Just had this conversation with an architect friend who lives in Palo Alto. The whole idea that there is a "residential zone", "commercial zone" etc needs to go away. Now with people leaving cities in droves there is an amazing opportunity to introduce mixed zoning into office areas by converting many of the empty offices into lofts. This will solve our urban housing problem. Despite what people are saying now about remote work I don't think the majority of people will leave cities long term. Cities offer facilities, infra, amenities, network and culture. We need to make cities livable and walkable.
