Hi Bella, The shape of the TV wall is long and reasonably short in height (in comparison to the voluminous ceiling area. I have a couple of suggestions to help balance this space out and not make the TV look so lonely all on its own.

Firstly add built in wall length cabinetry 55mm heigh the entire length of the wall, maybe adding some tall book shelves on the right hand corner. Then on the left hand side you can style the top of the cabinet with accessories and smaller artworks of varying heights to draw your eye away from the length of the wall.

When I first looked , I thought there were blue tones in the room , and I gave up haha . But looking again , I think the main tones are grey and charcoal ? I hope so . . . . .

So paint ( or wallpaper ) that whole wall . Personally , I'd go burnt orange in a paint ( which , of course , isn't all that orange ) , or something in a bright or rich red base , if wallpapered -- imagine a rich red with thin beige and mid gold vertical lines if you want a classic look for example .

Then matching modern standard lamps -- 1 each end . Wall mount the TV , or go for a bigger tele ( yes , I know , a lot of people don't want that as the feature , but it is a big wall ! ) BUT add 1 or 2 prints or paintings on that wall too -- again , my personal choice would be one bigger than your TV , with bright red base tones ( against a rich red wallpaper ) , and splashes of orange and yellow and beige and blue and -- you get the idea ! An abstract landscape or racehorse or torso or whatever floats your boat -- I don't like the swirly or straight line types of art , but obviously some people do .

Still look sparse ? A large colourful glazed pot or two , with suitable indoor leafy plants/cactii/similar . A big shaggy rug in a warm red or orange or orangy red .

Adds life , colour , warmth -- all around a common theme . And thats why I shuddered at the initial thought of blue -- 7 different blue tones will never look as warm , and red and orange never looks as good against a blue , so you are stuck with the colder look IMO .

Hello. Feel free to post a rough floor plan of the space for help with layout.

In regards to the wall with keeping your television there, if your budget is decent, a tv wall would be great. If your budget is lower, a new entertainment unit would be first in line, the current one is too small, measure the wall and pick one roughly a third of that length to balance it out. A rug in front of the sofa will zone that space nicely, pick something with some pattern or contrast to add interest. You will find by refining the space around the sofa will remove the need to cover the wall. Your colour scheme is cool not warm, so ditch the cream soft furnishings and go for grey/taupes to make it easy. Good luck!
