The second room is what you need. Do you have hobbies? Do you need a library? Office? Art studio? Craft room? Do you need a second bedroom for visits from kids or inlaws?

another idea, the extra room can be the TV room, which makes it much easier to arrange the main room. many times, the main room is arranged around the tv, and it can be awkward.

This layout should work for the room

I would keep the mirrored wall but select a not too heavy canvas to mount on the face of the mirror to break up the wall. You can use the 3M Command Hooks to hang the art.

What is the green line bisecting the bedroom?

Thank you for asking and I should’ve clarified - I’m borrowing another unit’s layout. Theirs is technically a 1br, but mine is split into two bedrooms, which is what that green line is representing

The 2nd room could be an office/guest room. I like that idea.

Beverley, I do like how you’ve laid out the furniture. I wasn’t sure about the mirror and how to furnish around it
