At the moment all your stuff is concentrated at one side of he room making it cluttered and bare at the same time. Pictures need to go at eye height, so maybe get a simple shelf built above the sofa at eye height for some knick knacks. Somehow your pictures seem very high up on the wall. You could cluster them together above the sofa maybe? You can still have your mantel but with maybe a better-selected range of bits on it. Agree that some shelving might be good in the alcoves but not above the line of the top of those pictures. I would have gone for a much darker colour for the walls (like navy blue) because the sofa would have blended in a bit more and it would look luxurious against the dark background. Plus dark colours give your stuff an instant quality upgrade. (I always say it makes my sh*t look like stuff) Sorry that's unhelpful as you've obviously made those decisions!!

Maybe an L shaped, with no back on one part of the L, this backless part in front of the windows so the view/light isn't blocked. Its hard to tell if you can fit a 2 seater in as opening to RT would be blocked also... so maybe 2 neater comfy chairs ...you might fit a love seat in. Sometimes a skinny console table with a lamp etc is nice to have against the back of the sofa as it can help define the 2 different areas.. just my thoughts. I think that's concrete floor? you can draw your dimensions before you buy to see if they'll work..

Hi im looking to get a new sofa for my living room . I currently have an L shape but and not happy with it . There is only one really wall which I think it can be placed and its infront of my window which I think is blocking light ? And is against curtains . I'm thinking of also get roman curtain blinds in a pelmet box to avoid that ? I'm looking for any advice or inspiration I don't mind changing the style decor of the room ? Also I need storage for toddler toys so need to redesign and layout Photos in comments

It’s a beautiful couch and looks very comfy. Maybe anchor it with a large mat to define the space & try & wall Mount the TV. Make it feel a cosy space. Good luck https://www.houzz.ie/hznb/photos/rosefield-model-farm-road-cork-phvw-vp~141949230
