Hello, I'm trying to find a YouTube video about conceptual/Envisioned buildings. It’s a long video consisting of screenshots of the buildings and a male voice over. I believe the video starts with real buildings such as the Burj Khalifa before going on to conceptual buildings like the X-Seed 4000 and the Volkshalle.

I tried many different search terms but I just can’t find it. I don’t remember the title or channel, last time I saw it was 1-2 years ago.
