Having green houses attached to our buildings is another idea. Using earth-friendly materials is also important. Things to consider. A main room or lodge would also be ideal as a place to have group gatherings, feasts, dancing, storytelling, etc. Privacy is important to everyone .
Kitchens are the most commonly difficult community spaces.
We will see as we go, but we are likely to have one large public use kitchen, even if some people have small kitchens of their own. Cooking and cleaning on a rotation basis seems like the thing to do for dinners, and hopefully people can be responsible even not to let things get too out of hand during the day. That makes it easier not to get into the habit of leaving things out and using another one. You'd just use your own. It is just another way to have little reminders in everyday life to keep good habits.
