New "community" build and need advice

Not self promoting

Hello, i hope you can all help me out on this one. I am an American who now lives in Thailand and we recently bought 2+ acres of land here that we will develop then build a few houses and a sort of community building on. It also has a lake.

I dont have really any building experience, i have done a few DIY things to my houses back in the US but ya. We talked to probably 15 builders before we landed on the one we are currently going with, but Thai builders are notorious for... not being up to par haha.

I was wondering if i kind of made like a YouTube series. And sort of documented it etc, would you guys be able to give any tips, corrections, errors sort of thing on it? Or i guess just general interest?

Tomorrow we are starting the build for the retaining wall, because we have to pile in a ton of dirt to level the property off with the road. It used to be a rice field so ya.

Again sorry this isnt meant to self promote, i just want to make sure everything goes well.
