Same website but just different content on each. Good idea?

Ok so i have found a nice untapped niche i want to dominate. The competition is low and I own pretty much all the top domain names for that sector (14 domain names in total). I have had one fantastic website built and it has a great framework to it. My question is, if i have 100% new content (writing) on the site, but use the exact same website (framework) will google punish me for this or are they only interested in unique content?

In effect what i'm looking to do is have 14 websites with pretty much the same framework but totally unique content

NO

i am doing this just fine

Wonderful, it cost me a lot of money to have the site built and I could not afford to pay 14x to have new ones haha. Do you feel like there is any punishment or is it 100% fine?

Google has no reason to punish you.

What you have is pretty ideal, one great website framework that (I assume) is flexible enough to be changed around a bit IF needed on your respective domains.

I'm looking for the exact same thing, since I don't want to make 10 different website layouts for 10 different domains.

It makes things so much easier to automate and just go ZEN when you build sites, if you know you always use the same framework. Also when problems occur, usually it will be the same solution on all your sites, instead of 100 different reasons.
