Question about a vocabulary (small model of a construction which is exactly...)

[Lady Sun]

Hi every body

I'm new here and I have a little question

what do we call the small model of a construction which is exactly the same as the actual big one?? I'm not sure if I'm clear but this small model is usually produced before the actual building being constructed and used to show the final outcome of construction.

Thanks for every body

It can be called a scale model. If it's less detailed, it can be called a mockup.
