As far as I know, no one is mandating that every comes in the same day. So you can reduce the office space by some percentage, assuming people come in on different days and not all at once. If you have 10 teams of 5 people each in an office, in a 3/2 hybrid setting you can expect you'll have 30 people in the office. You can pad that to go to 40 people in the office on any given day -- this gives you a 20% reduction in required office space.
