Moving cities dated from the mid 1960s. Here’s a fictional city from the 1970s which is both a utopia and another kind of city. NASA did some work on space stations and this is a drawing they did of one.
Look, this house at the front looks really Greek. Outside is covered and inside is exposed (plus you take an escalator inside, which is totally future). What does that mean? It means outside is easy to live in, warm, certainly, but does it also mean a different approach to the family unit, or that there are servants – perhaps machine servants – to do everything. It’s more interesting in what it implies about how you live in it, than what it is as a thing.
