I want to recreate the animated line art on the buildings, But I’m not sure how to go about doing it.
Any help is appreciated.
The example animation is pretty fast. It’s not quite clear exactly which parts of this you are trying to replicate.
blender’s GreasePencil is an obvious choice for line-art type things.
If you’re not into greasePencil, then perhaps just recreate the parts you want to animate as planes, rectangles, and various rectangular-solids (start with cube…) and animate them in 3D. The AnimAll addon or Shapekeys can help if you want these simple shapes to morph during the animation.
Welcome

for better reference… (mainly the first 12 seconds ) of and maybe at 0.25 speed :
…and as @shannonz said any GreasePencil tutorial (this is a bit older for 2.93)

You can use grease pencil.
