Is this open office = for work of a highly creative and collaborative nature, the team owns their own workspace, which they customize as they choose, and folks on the team are in physical proximity? Or is this open office = packing everybody into one huge area like sardines no matter what their job role or what their team is doing with little or no account for ownership? I find we lump a huge amount of stuff into the category "open office", much of it crappy, then stand outside and throw rocks at the entire concept. Let's not do that.
