How about a coffee center. You Might squeeze in a small chair and coffee table too . If you like the idea there are all sorts of things you can use. Very on trend.

A couple of things you could do:

- Install some open shelving above the radiators for stylish storage.

-put art on the walls, an armchair and a light, so you don't have to walk far with your coffee to read your book

- remove one radiator and replace the other one with a modern tall model. use the empty wall to install a coffee station as previously suggested

Have you thought about adding a window seat as the window is quite big and low. It would be lovely to sit there when its raining or sunny and curl up with a book. Its definitely a feature you could leverage and make it into a cute little reading nook.

I agree with one of the comments above to remove both radiators and replace the one to the left with something more modern and longer. On the right hand wall I would add some pictures and a narrow bookshelf on the smaller wall. Or if you want to take it one step further is to get a Joiner build a window seat with some shelves on the right wall, because the wall is angled it might be tricky to get an off the market shelf to fit there.

Try https://desenio.co.uk - the prints are affordable and come in different sizes and even has the option to add frames.

If you are looking for original art work try https://www.riseart.com though its probably not best to put over a radiator!

If you don't like the view you can get wonderful window film to obscure the view and add beautiful dappled light patterns to the walls/floor. Its easy to install and can be removed when you want a change. Also I don't know if you have kids but if you have young kids I would put a table and chairs there for them to do homework whilst you are making dinner/lunch or whatever. If you don't have kids how about a little area for one of your hobbies? Here's the link window film

Check IKEA for small round table with pedestal.

I do think you need some plants to break up the warmth. Maybe others can advise what will work in low light but if not id use good quality artificial ones (it looks as if you've got sufficient distance from the radiator for it not to melt!). I agree a round rug would work. I've just added the Ikea chair but the John Lewis Hendricks one pictured below comes in a lot of fabrics. Again, ignore this particular light, but I might switch out that downlight for a pendant. You can add art over the left radiator or some African bowls could work. Maybe also a round brass and glass side table?
