Hi, your home looks pretty good, you have done a lot on the interiors. Coming back to the question, yes, you can add a wallpaper behind the television, go for a textured wallpaper as it will create a compliment to your television. As you have decorated with wooden elements, you can go with a bookshelf on the wall. And, there is one more thing which will be a simple addition but will look perfect and that is an antique wall clock. An antique wall clock will make your wall look great without any fuss.

We used an amazing private cabinetmaker. He is a serious craftsman. We are in Brisbane, Qld. I'm happy to share his details.

@mazpt, yes of course. Here are a few more pictures showing how kitchen, living and dining, and outdoor deck and bbq area flow together. Oska kitchen is really neat in detailing; wood grain on the doors for example, are matched across as many doors as long as a 2.4m sheet allow. Floor turned out very nice too. Light natural colour, wide and long boards, laid length way all the way from front door to the back makes the space looks a bit bigger. Although it is still a floating floor, there are minimal floor movement that make squeak sound, most of the floor are feels solid. I hope that floor squeaking noise will settle over time.

i've attached my suggestion which doesn't knock down any walls or change the entry and only includes an 1800 wide sliding door on the side of the sunroom (with or without matching windows (cheaper than doors) across the front, big stackers are more expensive to buy and install, very expensive to add security doors or flyscreens and take up more floor space with bigger tracks) and i hope the sliding door on the side would be less obvious and more acceptable to the body corporate. i suggest you keep the living room as is, change the old kitchen to a bedroom and install a new kitchen/diner/laundry in the old bedroom without knocking down the wall into the sunroom although you may wish to remove the double doors if they take up too much space..if you keep the separate sunroom it can be called a third bedroom, if you ever decide to sell...the new plumbing is on the external wall, close to the existing plumbing and it could be convenient to keep a small sink in the new bedroom to use the old plumbing...should be relatively economical and achieve your main goal, hope you like!!
