How to put an object on top of another growing object?

I have a group of parent/children gameobjects growing altogether, how can I put another object on top of all these while they are changing shape and scale each update?

I can draw a boundbox around each gameobject:

  void OnDrawGizmosSelected()
     {
         Gizmos.color = Color.magenta;
         foreach (var mf in GetComponentsInChildren<MeshFilter>())
         {
             Gizmos.matrix = mf.transform.localToWorldMatrix;
             Mesh m = mf.sharedMesh;
             Gizmos.DrawWireCube(m.bounds.center, m.bounds.size);
         }
     }

So, probably the best way to do is to draw a single boundbox around the whole structure and put the object on top of the boundbox, but I don't know how to do it.

Here it is how it looks like. Notice that a certain point the cylinder splits in two and it is where a boundindbox around the whole "tree" gameobject will come in handy:
