Parenting issue: Building and windows (scaling them as a whole entity)

Another question came about after i solved the main [problem][1] . Now i have to change (by code) the XYZ scale of my building (parent) and the windows i placed upon it (children) must change too according to the new scaling of their parent.

I checked here some parenting forum topics,but did not helped me much, cause the answers were for a specific question on parenting that someone had.

I am aware of the transform.parent.localScale but i do not know how to use it in my case. Here is the code:

 function Start () {
 
 //--Main Building Objects-----------------------------------------------------------
  var oHouse = GameObject.CreatePrimitive(PrimitiveType.Cube);
  var oWindow = GameObject.CreatePrimitive(PrimitiveType.Cube);
  
  //----Start oHouse-------------------------------------------
 //Random ranges between X, Y coordinates
 var RandX = Random.Range(-100,100);
 var RandZ = Random.Range(-100,100);
 
 //Scaling the oHouse object
 oHouse.transform.localScale.x = 7.0;
 oHouse.transform.localScale.y = 12.0;
 oHouse.transform.localScale.z = 7.0;
 
 //Positioning the oHouse object
 oHouse.transform.position = Vector3(RandX,6.35569,RandZ);
 //----End oHouse-------------------------------------------
 //----------------Start oWindow-------------------------------------
 //Scaling the oWindow object
 oWindow.transform.localScale.x =1.1;
 oWindow.transform.localScale.y = 1.116753;
 oWindow.transform.localScale.z = 1.0;
 
 var wind_X = RandX + 2.82102;
 var wind_Y = 11.474193;
 var wind_Z = RandZ + 3.014586;
 
 //Positioning the oWindow object
 oWindow.transform.position = Vector3(wind_X,wind_Y,wind_Z);
 
 oWindow.transform.renderer.material.color = Color.clear; //transparency

 oWindow.transform.parent = oHouse.transform;      //make oWindow object child to oHouse object, parenting
 
 
 var aTopWindows = new Array(); // an Array - a collection- for the top windows
 var i: int;
 var nPosX_TW: float = wind_X - 1.9;
 
 for(i=0; i<=2; i++){
     if(oWindow != null) {//if the object oWindow exists 
         var cloneTopWindows = Instantiate(oWindow, Vector3(nPosX_TW,wind_Y,wind_Z), Quaternion.identity); //make 3 more clones of the oWindow object and place them near to it
         cloneTopWindows.transform.localScale.x =1.1;
         cloneTopWindows.transform.localScale.y = 1.116753;
         cloneTopWindows.transform.localScale.z = 1.0;
         aTopWindows.Add(cloneTopWindows);
         nPosX_TW-=1.9;
         cloneTopWindows.transform.parent = oHouse.transform; //parenting
     } //end if
 } //end for
 //----------------End oWindow-------------------------------------
 } //End  Start()
 

When i changed the scale coordinates of the oHouse object and play the scene, i saw a tiny box in the place of oHouse Building and the windows' scale was remained unchanged. Anyone knows why?
