In conclusion, the reason why the facade design became important in Renaissance architecture is because these can recreate the ancient Roman building for example Sant'Andrea. Cheap to change a design or a style of a building for example Santa Maria Novella and Palazzo Rucellai. During that the Renaissance, people create new facade. But now you can't see a lot of facade build. However now I have seen people kept the facade of a really old building as the the face.
