Isometric Art to Blender Model

I have a set of 8 buildings, pretty geometric and simple ones in isometric style, and now need them translated into 3D in Blender. You. Don't need to do them to match the ref precisely, but they should not be simpler than what I attached, because what I have here are already simplified.

The deliverable must be a Blender file including all 8 buildings.

They don't need to have true to the world size. Camera ratio is 1:1.6 vertical, isometric angle (z rotation: 45 degrees)

Texture, I need the stroke line for the edges. The final feeling is like white crystal buildings

Light: yes, but white light only, I want to have the shadow a bit. However, no shadow on the ground floor, these will be floating buildings

Modification to based on the ref: I just need you to handle the bottom of each building a little so it feels like they are not attached to the ground, they should feel like floating, like I mentioned above

Blender version: any

Animation: each building rotates around its own axis 360 degrees in 2 secs, ease in and out apply.

Camera: each building stay fully in one camera view. 8 buildings -> 8 cameras
