SpaceX Starship interior concept for 100 passengers by Joseph Lantz

Joseph Lantz has created his concept for the interior layout of SpaceX's 100-passenger Starship (the passenger capacity goal stated by Elon Musk). Therefore this concept isn't meant for the first crew Starships on Mars used as temporary habitats for the first few years (those first Starships will have much smaler crew). The concept divides the pressurized living space into 8 decks (here shown from top to bottom) and follows a common design choice of a central stairway through all the decks.
