The sash bars make it look more traditional. You don't have to style it like that though. If you create a black shelf with two big screen glass doors it looks completely different. You could also put the TV itself inside the fireplace. For me that's not an option because I don't like looking down on the TV. I prefere to lean back and look up. But if you're someone who preferes their TV close to the ground then consider it. And just think about how the fireplace channel will looks inside an actual fire place :)

Can you do anything with shelves on the blank or door walls? Are the cupboards a built in wardrobe, or is there capacity to put your chest of drawers contents either on shelves or in baskets in the cupboards? Is there room for a freestanding hanging rack of some sort if there is no wardrobe hanging option? Pics would help!

I agree with jmm1837 about the lounge, but I think it might be the hide throw cushions that makes visualisation harder - maybe think about saving those for a different look. Perhaps have the room an ecclectic mix rather than one specific style. Think about light sandy beige (not cream) walls, lighter timber floors, the odd piece of furniture in a lighter timber or that's been limed or even glass topped to keep the room feeling open. Using furniture that has been lime washed and distressed can also work. Because your cowhide sofa's are statement pieces, think about bringing in the beach feel with colour rather than specific objects. You could try using really large abstract art pieces (eg. if it's over a buffet then it have it the width of the buffet, if it's a bare wall then try to use up all the space either using a singe canvas or a triptych) that use beach colours you want to incorporate . Echo the colours of that artwork and even a bit brighter or paler but in the same colour family in your accessories and soft furnishings. You could also incorporate lamps that are glass/beaten silver/rope bases and light coloured lampshades. You might also want to think about a really large fluffy area rug in a light neutral/sandy colour under a glass low coffee table for the middle of your sofa area. On that table you could then feature beachy accessories such as a bowl of shells, a piece of driftwood or low piece of art such as metal fish or a ceramic starfish etc. just keep it simple so it doesn't look kitsch Burlap is great but it can be hard on your hands and sewing machine if your making curtains yourself and doesn't block out light unless your using backing - unbleached calico that is rubber backed is an alternative for privacy if you decide that dealing with miles of prickly burlap is not what you want to do - keep the burlap/calico to give you more privacy as pull across curtains using them to dress the walls on the sides of your windows (makes them look bigger) using a second curtain rod, and use your sheer curtains to give you a beaufiful breezy feel on a more discrete rod (you can even use a curtain wire kit if you're not going to draw the sheers aside). To keep your casual beachy feel think about using large curtain rings on a rod for easy sliding or big eyelets on a chunky rod with distinctive finials Good luck with your project!

Been away just saw this I agree with others remove round coffee table replace with a not too large rectangular glass. Wall hang tv, (my choice above fireplace) remove tv console (u could use a low shelf of book case for DVD etc. ) replace with chest. Another option if it fits: Relocate left bookcase to where black recliner is & put recliner in that corner with floor lamp maybe behind it. The square box coffee tbl also looks out of place. Also Could one of door openings be filled in if there is an alternative access out of the room to the right of fire place. Love the fire place & floors.
