Open offices are good at spontaneous conversation and weak at tasks that need long attention. Noise and movement make it harder to hold a complex problem in mind.
That is not an argument against shared space. It is an argument for switching rooms. At n'Zon the open floor has 39 workstations. Phone booths exist for calls. Private offices for 2 or 5 people give a door when the work cannot leak into the room next to you.
Meeting rooms — two of them — are for sessions you arrange by email or phone. They are not a substitute for sitting all day in the hall.
If your team lives on spreadsheets, legal text or code, treat quiet as infrastructure. Book a booth or an office for those hours, and use the open floor when you actually want to be interrupted.
