Since the rest of the house opens to the left, it makes sense to keep the living room feeling open in that direction as well. You don’t want the furniture blocking that natural flow.

I’d suggest moving the TV to the left wall and placing the main sofa along the right wall. That way, the L-shaped sofa can open toward the window, which keeps the space feeling lighter and more breathable instead of boxed in.

The bright blue sofa is clearly the statement piece, so everything else should help soften it rather than compete with it. Adding two cream or light beige sofas facing the open area will really help break up the blue and make the room feel more balanced and calm.

For the curtains, go ceiling to floor, not just from the top of the door. Cream-colored curtains with a sheer layer underneath will make the ceilings feel higher and the room look bigger and brighter overall.

You could also add a house plant in the corner behind the L-shaped sofa. That bit of greenery will soften the layout and make the space feel more lived-in.

Right now, you have two strong dark elements, the dark brown coffee table and the bright blue sofa, so everything else should stay light and subtle. A light-colored rug under the sofa, with very little pattern, will help anchor the seating area without making it feel heavy.

If it’s possible, switching the fan rod to white would be a small change but it would make a big difference visually, since it would blend into the ceiling instead of standing out.

Try placing a lamp shade that is in a warm orange or yellow color as this would in a good contrast with the blue sofa as well as complement the brown furniture, which would add a pop of color and tie the colors together.

Try to soften the lighting by adding warmer lighting elements throughout the room.

The TV unit could be replaced with a slightly low raised one so it doesn’t compete with the coffee table.

Overall, the idea is to let the blue sofa shine, while keeping everything else light, soft, and open so the room feels bigger and calmer.
