Build me a megabase for a high tech...

Build me a megabase for a high tech modpack that has plenty of space for automated machines. Its a sky block, so it should be a floating structure in some way. Make it futuristic looking and functional but look super cool. I want it to be inspired by the architecture and machinery in the game Satisfactory - a factory automation game. The color scheme is usually dark greys, some block and orange colors. Make sure the base is functional, has open entries, flooring, multiple floors if that is applicable. But it should have an inside that we can utilize for factories and other build projects within the base.
