Can't tell exactly from the pics but could the two sofas be brought closer together positioned facing each other with a coffee table inbetween and the tv then put underneath the stairs? Would there be enough room to walk from the door through to the back room? It would make a nice seating area on the rug which you could change to a bold geometric monotone one if budget allows. Then some bold complimentary cushions also in monotones for the sofas and I agree with the pops of orange. I don't think it would matter if the sofas went right up to the present tv wall. At the moment everything seems to be pushed to the furthest extremes. Then you could have a table/desk or the pine cabinet under the window. I would paint it with Annie Sloan chalk paint which is very easy because you do not have to sand or undercoat and you can finish it with just a wipe of her wax which gives a nice finish. Paris grey is a good neutral colour. You could paint the wall with it also. (Sorry but I don't like the wallpaper sample. It looks too bedroomy to me.) If you are ever in a position to do so I would have the chimney breast removed because it has no purpose, takes up valuable space and is off centre as well. The wall facing the stairs would look nice a medium grey and needs a wow factor with a collection of some colourful or big art. I don't think the mirror works there. It just accentuates how the chimney breast is off centre. I would put pictures above the whole seating area on both the chimney breast and the wall to the right of it to centre the whole look. Not sure what you curtains are or whether they need to stay. Something to consider..... :)

A flickering flame surrounded by ancient carved stone - Antique stone fireplaces add both character and a sense of place to any room, the knocks and bumps of the decades nay centuries, connecting hearth to home. Even with the advent of central and underfloor heating we crave that focal gathering point that a fireplace provides - a room without a fireplace? Nowhere to hang the picture, mirror or tapestry, no were to put your cards and certainly no place to hang your Christmas stocking!

I eat every meal at a table, not in front of the TV. Right now the only table happens to be in the dining room but it's been in my lounge in past homes (and I've lived alone in London so some lounges have been minuscule and been the ONLY room). I don't usually eat alone but if I am I may occasionally flip through a magazine, but I have always eaten at some form of a table and there is never a TV on. I wouldn't use the term vulgar but balancing a plate while watching tv, especially while eating with others isn't how I'd like to enjoy my meals, my family/friends or my TV. Simple pleasures.

I use a program called pipette, https://www.sttmedia.com/pipette-download and you can find the colour composition of any image ie rgb, cmy etc, its also the true colour of the image and not how your screen presents it. Obviously with a photo this won't be the actual colour and also with a photo the colour changes in different parts of the photo. You could then download colour charts and use pipette to see which colour is closest to the photo results or do a search on line for the #hex colour, you can try encycolorpedia.com and that gives you a list of paints that are close to it.
