Change length, breadth and height of geometry on run in threejs

Question

I am working on a configurator in Threejs for which I have a scene in which I load a model gltf, it has various elemenets in it like a real scene. For example inside office scene where we have a table, and on top of table there is notepad and pens. Apart from table there are some chairs and other material as well.

Now I want to give user a feature to change length, breadth, and height of any table or some other materials.

For this I have tried changing:

1. scaling of the material:

   textureMaterials.scale.x = 1.5;
   textureMaterials.scale.z = 1.5;
   

But the issue is that by changing the scale the position of the material also gets changed, and suppose even if I set the position of the material and show it at right position then the stuff which is placed on top of that table remains at its original position.

So there are a lot of things related.

Please let me know what is the good way to do this?

Thanks
