Kitchen wall cabinets on drywall

Oh, and definitely ask the kitchen supplier about the installation height of the rails, there is no standard!

My architect said that all drywall panels are double. First something with wood, then the drywall panel.

The question is also how your house provider has their wall structure. We also have drywall.. but only as a top layer, behind it are wooden walls. We can attach everything up to about 80kg to the wall without anchors, simply with wood screws.

The question is also how your house builder has his wall structure. We also have drywall.. but only as a top layer, behind it are wooden walls. We can attach everything up to about 80kg easily to the wall without plugs using wood screws.

It's the same with us. First wood, then drywall. I even asked the architect again.

then staple those things on...

What is "something with wood"? If it is OSB, no problem. But you should perhaps know a bit more about it in detail.
