I'm in the process of building a Titanic replica in Minecraft. It's the Xbox version, so I'm unable to share the file. Right now it's about 30%-50% complete. E Deck is finished, most of D Deck is finished. The boiler rooms are almost finished, except for the steam piping and the front of Boiler Room #6. The forecastle and forward Well-Deck section is complete through all decks. Much of the ship's exterior shape is in place, and it's now mostly a matter of finishing the engineering spaces and decks A-D, and the Boat Deck.
Not much for way of shiny furnishings, but it's a good way to walk around the decks and get a feel for where everything is.
Everything in Minecraft is in meter-resolution, so there are a lot of places I've had to fudge and an unfortunate number of staterooms I've obliterated since all the walls are 3 feet think.
