Here my explanation on how to do

1. Step 1:

   Import a reference image as background.
   Place it in the front view and center it over the Z axis.
   Scale the image to fit the real height of the building.
   Trace a ControlPoint Curve over the externa profile
   

   

2. Step 2:

   Using the _Revolve tool create the main surface of the building.
   

   

3. Step 3:

   Using the _UVCurve tools create the UV rectangle, it's like to unroll the surface.
   Inside the rectangle create a grid of lines, in this case along the diagonal.
   

   

4. Step 4:

   Let's use the Sweep1R with a square section to create a 3DGrid from the grid lines.
   

   

5. Step 5:

6. Step 6:

   Over the 3DGrid create a simple rectangular Plane.
   Split this plane with the grid lines and change color to the resulting tiles.
   In fact this are the panels over the structure.
   

   

7. Step 7:

   Now the magic parts: using FlowSrf deform, bend, the flat 3D model over the main surface to get a much complex shape following the main surface.
   

   

8. Step 8:
