Another model that I personally found ideal was the small open office. One place I worked had 4-8 people in an open setup in rooms that were conference room type sizes.

It was a great setup as you’d build nice team dynamics and easily talk, but didn’t need assistive technology like headphones and white noise machines to function.

15 years later, I’m probably skill in regular contact with about 50% of the people I worked with in that environment.
