In the ancient Rome period they spread art and civilization. They took existing building styles and went further. A lot of the styles were adapted from the three greek orders. What I find very interesting is that they discovered concrete and this allowed them to get creative. They were able to create arches and domes and pretty much any kind of structure because of their discovery of concrete. The Colosseum was made of concrete and stone. In class we learned that the Maison Carre is one of the best examples of a Roman temple. You can see the Corinthian style that they used for their columns.
Ancient Rome interior design included mosaics and stucco.
They also had flat or vaulted ceilings.
How this style might be used in modern architecture:
Below is an example of a couch used in ancient Rome and a style of furniture that we use in modern design
Something I found that I thought was very interesting that is a modern design is this photo below. You can see the desk style and the style of the shades are adapted from ancient Rome design.
