Yep. Mirrors my experience with shuttles. I, too, have banged out some real work on a shuttle with headphones on. I unexpectedly regretted moving closer to the office because I lost this time, despite that making not a lick of sense.
Offices are for managers to feel that people are productive, not for people to be productive. Look around most offices and there is absolutely no space laid out for concentration time, except social concentration time.
