I can see you like minimal furniture and clean lines so I will remember this when I comment. You are getting a new bigger tv, which I think would help balance the wall/tv ratio which is great, would you consider a long, low entertainment unit? Regardless that your tv is mounted. Have a look at this website; www.sydneyside.net.au Also, I do like the dark rug (recently bought a dark charcoal one myself) but it looks too small for the space. The next size would have worked better. Sizing is everything with rugs.

Looks good. Before I read through discussion, I had these thoughts. You could look at painting on the front of the wall only, not in the porch/entranceway area underneath, double strength of main colour. So you could as an option get a test pot of Dulux double Self Destruct or even triple. I would not use Monument, or similar to the roof color as it will disappear into the roof. I also think the front fence would look better painted a stronger colour from your existing but as it seems it has just been painted perhaps you could do that, when and if you liked, to cut down expense. On the Dulux website they also give you colours that look good with Self Destruct. (Picture below). Another option is look towards going bold like a strong blue or blue green. Something like in the picture. That's my feature wall, Resene Billabong. ...or a dirty purple or a blood red. It's starting to get really personal of what your tastes are. Perhaps you could Half or Quarter the main house colour in the entranceway so it still flows but gives you more light. Exciting stuff!

brick wall so no option for cavity sliders gas heaters are already in that middle wall as marked, old heaters i think i need to service them as not sure when its serviced last also has two split aircons on both rooms on the far end no weather seals on entry doors, i can feel cold air is coming under some doors, where can i get the seals or is there someone who can come nd check all doors/windows and seal them tin flat room with not much space in between. I think there is insulation in the middle if not its very hard to do anything without opening up the roof sheets. We have double roller blinds on one side. No curtains on patio door(kitchen).

Depends a little bit on the style of your house , but my first reaction is the same as bigreader -- no , and almost certainly no , no , no , no , not 4 rooms in one house . Some of the schists look alright , the 80's style might suit an 80's or even 50's minimalist American house . There are some fairly cool 'wavy' panels that are available these days ; even some feature walls that look like timber ends sticking out of a wall ; wallpaper works in some places ; but one wall of brighter paint is the most obvious 'feature wall' . Faux Stone , or that ship-lap timber , or diagonal timber are about as exciting as yellowy beige or mission brown .
