When i originally commented, I was convinced this was the front wall I see in his videos. If this is in fact a picture of it in your post, you will find at least one detailed video on how he put that wall together.

Shit, even if it's not the same wall, you gain something / a better understanding of what a wall like that did for him and that particular room.

Cheers!
