I think you could get the telly put over the fireplace. Might need a mantle to deflect radiant heat, not sure. But on the cables and power, I imagine they can get that sorted. Im guessing there is a wall behind you when you took the photos. I agree that a low corner modular sofa would look great. Just don't get it so long that it is up against the fireplace wall. Placed into that corner of end and piano walls . Then pop your cute chair where the sofa is now. Large ( big enough for the sofa front legs sit on it, I'm guessing 2x3m or even 3x4m) patterned rug to define the area. Can you move the piano to another room or against the computer area wall? Can you make the small windowed room the homework hub? Imagine a long bench against the window ( Ikea do a good cheap range that you make to fit your space). Ensuring the computers are in line of sight from the kitchen(?). Pull out the table to give it more space around it. Or flip it to run the other direction. Hard to tell from the pics the dimensions. Paint a lighter shade as mentioned before. A sketch of your floorplan would be really helpful :)

paint the end door a striking colour, horizontal stripes on the ceiling, and 3 large pendant lights. not sure how adventurous you are, but you could consider painting different colour "zones"- 3 different colurs as you walk down the passage.....possibly even 3 short carpet runners. i love the idea of wainscoting-but you will lose precious centimetres. You can get paintable wallpaper wainscotting.

My advice would be to get rid of the blind as you won't use it once you have the curtains - perhaps you could use it elsewhere or have it as a spare. You would probably find that without the blind you will use the access more often. I would do full height and full width drapes - an inverted pleat is attractive with heavier fabrics but if you have the light fabric on the top keep it simple. How about putting your sheer lighter drape on the side closest to the bedroom and have the blackout lining behind. This gives softer look in your room. You would probably find that without the blind you will use the access more often. If there is a lot of sun take care with the pure linen cotton and natural fibres as they will rot with light and sun. There are many synthetic linen look alternatives that are less expensive, last longer and have the same look. I feel your room could do with some texture - you could possibly have a subtle self coloured stripe in the drape - or go plain and have the interest in your bedding. If you want to go soft grey drapes I would go for a darker charcocal or midnight blue/ teal colour on your walls which would look awesome with a soft grey linen look curtain and natural bedding. You could introduce soft mustard, peachy pinks and soft apple green linens in your bed cushions.

Rachael, you’re very welcome! It was fun to draw up. As far as layering photos, I wasn’t suggesting you cover one photo with another, (what is the point of having beautiful photos and memories then! Lol) rather, overlap the edges of the frames (both are quite wide from your photos) so that they are connected without obscuring the images within. Hope that makes sense! What a difference just painting that back wall makes! It really opens up the room now. I think the few bricks around your fireplace now is a very charming feature. It keeps the charm of the original while bringing the rest of the room into a fresh new era! Well done! I would suggest running a long extension chord for your tv for now while you try out a new layout for the space if there are no powerpoints on the far wall, just to be sure you like the arrangement. Can’t wait to see updated images of your new space!
