Everyone in the building I was in had a private office with floor-to-ceiling exterior windows and a door that closed.
Groups of offices shared a larger open common room with sofas and comfy chairs and coffee tables conveniently arranged for sitting around talking. There were white boards in the offices and on several walls of the common areas.
You need to concentrate? Go in your office and close the door. Feeling amenable to visits from colleagues? Open the door. Feel the need for free-form conversation with one or more colleagues? Plop onto the couch and talk things over.
NeXT was laid out somewhat similarly, but with less convenient common areas.
At various times I've experienced wall-to-wall private offices, giant open rooms with everyone side-by-side on long tables, and everything in between. For my money, the Newton office was the best. Privacy and camaraderie were available to us at all times in whatever measure suited each of us.
