There are tons of papers available that would go with your midcentury home. Many people tire of a paper quicker than they are ready to redecorate and they can also look dated in a couple of years. Metallic papers were big im midcentury...perhaps a metallic silver paper? Are you also considering paint? You can get it in so many textures and a blue wall to match the blue in your loveseat would be lovely with some midcentury art and sculpture, or photographs on it. A mirrored wall with or without art or sculpture would also work with midcentury. These treatments are easier to adapt should you wish to change the look slightly from time to time. I would suggest replacing your stairrail with chrome or acrylic if that is in the budget...see how well the loveseat frame looks with the fabric? I hope you will post the "after" photos for us to see. Above all, enjoy the process!

It's way too cluttered in there. The first thing I would do is get rid of that small 1/2 wall with the 2 seats, I can;t see how it would be useful at all. If there is a counter in front of that wall get rid of that also then at least the space will open up between the kitchen and I guess thats a little eating area in front of the sliding doors I then would rearrange the living room. Right now it looks like you have a couch that is almost acting like a wall between the living room and eating area. That couch is breaking up the flow pattern and also making the place feel cramped. I would move the TV where that wall that separates the kitchen is (The L shaped stagger wall) Move the large couch where the TV is now and the smaller one opposite where it is now. So now when someone walks in they walk into an open area and it has a nice flow to all three areas. Also get rid of that Pallet table, go with something with a glass top, so while it is functional it's not overwhelming like that way too large pallet table

Ozbern: we had a similar dilemma, lovely backyard and then they started tearing down bungalows and building four story townhouses all around us. I built a single depth pergola along the back property line, the beauty of this is not only the privacy, but it brings the scale of the yard down to make it feel more intimate when we are outside. We also added a 10' x 10' (little over three meters) pergola right up against the house where we had a wall of windows. Will try to find that photo too. We have coral vine now growing in it. Dies in winter, comes back in spring. You can always do more contemporary details if this is too casual.

I assume the windows abut in the corner? This would make it tricky to have romans as they would probably clash when both drawn up. Curtains drawing away from the corners add softness to a dining area, but make them floor length as short curtains look a bit half mast. It is also a good idea to have them wider than the windows to allow more light in when opened and fitted from above the window to elongate the window.
