A combination of open and closed areas: Closed areas for meetings, calling, and deep concentration. Open areas for side-by-side coding and colaboration. Usually marketing and sales can work anywhere: give'em an open space. Also give them a closed place where they can call confidentially a client without developers/pm hear them. Project managers are similar, put them near sales and development teams. Devs need to remain focused for 1-2h runs, and might need to do pair programming or just get help. If you bring them an open space, gift them with deep concentration cabins, and/or meeting rooms for 2-3 people. Sysadmins need something with a door to make some friction between the team and them. Otherwise people passing by will ask them anything possible. If you don't have such space they will migrate silently to the datacenter. Data scientist need absolute silence. Closed spaces, rooms, etc will work. If the place is not quiet enough consider renting some space at the nearest churh and install wifi there (not kidding).
