Quick behind the scenes
The build was made in my spare time over a few days. I used a single clip from the movie as reference. The blocks used are concrete, iron blocks, polished blackstone and glass.
I started with the front of the tower. The back of it had to be made-up since we never get to see it. For the big sphere, I used the World Edit //hsphere command to make the glass, then manually added details. Once I was happy with the exterior, I manually made the inside. The important bit was the central elevator and the area inside the sphere. The rest of the tower contains a few made-up “maintenance floors”.
Side note: I cannot NOT point this out, but at one point in the movie the pups and Ryder go into a long hallway room to put their kits on. And I simply refuse to believe this hallway would fit anywhere in the tower, so obviously movie trickery was used.
For the surroundings, I built accurate roads and parks to “ground” the tower somewhere and add more to explore. The buildings are simple cubes (made with World Edit //faces) to not distract from the HQ tower. They are roughly accurate in size and color based on what we see in an aerial shot in the movie.
Lastly I added the pups Truck on the central road, which can be seen in the video below. Yes, I know it’s over-sized compared to everything, and would barely fit into the tower’s garage. Oh well.
