Minister for Magic and Support Staff[1] is a section of the Ministry of Magic located on Level One of the Ministry. It is comprised of the Minister for Magic, the highest position in the Ministry, and the Minister's support staff, who assist in the daily administration of the wizarding world in Great Britain. Given the direct access to the Minister these staff appear to enjoy, it is likely that these positions are high in the hierarchy of the Ministry and are separate from the normal Departmental system.

In Level Two, you can find the Auror Headquarters, Hitwizard Office, the Misuse of Muggle Artifacts Office, Improper Use of Magic Office,and the Wizengamot Administrative Services.

Level Three houses the Department of Magical Accidents and Catastrophes whose employees hold the responsibility for repairing accidental magical damage. The Department of Magical Accidents and Catastrophes includes the following offices:

Accidental Magic Reversal Squad
Obliviator Headquarters
Muggle-Worthy Excuse Committee.

The Department for the Regulation and Control of Magical Creatures is the second largest Department in the Ministry. The Department incorporates the following offices:

Level Seven houses the Department of Magical Games and Sports, which is responsible for organising sports events the likes of the Quidditch World Cup and the Triwizard Tournament, as well as enforcing game-related laws and regulations. The Department has a very relaxed ambiance, the corridor off the access lift being somewhat "untidy-looking" in comparison to the other Ministerial Departments: various posters of Quidditch teams are tacked lopsidedly on the walls. Magical Games and Sports incorporates the:

British and Irish Quidditch League Headquarters
Official Gobstones Club
Ludicrous Patents Office

On Level Eight one finds the Atrium, an area that serves as lobby and reception room to the visitors and employees. The Atrium is a very long hall with a highly polished dark wood floor. The ceiling is peacock blue and is filled with golden symbols that keep moving like a notice board. The walls on each side are covered in gilded fireplaces: the left-hand side ones serving for arrivals and the right-hand side ones for departures. Halfway down the Atrium lays a statue: A wizard raises a sword high while a witch has hers plunged into the twisted form of a demon at their feet. On the far end of the hall one can find the Security Desk, the Ministry Munchies café and a set of double golden gates leading to the at least twenty access lifts.[1] in a room off the Atrium, one finds the Security Office, a room containing spare keys to the offices and lift information.
