Basement Corridor
The term "Basement corridor" is somewhat of a misnomer, as there are two adjacent corridors - although one is actually lower than the other.
The "lower" corridor consists of some Technology rooms (Rooms 37, 38,39 and 40), the staffroom, the Server room, the ICT Support office, Mr Clarke's office, Mr Edwards' office and Mr Reeves' office. The Switch Room can also be found here - this is where the Welfare Staff actually live too, it is full of cleaning equipment and some Dr Frankenstein type, rather scary looking electrical switches.
The "upper" corridor houses the Boys Toilets, hundreds of lockers, the Reprographics room (otherwise known as the Photocopier room) and some offices Room 50, which used to be a cloakroom. Mr Grehan and Mrs Kennedy have their offices here too.
