It is usual to use the same hardware on both sides of a door.
Homes usually carry an overall theme like country or traditional for example, therefore, the door knobs won't have a lot of variety.
The house I built is a two story cedar with a wrap around porch in the woods. My theme is country antiques.
I have a brass door know on the front door the style of the 1800's.
All of the rooms connect. When you look from one room into the next, the room looks like it "belongs".
You can see part of my house in the thread
