 It is easy to spot the walls that were subsequently added, as all the permanent walls in the building as originally built are concrete block, while those added later are made of drywall.Additionally, to cut costs, the ceiling tiles and grid were not rebuilt to accommodate the new walls, which makes for a small gap at the top and reduces noise insulation.Some of the lockers were painted a neutral beige color, while others were painted dark blue (one of the school colors).
