Private bathrooms for every employee? No commute? The office can never "feel like my home", my home doesn't have my co-workers in it. It's an environment 100% of my design.
When I look back over past jobs, the question I wish I had asked more in advance is where will I sit here? I am never going to work in a barn again. It's not just about open plan seating, which has pros and cons. But when the company stacks people like boxes, it turns out they think of you as something fungible.
We had a nice setup for awhile that was a central meeting/conference/open area, with offices all around it, each of which had a large window looking at the meeting area. You could close a curtain if you really needed to, but otherwise it was sound-proof; people could easily see if you were available but you could work privately, make calls, etc.
I'd be willing to consider commuting for something like that again in the right job.
