Here in Thailand, most villas are constructed of concrete and steel. They use a post and beam structure of reinforced concrete with brick and mortar walls. Pilings are set into the ground and tie into a substructure that supports the villa.
The structure of the villa will last far longer than the economic life of the individual components. This type of construction is strong but the main reason they use it here is because of the weather. The question of “useful life of a Villa” sometimes comes up in conversation.
Over time, due to wear and tear, those individual components beak down and need repairs or replacement. Knowing the age of a villa will give you an idea when they’ll likely need maintenance and replacements again.
