There are many constructive methods and techniques to build any space. Those constructive systems determine and characterize the environment which is located and the personality and needs of the people who will or are using that space In the following presentation we will be talking about "post-and-lintel", describing this method, it's advantages and disadvantages as structural and decorative elements.

Nowadays, most post and lintel construction has a third component, the wall, which adds additional support and hides the post and lintel design within the framework. It can still be seen in doorways and columns, in which the space between the vertical supports is open.

The Post and Lintel offered a solution for constructive problems in the early days, it allowed bigger and stronger buildings to be constructed. Thanks to its simplicity it is still used in modern architecture and the construction systems developed form it, helped us shape the world we live in.
