With the building as a Nanite mesh, you can try enabling Nanite in Raytracing with r.raytracing.nanite.mode 1 and see if that makes them appear in your reflections.

3

What version of the engine are you in?

5

r.raytracing.nanite.mode 1 worked , but is there some performance drawback to this?

6

5.6

7

Yes

8

how much? is it the instance traversal or the amount of triangles in a bounding box? the balance, right? : )

Raytracing will hit different, likely more high-resolution geometry. You can run a GPU Profile between the two modes to see how much it affects you.
