We need an actual to scale floor plan showing all windows, doorways , where those lead every measurement clearly marked . Do it on graph paper to make it easier then post here in jpeg format in a comment. How many seats do you need always . How big is the TV show the kitchen on the drawing. What you posted is usless if you really want help. Do you have furniture now that needs to be considered ?Is there a dining room somehwere? After you post the plan thre will be questions back and forth so try to check back for more help.

If you used a ruler, a bold pencil and 1/4 to a foot with a ruler............you can do a lot better with the sketch you posted.Does rvry dimension matter? Yes it does. To get help. post a better ^^^

drawing, Every solid wall, every opening has a dimension. Exactly the location of the island, It all MATTERS .

It is like a 3/4, 1/4 vaulted ceiling. How about this idea? Wrap thhe kitchen cabinets around the perimeter. Place the family room furniture facing the other end of the room where you install the t v.

Because there is an off side peak, install the t v entertainment piece with the t v under the larger ceiling. Don't try to center it with the peak.

"Elvis" left for spring break........nothing valuable in advice comes without a decent drawing and accurate dimensions for everything
