Any good Minecraft building ideas?

I built a bridge in mid air with a sorta like platform connected to it to build buildings

Flying/hanging gardens and forest

Build something unique, I'm currently working on building my street, I've gone out, taken pictures as references and working on a 1:1 scale or my street using Google Maps for the dimensions. It's a tough build but I like a challenge, can't stand building things everybody else has such as a bridge, the Eiffel Tower or the Empire State Building.

Try to build what you want. I would build four houses of the elements with actual references to which element it was as in the water one being in the water and the ceiling spiraling up into three stories with water pouring down the outside and coming in the middle of the attic roof and flowing down to the basement. Just an example.
