HI -- This depends on if your furnishings are going to be traditional or modern . Traditional then yes you could have crown . Modern ,then no to the crown . But blending of these features are being done now to a very nice affect . It's really up to what look your going for . Look for example rooms on Houzz and try this site houseandhome.com . Those floors are beautiful !!

With such a contemporary vibe, crown or base wouldn't be my first choice. Crown and base are both traditional looks.

I would look at doing a ceiling treatment in a color, or a natural material to balance out the strength of the floor. Nothing with a lot of pattern, but a definite presence is required.

How high are those ceilings?

I think it's 9 to 10 feet.

This is an old picture. The floors are all done. And we have a wide flat base board. I was hoping to go with an overall comfortable rustic look with furniture and decor.

If the ceilings are that height, I'd suggest crown molding at the top. It doesn't have to be a traditional sort of millwork design. Choose something like your baseboard--wide and flat. It draws the eye up!

Try cove crown molding. It has a simple, clean line and can be almost any size you want. Paint your wood trim off white and the ceiling bright white to show off your trim.

must do. your floor demands it.

Do the crown molding , most rooms benefit from some architectural detailing.

Definitely crown molding with your flooring.
