The cook is a professional, and while his assistants may sleep in the kitchen at night, he'll demand his own quarters. The kitchen will need a storehouse for coal or firewood. It will have a large kitchen for preparing meals. Firewood will need to be plentifully supplied if the air is chill. It will have a large common room for socializing and taking meals. In D&D, since invisible creatures are a problem, it will almost certainly have a kennel for housing at least dogs to help maintain the security of the fort.

There will be a pigeon coup with messenger pigeons or some sort of trainable species that can be used to communicate with other fortresses. In large D&D forts, there will be a small force of aerial cavalry to at least act as scouts. The stables will have a goodly supply of hay in lofts and barns. It will have a stables for at least messenger horses, and possibly cavalry units. In this manner, access to the main water supply is heavily restricted. The cistern will supply water, and if corrupted will be emptied and replaced by water from the well. Water from the well or spring proper will be pumped or otherwise transported to a ready cistern which will be slightly less guarded than the well, and inspected regularly for corruption (via detect poison or the like). In D&D, the well or spring proper will be secured against magical attack and have a set of double doors which are guarded against invisible creatures and the like. If a spring house, it may also have an adjoining cool room where food was stored chilled by using the water from the spring to cool the room. It will have a well or spring house with abundant water. It may have a barber for treating minor ailments, pulling teeth, trimming hair and beards and such like. It will have a hospital of some sort for quarantine and treatment of the ill. A military fort is a small functioning city.
