Typical that politicians already signed a treaty guaranteeing that the land on Mars cannot be owned by anyone. Only the structures and equipment placed upon that land may be considered property.

Fortunately, once Martians figure out that they can ignore the previously signed treaties, as in Mars belongs to Martians and not to Earthlings, then they can start to talk real estate. If they start talking about private property real estate before they get there, there may be governmental mandated agreements that anyone going to Mars will never claim any real estate for themselves, otherwise they will not be allowed to fly to Mars.

Remember, politicians, who think they are better than the rest of us, are not our friends; they want all the power and control for themselves.

Would we look at building homes on earth the same way? No. We allow property owners to decide for themselves what kind of home to build. It’s not like there is any lack of concepts.

The focus MUST be on ownership. What good is a great design of anything if nobody gets to own it? When you look at raw land on mars the first thing you should see is real estate.

After the first living quarters are occupied, thinner and thus lighter cheaper inflatables could be used and then covered by rigolith.

We cannot just drop a bunch of inflatables onto Mars and blow them up. Maybe the first small temporary one but after that the area needs prepped. It needs cleared of rocks and leveled off.
Robots cannot be trusted with that.

Atmospheric water extractors should be the first things dropped onto the surface. Solar powered and automated, extracting water from the air and filling tough bladders.
We can drop as many as needed and spend years collecting water.
Eventually the excess power from the panels could be used to help power the living quarters.

With the first people we should also send along the first earth mover/back hoe. Use that to prep the rest of the site. It could also be used to more the heavy habitats around before they are inflated. Then used to bury the new habitats.
