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 :)

Thanks for all the suggestions. It's taken a bit of time but I have collected a few pieces to make the space look better. I decided on a table lamp and have grouped some photos behind it. I'm really happy with the result. a couple of new cushion covers for some more colour which I love. I also have a clock for the far right wall and a picture for behind the couch. i don't love the picture but it will do until I can find something I really like (and have the funds for). thanks for all the great suggestions.

Thank you for your suggestions. I plan to visit Chadstone one day for a visit to West Elm and Pottery Barn. I hadn't thought of Laura Ashley, so may look there, too. As for Wayfair, I prefer to see the lamps in person. I had high hopes for some lamps I saw on a website, but when I saw them in store I found them to be poorly made. Fig Ivy Cottage--following your suggestion, I had a look at Schots website and found a number of prospects. Thanks, I hadn't every looked at their website. I'll try to fit in a visit and see what comes of that.

Gorgeous colour scheme, look for black planters, a textured light coloured rug would look beautiful, linen throw, and some fun cushions picking up your colours would look stunning .
