I assume the furnishings in the second picture are from the previous owners?
Could you sketch up the space and show dimensions, with windows and doors shown too.
How many will you typically need to seat, will you have a tv, do you have any furniture yet?

Hi Najeebah thank you for your beautiful response.So in my living room we would like to have at least 6 seater sofa.I am not quite sure whether I should put tv as well in living room or notcause previous owner had their tv in dining room which is separate room.You are right that the photo i used before was previous owner photo thank you.I hope the second photo I uploaded will give you more idea.I apologise not having a clear dimension cause i am only be able to move in my house in coming Thursday which is 30 November thank you

If you use this room as a living room, and the dining room as a tv/family room, where will you dine? Do you want a dedicated dining room?
Do you have furniture? Two two-seaters and two armchairs could work well.
Not a problem, share exact dimensions when you can. The space is sizeable so you'd probably have some options.

are you going to repaint it at all ?

No chrish previous owner just repainted a week ago thank you

Hello,

If you’re planning to keep the wall (which would only be a matter of $50 and a few hours to repaint btw), then I’d look at introducing some lighter furniture to brighten up the place, and choose brighter, cool colours in your rug, cushions and art to complement the brown. Here are a few good options for furniture that we stock at www.northhem.com.au.

Repainting, especially the accent wall, would transform the space with relatively little money, time and effort. It is not necessary though, it's a good colour. I'm not crazy about it paired with the floor, but it could certainly be worse.
Green accents would work well.
Once again, we need to know, do you have any furniture that will be used here?

No I haven’t bought yet because I am not sure which colour will be perfect?

Hi, I'd paint over that wall with matching grey colour. Since the walls are pale grey, a nice bright blue rug will look good, darker grey settee and chairs with colourful blue cushions and throw rug, nice artwork with blue and coral colours or mirror above a small console table against that repainted wall. And charcoal colour blinds will also look good, if not dark grey curtains. Good luck.

Thank you very much Anjelah for your amazing idea, I appreciate that

l agree with painting the wall, it seems so lost there. A lighter color would be amazing!

There's a great deal that can be done, a great deal we can suggest, but a great deal will be shots in the dark.
Do you want an off-white sofa, light cushions, glass table, and pastel landscape art, or a forest green sofa with dramatic abstract art and a large pot-plant??
you need to consider your needs, and browse stores and pictures to get some idea of your preferences.
If you have pets or young children, look for hard wearing furniture.
Think about whether you prefer bold or neutral decor in general, bold accents or bold large furniture pieces, whether you want a bolder rug, table or seating, a lot of glass/metal/wood, whether you'll be moving again soon and need furniture versatile enough for most spaces, etc.
You're moving today right? Good luck, you'll probably be busy, so take your time, get back to us when you can

Thank you very much Najeebah. I am thinking of doing hallway with big round mirror with white table and some decor stuff.Is that be a great idea? cause as soon as we open our main door, the first thing we can see is that brown colour wall.Sorry about too many questions.

This is the photo

I assume by 'hallway' you mean the entire length to the wall opposite the door? sorry but that's rather strange, doesn't detract from the wall as you seem to intend, and leaves a wasted, unusable odd space and wall.
rather put a narrow console table (as a landing spot for keys and some ornaments) perpendicular to the feature wall, at the end closest to you as you enter the house. Beyond that, you can have seating

you are divide the space, and have a main seating area and a smaller nook for reading, studying/working, or a set of bookcases, a units for a drinks area, display storage of some sorts...

Perception, Bijou. I certainly don't see 'poo brown'

I'm surprised to admit I really like the brown. I usually don't like earthy neutrals of any shading but this one is ok, it certainly provided balance for the dark furniture the previous owners had. I love the idea of the side table at 90 degrees to the start of that wall to create a reading nook/dining space and redirect traffic. You could get something reasonable tall facing toward the glass doors to be storage/extension of the kitchen so there is a sense of connection. You could then put paint, wallpaper the back of that cupboard and put up the mirror and a little table for keys. Or even have matching bookshelves back to back and use the one facing the front door as a 'wet' room/shoe storage. Ikea sells so many great units that you can tailor the combination of size and shapes open and closed to get just the right look on each side.If you do this you have to screw the two units to each other so that stand straight and appear as one.

If you did use the nook as dinning space you could have all the serving/special stuff in that cupboard so you dont have to go far for setting the table and leave the kitchen cupboards for daily use stuff.

When I first moved into my big home from a super tiny apartment I just laid out what I had (plastic dinning set and all) as best I could and moved them around every few weeks till I got the combination of how to use the room right. Then I went and bought more/new furniture over the next 6 months.

If you don't like the colour then I would suggest painting it now. When I bought my house I made the mistake of keeping the apricot wall colour - not my first choice but I didn't actually hate it. The issue was that everything I bought had to coordinate with it, then when I eventually repainted I had to choose paint colour that went with the furnishings that went with the apricot and so on. In a way I am still living with the aftermath of it too many years later.

Thank you Maya seric and me me for beautiful ideas, you both are amazing
