I don't these two style of columns are in conflict with each other, as there are enough square and rectangular components in the base of the columns and also the bookcases that will replicate a more craftsman style. You might also incorporate furniture with a similar leg style on dining table or coffee tables so that they are similar to the columns in style.

Why wouldn't you use a more squared column so it matches the style of house? Are you trying to not make it seem like a craftsman inside?

The house is custom and the exterior was based on a picture I found. The inside column room divider was just a different picture I wanted to incorporate. Do you think the square columns would look ok? Mostly I have seen craftsman room divers that have columns do not have an arch.

It's a beautiful home! I think the interior columns you like would look great. This look would harmonize well with the exterior in my opinion. Good luck!

They will do fine.

I think they will look great together!
