I've been searching the forum for answers, but thus far have foud none, maybe someone can help me.

I have 2 Adept Builders, but no idea how to make the Master Builders?

I have built the small cabin, fixed the "love shack" (you can figure out why I call it that), built the dam.

I've fished, harvested coconuts, started farming but my crops are getting low and my tech points are even lower.

What do I need to do next and how do I get Master Builders?

What I do, generally, after the dam is: (highlight for spoiler) to purchas the level 2 of Exploration and with a master scientist, I build the cutting tools (puzzle 4) for clearing the thorns that are behind the research table (end of spoiler)

Thanks for the suggestion, I was sort of stuck in la-la land wondering what I do next. Will that also help me towards Master Builder?

yes! this kind of work also makes builders!

Thank you so much!
