You should rethink everything if you cannot provide those people personal offices who absolutely must be at the office every day.
One thing you're probably doing wrong then is thinking that everyone should be physically there every day.

The central office should, hopefully, stop being the defacto standard for all employees and instead be used carefully for those who need the collaborative environment most, when they need it most. It should be set up explicitly to serve this purpose. At a certain population/productivity density, everyone going to the office every day might be economically unsustainable.
Unfortunately, the places I've worked have taught me that some older folks are going to need to retire before we can get past the notion that any time spent not physically at the office is vacation.
I work from home (I'm a technologist), and love it that way. I can do great work by myself, without much input. But I've seen architects at work, and the majority of their work is collaborative, discussing ideas, coming up with new ideas, etc.
Designing a building draws together a lot of creativity applied at all levels, from the door handles to the shape of the building, and a major difficulty is to coordinate all this to keep the building looking like it was designed as a whole, rather than have all sorts of different styles mixing with each other.
Until architecture becomes a solitary activity (unlikely for all but the smallest buildings, for quite some time), central office spaces will remain a necessity there. This is probably the case for numerous other professions. There's no "one size fits all" work-from-home solution, not yet anyway.
During our 9 months experiment, this is perhaps biggest benefit that we felt.
