#1 Corner Units

OK So there's this awful corner unit on the wall.

It needs to go away for ever and also before the plasterer comes to skim the ceiling. How the heck do I get it off the wall!? all I can see are these two screw bits in the side cupboards...

 


BUT! There's nothing in the middle cupboard!

Is that right? If I unscrew the left and right thingies will the whole thing fall off? Do I just go incredible hulk and rip it off the wall?! Help Me, Dad!!
