Are 'Vp Buildings' still a thing in ttr? and how did they originally work??

https://www.youtube.com/watch?v=2SUwlAGAmbY&t=22s (here is the video I'm referencing on how I learned about it.

I've been playing Toontown Rewritten since it came out at around 6 years old when my mom made me an account so I could play with my older brother and I had never heard about a 'Vp Building' until I saw that video appear on my front page.

I was just wondering if it is still possible in ttr and if it was ever possible to get the other bosses as a building too. (essentially, I think the building shows as a 1 story building and it has the first round of the vp in just one floor)
