What to build in Minecraft SURVIVAL?

I'm doing a Minecraft Let's Play in YouTube and I just have 8 episodes right now. I just have a small house next to a lake/bay that connects to the sea.

I want to do a cool place to live.

NOT in a jungle biome.

This is my channel BTW

A port with many stores, hotels, schools, banks then houses, like a fishing town close to the lake and connect this with more towns.
