If you're building a house no more than 3 stories high then regular wood construction with 2x4s spaced every 16 inches is plenty robust, unless you expect to be hit by floods or hurricanes. And if you do expect hurricanes then wood isn't a good option regardless of construction.

One answer to the robust question is to build an eco house, perhaps partly underground. You want sustainability? Aim for more than structural integrity, but how it related to its environment and social structure.

Here's a clickbaity-but-useful-article showing some different designs, and the Welsh Preseli community is particularly interesting for there sharing of designs. A quick google will find you lots of resources for all budgets.

>If I want to build a robust wooden house, where should I go

Your local lumber yard. Wood is cheap. The easiest way to make a robust structure out of wood is to just use more material than you normally would.

How robust? Search for "timber framing", there are schools and builders who specialize in it. And of course thousands of hours of YouTube like with any craft.
