My city is unusual, fair. But 5x ratio would be far from unusual. One could easily find an apartment in Staten Island (not even a suburb, not very far from the city center) for less than 1/5 Manhattan office rent per sq ft.

I'm not sure of your point about sq ft per employee. 10 times 150 sq ft seems like quite a nice three bed.

5 times the office space per employee is going to be huge, especially given that most people already have kitchens and bathrooms.
