Could you draw out the room with measurements, windows and doorways and post it. Will this room be used for TV watching? If so, is there a wall that it has to go on for the wiring? And yes, that shelving needs to go!

The sectional looks better than others. I advise you to make it like this. Moreover, for your room, you can take vintage furniture. It will make your room richer. When I moved to my new house a year ago, I noticed that something was not reaching the living room. After a time, I decided to change the furniture and I opted for a vintage one. After changes, the living room looks better, more colorful and this type of furniture gives unusual magic to the room. If you want to find more about vintage, look on osvaldoantiguidades, from there we bought our furniture.

The floor plan helps! I'd place the tv above your console table on the recessed wall to the right of the fireplace. Group your furniture in the largest part of the room on the right side, with a sofa floating in the room and facing the tv/fireplace and another sofa with it's back to the sliders with room behind it. Your chair and ottoman would go to the left of the fireplace, along with your shelves that are currently there. That gives you a large rectangular area for the main seating with the focus on both the tv and fireplace.

You'll get the best help if you can please provide us with a hand drawn floor plan and measurements. Please label where the living room and dining room is on the floor plan. A couch and chairs are easier to decorate than a sectional. Bland is not bad - it gives you a lot of options - it doesn't limit you.
