Hi everyone, I'm planning to update my walk-in wardrobes, we moved into this home couple of years ago, the walk-in wardrobe just has a single shelf along 3 wallsides and rails below that. I want to remove these shelves and DIY a wardrobe with shelves and rails, I'm unable to locate the screws. I can see the caps closing the holes screws drilled in but I cannot see any screw heads. I could knock it down using hammer, but I don't want to cause any damage to the walls.
