There is no doubt that cities on the moon will be built underground. For astronauts who have been on the moon for a long time, radiation from the sun and the universe is an important issue, and the cheapest protective device is epidermal soil. We obviously need places to connect to the lunar surface, but these sites should be small and not permanently habitable.

There will be a huge underground greenhouse here. Because we need to stock up on food, produce oxygen, recycle waste, and ensure human mental health, it is difficult for us to overcome the difficulties of the greenhouse. Every kilogram of material transported from Earth to the Moon costs thousands of dollars, so our goal is to get the recovery rate as close to 100% as possible.

Above the base will be a huge array of solar energy. Solar energy works better on the moon than on Earth, so there's no need to worry about the atmosphere. The base also needs an important battery pack to store energy during the long nights. At that time, it may have been possible to develop a better energy storage device than a battery, but something was still needed.

Especially in the beginning, space is limited. Building a small bunker-like building is a good foreshadowing. But it is obvious that in psychology we should build a base. There will be artwork, sunlight coming in from the lunar surface and a library (electronic library, of course).

Eventually, there will be a gymnasium here. One-sixth of gravity would cause serious damage to the astronaut's body. There may also be a centrifugal separator that allows residents to experience first-hand an environment that is more gravitated than they would normally experience. We need a lot of research in this regard. (Is one-sixth of gravity enough to keep astronauts healthy?) If not, how much gravity can be raised to achieve a condition that keeps astronauts healthy? But there's no doubt that residents here need to be active.
That's a good question, and I think the answer to that question depends entirely on whether technology can alter gravity or whether people can accept one-sixth of Earth's gravity. These facts affect many things because on the moon an average person should be able to jump 5 or 6 feet, there is no doubt that urban architecture and urban planning on the moon will also refer to this fact. The basketball hoop on the basketball court will be twice as tall as on Earth, or we won't change the height so that everyone can have a Grand Slam.

I think architects will consider this so that the buildings that are designed can make people jump around. Because the gravity on the moon is too small, you won't fall to the ground very hard at all, so the probability of injury is very small.
But in order for this life to work, people will build some kind of dome with artificial atmosphere, after all, who wants to wear spacesuits all the time? So I think this life would be full of man-made objects.
Since the moon is gray, I will be able to imagine planners using more colors when building cities like in some similar cities like in Italy. People in Scandinavia are known for their bright and happy living spaces, as there are six months of the year where it is dark.

So I think the roof will be very high on the moon for some obvious reason, and people will be more concerned about the inner space than in the outside world.
