How do I do this quicker?

[machopenguin001]

I'm adding some balconies to a wall in a map I'm making (secret map, you'll all be dumbstruck when it's done ), I just made one, but now I have to cover a side of the wall, that would take some time to remake every single balcony exactly the same, using vertex and polygon create. I'm looking for a way to do it quicker. Any suggestions? Making the individual polygons and stuff and then specifying it's exact position in XYZ, for every vertex can take a loooooooooooong time.
