How about a paint or preferably a grass cloth wall covering in a color similar to this, and replacing wood floor with oak stained medium walnut with a 1"-2" banding "picture framing" in dark walnut inset 12" from wall
Nice window treatment and wall color. Textural linen drapes and grasscloth on the walls.
Built-in shelving, window treatment ideas
Idea for built-ins flanking the LR fireplace
These cabinet fronts are reminiscent of what is existing but painted white.. they might look pretty darn good painted white.
