There is no standard answer to your question.

It will depend on your style of play, and if and when, you change it.

What suits you , may not suit someone else.

You can always knock down and rebuild if necessary, and there is always yielding available, which I assume you must already be doing given the low level of mines and quarries.

The time taken to collect a fixed amount of resources is the smallest for food.

Given your lopsided development of resource production,I hadn' t considered that you might have recently started the game, however, in the early stages when bonuses are the most useful, there is much competition for which of them to prioritise.  

Have a look at Hero  experience points distribution,and Hero gear,and VIP,think also about what benefits you could get whilst not actively playing.

I been playing for years. I had this set up for awhile now. All my buildings are lvl 35 now. I want a change up  because having a bonus of Offense, defense and such. I already have 9 lumber. which is Offense. Having 1 of the iron n stone. would it benefit me to add more for defense , Heath, or just keep what i have. think i have too many farms. 

So I was correct,you are not a beginner.

Johns' last comment is largely right, and I stick mostly to mine,without knowing how you play,  what you want to achieve. and what other things you have done, or not done, its difficult for anyone willing to answer your question here, to do so.

There is such little traffic here these days, and not many willing to give away any advantage to other players that do not already know.

I would sugggest whatever you change it's not going to make much difference.

I am not smart enough with the arithmetic ,but would should that updates and sales gimmicks such as ''do this and get X % bonus''  is just to keep motivating playing,expansion and spending,  like a carrot on a piece of string to get a donkey moving.

Though I haven't got nearly as far as you have I cant be certain but am obsvervant and still believe as I wrote before.

In the early stages of the game, bonuses give a much greater advantage to the player than they do later on. This and related things are something you can test for yourself. 

For other tests you would need an alternative account,which the majority of player seem to have, or a willing friend, as was in the case of someone who used to post the findings on the web.

As the game doesn't appear to divulge which military bonuses the resource buildings give.

I have to take what you say about them.I take it you are using none of them specifically for what they produce, but their bonuses.

Having to assume that the old advice hasnt changed.

Health >Defence> Offence.

So you believe this and take your pick, or test it.

I suggest you knock one building down, a farm perhaps if you think you have too many, build one of the others up and see what, if any,difference, it makes to your bonuses and battles.

Or before that, just build one to the next level and see how much it benefits you.

Arithmetic is tricky, 10% can look a lot, but if it's 10% of 1, or >1, or virtually nothing, it's trifling.
