There are separate rooms (usually hosting about 3 to 10 devs) at the place where I'm at right now. The previous company where I worked eventually ended up with open floors - once they grew and moved to a new building - but also provided closed rooms in the location before that. I also happened to worked at our client's office, a large IT company based in Berlin, they had rooms again. YMMV - depending on your location perhaps - but based on my experience it's not extraordinary at all.
