I'd go with option B as being more liveable - but you are going to get annoyed every time you have to climb on the bed to reach the blind cord, and changing the sheets is going to be a pain with the bed against the wall. But you'll do those much less often than you will sit at your desk, so I'd prioritise that space.

Option B would be my preference. Nice planning, what ap did you use to draw it?

B makes way more sense on so many levels, losing bed drawer access is minor compared to how cramped it would be getting to bed in A + weird wasted corner. Just see how you'd feel with the desk being so close to the bedhead in B though, in terms of height difference and how likely you might bang your head against it (but also whether maybe you could use it as a bedside table)

I reckon option b is the winner too. I nearly did the same except I do a lot of zoom stuff and hate fake backgrounds and hate the idea of people seeing my messy bed! For now I have poked the desk into my living room.

Not much room for a reading chair either way. B is a bit less cluttered, but very much a one person layout. Don’t know if I could sleep facing a mirror.

Assuming the windows are on the wall to the left of the door on entry, I would give some thought to flipping the bed through 180 degrees as per revised option B so it faces away from the window. Depending on how much you like lying in bed staring out the window or at the mirror robes. Then the Alex drawer can be put next to the head end and be your bedside table but will still be accessible to the desk. It will help screen your bed from the doorway too. Moving the bed from being jammed up against a wall/window at the head/foot end could make quite a difference to usability. It'll simplify changing sheets quite a lot if you can easily access both head and foot of the bed. Even if the access is only 30 cm or so. Opens up access to the full width of the mirror robe too.

That carpet has seen better days!
