First of all, domes in general aren’t a great idea except for maybe greenhouses - at least on planets in our system. NASA and ESA have done some cool concept experiments as to what pressurized architecture could look like, and it’s a lot more like a cross between a space station module and Earth architecture.
Second - assuming we’ve adapted/evolved to the low gravity, skyscrapers are probably the way to go. That said, if we’ve adapted that heavily we probably have similar adaptations to the atmosphere etc. - in which case architecture would probably be similar to Earth architecture, but able to build higher assuming the same materials.
But if we were trying to colonize a low-gravity world, we’d have to use an orbital station with centripetal-force “gravity” and only research stations on the surface, with a science crew rotation every 6-12 ish months to prevent bone loss.
This is actually the plan for the Moon and then Mars - use Gateway as a station to resupply and host crew rotations for Moon and Mars missions, and eventually to support long-term habitation. But until such a station exists, Lunar Gateway will be used for a waystation for crew rotations between the Moon and Earth.
Space engineering is about to become a very high demand field, on the absolute frontier of human exploration…
I introduce another option, as I’m much more detailed than even “1.” I can visualise entire scenes with the background and all, along with other sensory experiences such as touch, taste, and smell with complete realism. Very useful being in engineering. I do watch the referenced content, but it’s more to “enrich the dataset” so to speak, just for inspiration and to provide more details to imagine later. Sometimes I’ll just turn it off and go with the fantasy instead.
