Loft is suitable as a temporary guest space or for kids only not a regular bedroom.

It’s for my son I just need a idea how to have the entrance and where to put the closet
It should be almost the same size as the other bedrooms there all around the same square footage

In a four bedroom house is it not possible for him to share with someone else and have a proper room? When I said suitable for kids I met for sleepovers etc not all the time. How will you enclose it? Can you? Door to the bedroom bottom of pic makes it tricky

Where is the person that designed the house on this?

It’s a floor plan by lennar unfortunately when we purchased they didn’t offer the turn the loft into a bedroom option they do now but I have yet to see the new floor plan

This is the best Iv come up with
I’m still trying to work it out from my calculations the room will be around 10x11 which is the same as bedroom four With a door on a angle

Maybe something like this?

eta: That is a reach-in closet. Also, see if the space can fit a minimum 42-inch wide hallway(s). And, it would be best if the door opens against the wall. . .so, you will probably want to move it over towards the corner if this set-up works.

2nd eta: I just realized that you mentioned that the door cannot face another door. In this case, move it to the wall facing the staircase.

Tendrac the hall way with this set up will be 45 in
I think this may work
