I know this is like my third post in 20 minutes but i have another question! How many huts eventually get built? I have built two but now I have 21 people and isnt a new hut built every 7 people?

You can build three huts. The limit on two huts is 30.

oh okay. well whats the deal with the builders? what do they do while they arent building anything? Thanks for awnsering all my questions!

If you don't have any building jobs for them, you can put them to work on farming or research. Then when you have something for them to build, you can them put them back to building. There is more for builders to do then build huts.

And if there aren't any building works going the builders will keep their hand in by repairing the huts.
