Oriental culture is based on the use of natural materials. For the reason, the Thai decor makes heavy use of wood, being the main and fundamental element of any environment that has this style.
Importantly, Thai decor was eventually merged with other trends. They made their style was upgraded to become what we see in most of the photos that accompany this entry. The low use of furniture, plus the great enlightenment, as a result, provide very striking interior design, which keep the mystique of the past.
In many environments that have an authentic Thai decor, we see significant colorful wood furniture with hand carved details. The work we have that furniture is entirely handmade and given this their costs are very high. This is why Thai interior design is not for everyone. It requires a large capital to provide an environment of this type of furniture.
What no one can ever deny is that this type of environment as well as with any trend of Eastern culture (such as Japanese interior decoration), have a warmth and peace spread incredibly.
