Building more than one building at once..

[CCB-STIG]

How do folks, I just want to clarify that I understand that there was a item that would allow you to build more than one building in your hood that's fine, but what I don't understand is how I've just came across some on that in there hood they were building 5 buildings at once.. has any one else came across this, or noticed any one building more than one or two at once?

I'm currently using my phone at the moment as I'm out of the house but soon as I get home I will post a screen shot of this..

Thanks guys and girls
