Highest update level of buildings

It would be great to know what the highest update level of a building is, so maybe you could add that information into the game something like this : "hut of the brave level 5 of x (I don't know the highest level yet, I'm not that far *g*) "

Anyway, if anyone has reached the highest levels could you please post them here (like make a list), as I would really like to know what to expect.

So far the only I know is huts can't be upgraded higher than lvl. 5 (towers as well, but that's just because classical age tech is not ready yet).

Hut = level 5

Chieftan hut = level 10 (this also means you can only have 10 of the 'normal' huts)

Shrine of knowledge = level 10

Haven't hit any of the highest levels for the others.

Some things need a blue print to get to number 10 and I don't have anymore.

Forestry needs blue print to get to level 10

Garden needs blue print to get to level 10

As you have already said max level for huts is Level 5.

Virtually all other buildings have either 10 or 20 grades with no obvious pattern or law.

Farms and mines have 10 levels. Storages have 20 I think. Most of military buildings e.g. Hut of the Brave can be improved up to Level 20, with some exceptions though.

Also, later in the game, when more technologically advanced epochs are reached, some buildings can be rebuilt into their more modernised counterparts.
