The corridor, or galley, incorporates storage and work space on both sides of the room.
The Pullman style is similar to the corridor but allocates everything to one wall.
L-shaped kitchens fit storage and work space at a 90-degree angle into the room.
A U-shaped, or peninsula, kitchen wraps such spaces around the entire room.
A fifth option, so to speak, is an island, which can be combined with any of the previously mentioned layouts depending on its size.
