Those are beautiful images. But I think we also need more energy efficiency through shared (sound insulated) walls like a skyscraper or big apartment block. A line city would allow you to combine “living in nature” and just taking the stairs down and being in a park or walking between fields and into food forests, go cycling. And at the same time you get high urban density that is needed to accommodate all the people in an sustainable manner. Important would also be high ceilings (3-4m or 10-13 ft) so people don’t feel like in a shitty box. Cheap food delivery or community run cafeterias. And you live among lots of people to meet and party with.

Another idea I had was to just put a big 500 unit apartment block in the middle of a large agricultural area / food forest. Not so efficient in transport, but everyone living there could work on the common necessities, maintain and build their own machinery and be truly self sufficient for food.
