The new building looks quite different to the original drawing (somehow, the original was more organic, as if it were designed with the water organisms that inhabit the water around the building as a source of inspiration)
I like the drawing version as well. I think as I continue to build and become more proficient at blender I'll get closer to my vision..I hope
My overall idea was for the area to have a coral reef feel so I started with these shell shaped extensions that looks like their growing out of the structures and I added terrace steps for dimension. Everything is surrounded by water that we can wade in and eventually I'll add aquatic plant through out. The larger area (not visible in the screen shot) is submerged underwater, which will be the most challenging aspect of this project. We will be able to observe our hatched water life and emerge ourselves in the the peaceful tranquility of the environment. The hatchery I wanted to be somewhat of a mystery and maybe a little controversial in design. Is it really a building..or something much more? 
If it happens to be an aquarium, then the wizard I’m writing will help loads here
Thats sounds cool! A little magic around the place would be most welcome.
. And it's grown. My build is about 90% below the ground and extended out under other builders shells, which was not good. So I've decided to put what I've built into it's own age, which I am now more convinced was for the best. I still want to keep the shells maybe for a museum. I'm attaching a few ki shots of my Aquarium Age (which I should now think of a proper name for). I have about 20% of it done. I still need to figure out how to make my elevators work, perfect my textures, and build out the hatchery. And most important the aquatic life has to be built and animated..whew! But I looking forward to the challenge and will eventually call on some help from the guild for the highly technical aspect of the build.
