3 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. 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.

4 Simple construction method Simple construction method Upright members: posts, columns or piers Upright members: posts, columns or piers Hold a third member horizontally: lintel, beam, girder or rafter. Hold a third member horizontally: lintel, beam, girder or rafter. In this system acts two forces, compression and tension. In this system acts two forces, compression and tension.

8 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.

9 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.
