Painted Arches
You can use different methods to make rooms look bigger than they are. A current popular method is painting arches and adding mirrors to create the optical illusion of more space. However, this trend might not last long!

It doesn’t make sense to paint an archway in a room that doesn’t have a doorway. It may appear attractive now, but the color will fade with time, and you’ll have to restore it, which is just more work than it’s worth.
