I've got an office with minimal true wall space, lots of consecutive windows, and built ins.

There is no ceiling light so it is a blank canvas ceiling wise.

The desk is currently built in (see pictures), but I'd like to add another desk so that the cabinet/desk is to my back and I face the windows when working.

What on earth do I do with these windows, and the lack of ceiling light could lend itself to wallpaper potentially...

EAST WALL ^^

NORTH WALL ^^ (i'd like to paint this the same color as I end up painting the walls)

SOUTH WALL ^^

and then the west wall is a built in bookshelf and 2 french doors and a small wall (pictured in north wall pic)
