible materials like wood.

Ordinary construction is often found in older buildings and residential structures, and it presents certain firefighting challenges due to the combination of masonry and wood elements. The masonry walls provide some fire resistance; however, the wood components can contribute to rapid fire spread once ignited.

Understanding this is crucial for firefighters and strategists in determining appropriate tactics for fire suppression, overhaul, and rescue operations in such structures. Identifying the characteristics of ordinary construction can help in assessing the potential risks involved and developing effective firefighting strategies tailored to the building's design.
