The materials buildings are built from have definitely changed. Before, Thailand used to have houses built on stilts and made of wood, showing off its traditional style of houses that date way back. Now houses in Thailand are much more modern and are built in concrete, cement, glass or bricks. Materials have definitely improved to make sure that the houses are well-built (won’t fall apart), and to ensure the safety of the people living there. Before Thailand wasn’t as dangerous as it is nowadays, so the building structures have changed for the safety of everyone.
