I was in an airport a few weeks ago and saw a new array of soundproof "phone" booths fitted with laptop stands and high-output lighting, and it occurred to me that I should have started a business building and selling those over the past 3 years.
Anyway, I'm thinking more about city dwellers who generally live in apartments.
I'm with you. But a lot of people still want to live in the city and not go to the office. So, I'm suggesting that, for that cohort, dedicated private offices might be compelling. It means that you probably have a short commute; you can reclaim space in your home that might have been used for work; still live in city and have access to the social offerings there; and that you retain your privacy, and potentially have even more if the case that you're co-habitating.
Higher end 'luxury' apartment buildings are frequently offering FCFS hoteling spaces and also rentable-as-you-need locking private spaces in the building as well as the modern phone booths in various parts of the buildings. If you have the income and that fits your desires you can have the city life and WFthe building you live in.
