Looking good, yeah it would be a massive task, specialy working under water Keep up the fine work !!

Update number 3:
Anyone wanna donate netherbrick? I need sooo fucking much xD Also, started a bit of water clearing, forgot how much i hated it... que getting beedobi to do it for me xD Anyways, been building one of the next buildings, which will be the first one, from the first scene from bioshock. Without further adue, here you go (you can imagine the theatrical flare yourself)

WOW thats a lot of brick

WOW that is huge!! I look forward to seeing the finished product. Now back to my nether mining, Theres a guy paying me for nether bricks...... Mine, mine , mine the nether rack put into the smelter, mine mine mine the nether rack put into the smelter........... :)

Wait... you can smelt netherrack into bricks...? Fml

Aww.. Nothing shiny..
Good work though! I'd give you my nether bricks but sadly I'm using them.

oh look! An update!
I hate building underwater, and nether brick xD holy shit
Anyways, The main building is built, and it used so much nether brick. Like, tons.
As always xD My screenshots are done with night vision on, and without. You can tell which ones ^-^

The main building is currently filled with water (im working on de-aquafying it)

Inside is fulla water xD im.working slowly here, ill empty it out and then build the inside

Once i get home set, i can trade all the netherrack i can mine with 1 diamond pick for 4 diamonds and 2 sticks :D then the cooking and crafting is up to you

(Offer only appliesto dannysharks and those who i am told he lives with in that base)

@Dannysharks lol why nether brick?! I mean it looks nice, but what a damn pain to acquire...

Thank you @ardoasms xD you wouldnt believe how many stacks i have used up already. I wont be building a new building for a while, ill be working on the interiors, but i can never have too much nether brick/rack.
And @yelloms because in a burst of creative energy i decided to use netherbrick cause its dark and i thought it would look good (and i was fucking right xD)
Also i was like "Theres so many awesome builds here... lets build one of my own, and damm how much work it would involve!" I hate myself atm xD
Fun fact: this is actually my third rapture. My other two are on creative worlds and only got the lighthouse built before stopping due to reasons such as how to actually do it and clearing a sea bed

Dannysharks.
This is truly amazing. What an undertaking! Very creative and the motif is so haunting. I'd love to visit sometime.
Cheers!

Needs more seeds. Caw.
8/10

As rapture has been raided and griefed, this will probably be my last post here unless I decide to work and build a new one later, which at the moment is low. I don't have much else to say other then that
Goodbye sweet rapture, I'll always remember you
