to the left of the original administration block whose entrance is on its short
end. The construction is of reinforced concrete and the factory buildings are
steel framed; external surfaces are rendered in an off-white colour. The administration
block is 2-storeyed with the bronze entrance doors set well back behind pilotis
and with 7 narrow, deeply set vertical windows in the wall above. To the right,
the principal staircase in a glazed door, the only feature to break the austerely
white cubic form of the group of buildings. The factory buildings 4-storeyed

closely set in long horizontal bands and the general horizontality of the building
is further emphasized by the widely projecting flat roof.
