Started on Making an Island and have had build height issues with the stone. i can put structures on top of it. but can not level out the rock. looks like a wave lol.

plains island base with room for crops is definitely on my list

island base, eh?
1) you may want to raise the terrain a bit so that in storms it is not knee deep in water in your home. Its harmless -- your fires go out, but they are right back up and running when the waves roll out, but I personally found it annoying.
2) you want to be able to get onto your island from the water if you end up inadvertently or intentionally even going for a swim.
3) you probably want a boat dock. combine 2 and 3 and shape the terrain and such accordingly.
4) its worth the time to find a decent island. There are a great many that are way too small, and you realize it about half way through your build. If you are not great at estimation, try putting down 2x2 floors the size of your new mansion and make sure everything fits.
5) if it does not fit, you can raise terrain a goodly way out into the water, but eventually you will hit a max size. This is a lot of trouble, if you can find a bigger island to start with instead.
6) you want to be far enough from shore that enemy on the shore can't really see and notice you. Its not that far to do this; my best island has a land bridge of sorts that you can wade to the mainland and enemy can wade or swim to me, but its far enough that they don't because they can't see me or notice me at that range. If you can't hit them with a bow from your home, they usually won't see you. (assuming that you can't hit them because of range, and not because you can't shoot well).
7) do not build on islands with barnacles all over it :P

Good luck finding a spot!

I'm thinking this is what he has in mind...

How high is up to you but I'd recommend high enough that the large waves that come with high winds and storms won't wash through your base buildings.

Yeah I know about the workbench preventing spawns. But how big should I build it up? how much room would I need for a decent crop to grow? etc.

It doesn't take much room at all to grow more barley than you'll ever need for a single person. If you can plant 200 barley, that's already bordering excessive, and you could do that with a very small farm plot.

Here is my current island base...

That's pretty. Looks like a zen garden or something.

Man.. You can't tell a VIKING his base is PRETTY. (But THANKS!)

If you look at the mini map upper right you'll see two islands. I actually connected them and made one big island.

Trolls are a joke by the time you're up to the plains, and if you do an island base right, nothing will ever spawn on or around it.

Don't know what kind of tips you want. Are you looking at creating a spawn-free zone on your island? If so, use workbenches to initially neutralise the spawn on the island, since you can use their build radius indicator to see how frequently you'll need to place them to make the no-spawn zone overlap. Once you're done with that you can replace the workbenches with whatever other spawn-inhibiting structure you want.

Any tips from anyone who has? (I'm thinking probably plains so I can easily grow more flax & barley. I have all building pieces unlocked currently also.

Friend me! let I'll show you my island base. Its in the plains, Its on an island...its safe, I grow barely. I love it. If you like my spot...you can even play the same seed.

I thought trolls could only wade in the shallows

I mean... Technically every land mass in the game is an island so every base is going to be an island base.

Just one:
Trolls can swim.
