Mars colony apartment block

British The Sun has published an article what the human residences on Mars could look like by 2050 with architects and scientists prototyping several possible types of homes for would-be Martian colonists. All the designs are meant "to protect interplanetary homeowners from hazardous cosmic rays, space radiation and Mars' severe dust storms, as well as insulate them from the cold."

Here are images for the 2nd design - apartment block covered with Martian regolith.
