Build a plant wall for the hallway yourself

Hello everyone!

Somewhere here in the forum, I once saw a beautiful wall (interior!) full of plants!

That would appeal to me for our hallway.
There is a wall area (2.5x2.5m) there that would be perfect for something like that!
Above all, the plant wall would definitely absorb a lot of sound! Which would be beneficial for us.

Can someone explain to me how something like that is constructed?
I am envisioning a wooden structure as a trellis?! or as a shelf for pots?! And below, a large "raised bed" (made of wood?!) as a "base," where several liters of water are stored including pumps and controls to realize automatic irrigation.

A few detailed pictures, explanations, or suggestions would be great! Especially regarding the selection of the plants.

Those were planting bags. I can't scroll quickly because of slow internet, but have a look in the [Bad-Thread], it was a bathroom picture after all.

ypg probably means this thread. I also have very positive memories of the planting pockets there.

I meant this one

But they are the same pictures
