Hello
I loved that layout too and with a research discovered an app called black blocks.it creates empty folder icons(as many as you want).After creating them arrlittleange them before the normal icons and you have achieved what you wanted.
To get 5 icons in a row you can use quick tweaks by schturman.the wallpapers were provided by a kind user up above.
Be sure to remove icon shadows to not get black shadows over the wallpaper.
(use ambiance settings to create the wallpaper)
Hope i helped.
