haven't heard much about others working on the necessities for living on
Mars. Have any of you heard about others having such plans?

Well there was the Mars One Project that failed in bankruptcy and some
degree of scandal.

The only concrete example I can think of was the Biosphere 2 Project,
that built a prototype standalone habitat out in the Arizona Desert. It
was supposed to be self-sustaining, needing nothing from the outside
once the airlock hatch was sealed. An experiment was conducted that
housed a crews for one year without breaking the containment. If I
recall correctly, the project met with mixed success (there were two
attempts, the 2nd successful). With the main experiment complete, I
think it has been turned into some type of museum and exhibit by the
University of Arizona which purchased it.
