I need to know the meaurements of the space and your table but I don’t see room for a buffet in those pictures or for that matter a rug The easiest is to meaure your table then add 3’ to all sides that tells you how big the rug should be . IMO the first thing to do is find quitea large piece of art you love and hang it on either of those large walls centered on the table and a nice centerpiece for the table . Also if you can a picture of the LR will give us a bit better idea of style.

Thanks Patricia! I haven't bought any furniture in the living room yet.I need a window treatment and sofa and etc.My wall color is Big Chill from Sherwin-Williams.
