This building is inspired by the ones from LEGO Rock Raiders and made for LEGO Rock Raiders Fans. The building is what I think a LEGO Rock Raiders Headquarters would be like on Earth. It has the fallowing retired colors: Old Gray (what Bricklink calls Gray), Old Dark Gray (what Bricklink calls Dark Gray), and Metalized Silver (what Bricklink calls Chrome Silver.) It features a garage to store various vehicles and tools. There is also an x-ray room for x-ray Energy Crystals, and it also has other things that Rock Raiders can do as part of research when it comes to mining.
