It’s not easy to effectively use the standard builders shelf layout.
Typically a standard builders shelf spacing is a 400mm vertical spacing between shelves in a pantry, linen press, or for clothes storage.
The top shelf will be around 1600mm from the floor.
The trouble is that you can’t find things at the back and things are piled too high for easy access.
The Half Shelf Solution
To improve the situation I normally install half shelves.
These are typically 200mm from the supporting shelf and half the depth of the cupboard.
Doesn’t seem much but its surprising the difference it makes.
Don’t believe me just install one, and you will soon want more.
