glazed and are insulated with mineral wool and
nutec backing panels. Solar-E high performance
glazing is utilised in the curtain wall system. The
vision panels are double-glazed with clear solar
coating and a frit pattern which reduces from
90% at the curtain wall head, down to 0% at
eye level, on the outer panes. The inner panes
are toughened to resist thermal stresses due to
proximity of internal blinds and potential cold air
from the perimeter cooling system.
The vision panels in the shopfront are grey,
body tinted and double glazed, which matches
the spandrel below. The top of shopfronts also
incorporates a compensating channel which allows
for expansion and contraction of the aluminium

as well as differential vertical deflection between
floor slabs, due to the large cantilevers. This
distinction in glass type and colour, albeit risky,
proved successful in creating distinct volumetric
components in the finished product.
The ground floor of both office blocks is
enclosed by full-height shopfronts. As a scaling
device, a perimeter ‘eyebrow’ canopy wraps
around the perimeter of the building at 2,800mm
above the ground. It was formed in steel and
clad in aluminium to match the brise-soleil. The
‘eyebrow’ is suspended from the underside of the
first office level and extends around each block,
terminating upwards over the entrances to form
signage panels at the entrance of the building.
