The two uppers schools are accessed separately via the end stair cores to the third floor level. Upper School 2 is accessed from its own 1st floor terrace. Upper School 1 is accessed from the southwest corner of the site at ground level. Glazing into the stairs has been maximised for surveillance. The 2nd floor shared facilities can be accessed via the central stair core. The ground floor facilities can be accessed via the most expedient of the three cores. For flexibility of access options, the central core could be used as access for some of the upper school students via the main reception subject to management preference.
