We have a pretty optimal layout, imho. We have several "pods" which are an open 30'x30'x14' room that opens to the main corridor, which get divided into up to 7 cubes via 7' dividers (very modern and colorful, not the vertical carpets of yore). The center usually has whiteboards and chairs for collabs.

So you get interaction with coworkers, but can bury yourself in work readily (also everyone has noise cancelling headphones).

Kinda miss it, it's way nicer than my home office.

There's definitely way less structure now and I am suffering for it.
