Chief's Office

Starfleet recognizes the need for department heads to have their own workspace away from their Bridge duties and so assigns each one their own office IF the ship they serve aboard is of a certain size. Usually a department chief's office is located on the same deck as their quarters or on the deck that houses most of their department's activities. The Chief Engineer's office, for example is always located on the deck next to Main Engineering. The Chief Medical Officer's office is always next to Sickbay, and so forth.

Large ships (such as the Galaxy class, Sovereign class, and Vikrant class) and space stations normally have offices not only for each department head, but also for the Chief of the Boat (Command Chief on stations), the Boatswain, and the Quartermaster. On smaller ships, DHs will typically use part of their quarters as an office.

Offices are normally generic in design and lay-out, but DHs are permitted to decorate them to suite their particular tastes. Here is an example for reference.
