created using precast concrete retaining walls

and an extensive undercroft area.While the

rear of the building – at four storeys high

– makes a bold architectural statement, the

front of the building remains in keeping with

the surrounding architecture of two-storey

Victorian villas and is not dissimilar in size

and shape to the original school. Several

features of the old school have been retained

and incorporated successfully in the new

school, including the clock tower and stone

portico, each of which are now displayed

proudly in prominent positions.


The building comprises a four-storey,

concrete-framed horseshoe-shaped main

teaching and administration block, with a

steel-framed two-storey sports block attached

to the west teaching wing. Columns were

minimised within the teaching zones to

maximise teaching spaces and create internal

flexibility. The post-tensioned concrete

frame solution was designed on the basis of

an 8 × 7.5m grid and a 225mm-thick slab.

The use of a post-tensioned slab allowed

shallower slab depths, increasing floor-to-

ceiling heights and reducing foundation and

column sizes significantly from those of a

conventional reinforced concrete frame.

To ensure the building structure

accommodated the building services strategy,

adequate provision for major services

distribution was incorporated within floor and

ceiling voids, and was unhindered by the level

soffit of the post-tensioned concrete slabs.


A two-hour fire rating was required. The

concrete columns and slabs achieved this without

any special measures, while the steelwork was

required to be fire protected.
