Install concrete canopy afterwards.

We are currently building our single-family house, 180sqm on 2 levels. We forgot about the [Vordach] when dealing with the architect. We want one made of concrete with 2 columns. The ceiling of the basement will be installed on Thursday. Is it possible to add such a [Vordach] later??? What about all the permits then??? We definitely want to do it before we move in. Because it probably will never happen afterwards :)

Of course that can be done later - to my knowledge, a canopy is also a secondary component. It's best to just ask the architect, because they are there for such questions ;)
