PROS would be: - Symmetrical interior design is a perfect for traditional styles. - With such balanced room you can feel confidence, tranquility, and safety. - These interiors will appeal to people who are prone to perfectionism and conservatism. CONS would be: - This plan is often not suitable for small rooms. - The regular arrangement of elements along the central axis emphasizes the shape and size of the room. For example, if the room is narrow and long, the symmetrical order will make the room look like a trailer.
