Bonnie, I have an open floor plan from the LR to the DR. They are right across from each other and only separated by a walking path to the FR. I live in a 2300 sq. ft townhouse. I have wood floors going through 90% of my home. I don't follow many rules of thumbs when decorating but for this one: with solid wood tables use a solid rug. With a glass table always use a patterned rug. You don't have to have a rug in every room. Here is the reason: A glass table can be seen thru and you can actually view the beauty of a patterned rug at any angle. You can't do that with a wood table. Besides, wood tables give a warm feeling on their own. My feelings for eating areas is to use no rug since crumbs (people have the tendency to step on them once they drop) and spills do happen. But that's me. Many on this forum would disagree.

It looks like moving the couch to the window wall will block the traffic from the bedrooms. If there is room, I would try the couch forward of the window wall and perpendicular to the wall with the bookcase so that it acts as one side of a "hall" from the bedrooms to the kitchen. Possibly use the buffet piece, or bookcase if it's low, behind the sofa. Place the chair in a right angle to one side of the sofa. Another arrangement would be to place the couch on the wall shared with your bedroom, TV and storage on the long wall, chairs across from couch. Computer to the left of the window before kitchen entrance. This will give you breathing room between lounge area and dining area. I'd put the tv on the buffet from the dining area until the right piece came along. Something like this arrangement is what you would see when walking down the entry hall. Imagine that fireplace as the tv.

The little things by the bufffet can go. Put the tv on a long, low-ish piece of furniture that can hold equipment, movies, etc. Eventually, turning that long wall from the entry into a storage/media center will help reduce that cluttered feeling. You can consider a set or collect pieces that play well with each other. Get a smaller, but useful dining table. One that expands would be ideal so that you have options if you need length.

So hard to please everyone. My husband asked me not to put the wooden table in the garage because there is no place to put it upstairs. He says the wooden table is an expensive one. why throw it in the garage. I bought a glass table for the lounge. what am I going to do now! He tells me to make two living parts and use both of the coffee tables :)) Goodness me ! :) Now I have two coffee tables. What am I going to do now ?

Losing the verticals will help a lot. They're practical but that's about it. I did see the sideboard in the model pictures but putting furniture in a space for looks versus practicality and function can sometimes be two different things. The width of your dining table top will also determine whether or not you can manage a sideboard. How wide is it?
