Open wooden shelving is rather common. Experimentation arises when the wood used is different. In this case, for instance, there is rectangular, dark wood shelving throughout. When you design such shelves, make sure the wood is strong enough for you to place heavy utensils. Another designing strategy is to mount wooden planks opposite each other on the walls and place wooden strips between them for the dishes.
There are plenty of open kitchen shelves designs using metal. Metal is used for sturdiness and stability. You can use heavy black metal, with a staircase-design, placed over the counter top or kitchen table. Or, use an alloy to mount shelves with screws on the wall. The shelves should have criss-cross patterns for the convenience of hanging casseroles.
This could be a DIY project for open kitchen shelves. Use pantry-shelving where you need to store a lot of items, and when you need to understand how to organize open kitchen shelves. The one mounted on the wall is almost a cabinet design, minus the doors. The other design is a huge open shelf, placed on a table. Place items carefully, since the shelf is open on both sides.
