What Is This Wall Symbol?

[Edwinlim 1]

Hello~~~

I just got a hdb office space. (still awaiting final confirmation)

It's a corner unit and this is the floor plan.

Any idea what the wall beside the main door means?

I went to see the unit it's only a door in front, and all walls, am thinking i wanna hack down the front walls and make windows.
