How to renovate wardrobe and shelving?

[emmad25]

I am planning a makeover and upgrade of my walk-in-robe. As part of the project I’ll be adding some cool wallpaper on the wall you see directly in front in the picture. 

The shelving on the side walls have cleats holding them up. I’m wondering if there are any alternatives to using cleats so that they don’t impact the look of the wallpaper. 

Ideally the shelves would look like they are floating. Although I’m not sure if that would offer enough support. 

The shelves are 1168 x 460 and behind the plasterboard is brick. 

Thanks
