Tips for a wooden cabin on concrete stilts

Hello, first of all greetings to everyone. I hope there is someone here who can give me a few tips. We have a plot of land in Colombia on the Caribbean coast and before we start building our house, we first want to put up a wooden cabin so that we can stay there overnight. The cabin should later be used for visitors. Since our plot has hardly any flat areas and also because of animals, security, and the view, etc., I want to build it on 12 concrete stilts. Honestly, I have no idea about building so far (and no idea about drawing either, as you can see ;-)). The area is 9x4.5 meters, with 2/3 for the cabin and 1/3 for the balcony. Not much will fit in there, maybe a partition so that you can sleep separately and 1-2 cabinets, a table with chairs on the balcony, that's it. The roof is also very light, it's a kind of thin fiberglass. A summer kitchen will come later on the ground floor or next to it, and the bathroom and toilet are outdoors. My first question is whether you think the columns and the associated foundations are okay like this, meaning if they provide enough support or if possibly there are even too many? This drawing is in Spanish but I think it's self-explanatory. And the second question is whether you can download a sketch somewhere for such a cabin and the wooden floor, like how many beams you need for it, exactly where they should go, etc.? I just made the drawing provisionally but already found a mistake. The roof should of course also cover the balcony because of the heat. I would be very happy about any response, thank you very much.

Look, I can't draw either, but this way it's quite simple and stable:

Hello, thank you very much for the tip. I had also considered this type, but I want to make the pillars completely out of concrete. My questions were rather whether the people who know more about construction than I do consider the number of pillars to be adequate and where one can get a sketch for the scaffold of the wooden hut that will go on top of the pillars. Thank you

With pure concrete columns, you need a lot of material and very good foundations, since you are building an inflexible structure. Of course, it is possible, but it would probably be significantly more expensive with reinforcement.
