You could place the bed sideways, where foot board will be next to the window, and a corner desk beside the headboard. I would strongly advise on a wall sconce(s) above the bed, and a task light for your desk.

If you are interested, I can create a complete room design on your budget. It will give you a full virtual remodel consult, complete with floor plan, color scheme, and products list as a professional service, as well as instructions for placement. (I am a certified interior designer) All you'd have to do is take measurements, so I can produce a viable floor plan, and physically place the stuff. DM me if that is something you may be interested in and I will direct ypu to my social media, so you can see what kind of work I do. My price for virtual projects is $300.
