It is a wallpaper, but the website isn't active anymore. I didn't have much luck with the exact one, but this is similar. https://www.etsy.com/listing/971072425/3d-abstract-traingles-wallpaper-mural?gpla=1&gao=1&&utm_source=bing&utm_medium=cpc&utm_campaign=shopping_us_c-home_and_living-home_decor-wall_decor-wallpaper&utm_custom1=k_744eddc564711c38c290bd9c6594d2b6_k&utm_content=bing_319895457_1302921427446871_81432615571304_pla-4585032209645604:pla-4585032209645604_c__971072425&utm_custom2=319895457&msclkid=744eddc564711c38c290bd9c6594d2b6

Searched for 3d wall murals and that turned up some more options. https://www.etsy.com/listing/787867300/custom-wallpaper-home-decoration?ref=related-1&pro=1

I would guess this is framed/sheetrocked to the architect's/artist's specifications. This is a custom job; you'd have to look at it like an art installation.

If you're just looking for 3D wall panels, here's a company that has a variety of styles and patterns: https://www.textures3dpanels.com/?keyword=headboard%20wall%20panels&gclid=CjwKCAjwgOGCBhAlEiwA7FUXkgRG285MRytzfHSftKwmv06rQpoB0H8dew2tcp5eh5EEo-m_X3uRERoC4tIQAvD_BwE

Kayozz, thank you. I was certain that was not wall paper, but seeing the pages you shared, I am not so sure anymore!

Sabrina, that’s what I was originally thinking as well.. if that is the case, sadly it would not work for the space we are thinking (which will have a pocket door..)

One way to tell that it is wallpaper versus a build out is the baseboard. It runs straight across. If the wall was built out, the baseboard would follow the lines.

Thank you, kayozzy! That’s useful to know

Man, that looks awesome! I have never seen such a tremendous 3D wall. Honestly, that is incredible. I would love to have such a wall in my living room or maybe in the dining room. Actually, I want to renovate my dining room, kitchen, and living room so that I might get such a 3D wall. However, I would also like to keep the pet portraits from the living room and dining room. If you guys want to get some fantastic pictures of your pets, you could contact the guys from https://impersonateme.com/collections/animal-wall-art. They are doing a good job.
