we do in guest bedroom,, but not sure will go with colors I have picked out, and the great room is a vaulted ceiling ....I guess we will just have to see...our house is being built and will be very open..not alot of wall space.

Perhaps a large round table might mean a rug is not at all necessary. It could be a metal tray table, or carved wood like Rebecca Mitchell Interiors illustrates. Ideas also to consider, using multiple tables can be found at http://www.houzz.com/multiple-coffee-tables. I also agree with comments above that some color is needed on the walls. You could then hang round mirrors, or an unusual curved shape like RMI shows above.

At first glance I think that if you are going for a modern look, I would suggest nesting tables instead of a coffee table to create interest. Here are a few ideas for you: http://deciture.com/the-amazing-set-of-3-wood-nesting-table/ http://deciture.com/gilbert-galvanized-nesting-tables-set-of-3/ http://deciture.com/flouressa-mirror-top-nesting-tables-set-of-3/ http://deciture.com/brighton-mirror-top-nesting-tables-set-of-3/ Hope this helps you!

#1 is the only one that works with your doorways. But I would rethink the sectional pieces which look too large. You will need at least a floor lamp. Your table/chairs looks narrow in relation to your sectional - is it to scale in the drawing? You may not have enough room. I would use a sofa against the wall and two chairs on either end facing toward each other.
