There need to be covered areas of open space so that children can play out despite the weather and so that teenagers have a place to congregate and socialise. There could be roofs of solar panels that then link to car charging stations. There need to be covered areas in town centres, that are shielded from the wind so that there can be market stall, entertainment, pop up cafes etc. There also needs to be enclosed public space so that people especially lonely elderly people can engage and socialise and all people can meeting. These could be large spaces easy to maintain with solar rooves, and fixed seating and then there could be pop up cafes and play areas etc. They would be much warmer than MIdsummer place in MK and would really create a sense of cimmunity. Bill Dunster the architect in his website has some veyr godo examples. This is one of the best. https://www.zedfactory.com/jingdezhen-ceramic-centre .
