The Ark

The Ark is a mile-long spacecraft on a 100-year mission to colonise a distant planet. The rotating centrifuge provides artificial gravity to support a biome representing all the world’s ecosystems.


The model has approx. 10,000 LEGO elements supported on a custom steel frame and uses LED lights and Power Functions motors to turn the centrifuge. The biome models were built by Rogue Bantha and Inthert; and the circuitry for the reactor lights was provided by Rick Fornalski. Officially a SHIP at 116 studs high and about 110 studs long, as well a MASSIVE investment in parts and time; the project took over a year to design and build. Look back through the album to see some of the stages in constructing this monster.


Because the Corona Virus cancelled most LEGO shows this year the Ark has yet to be seen by a wide audience. Hence, I’ll be presenting an AFOL MOC Talk as part of Brickcon on the 4th October at 8am PDT / 4pm BST where I’ll show the model in detail and switch the motors on to spin the centrifuge; as well as talking about a few other recent builds. Go to to buy tickets. Hopefully in 2021 the Ark will set sail to select LEGO shows in the UK.
