specific parts of the precinct , creating optimal outdoor lounges for all seasons .
The building mass expresses different characteristics from different vantage points . Viewed from Sable Road to the south , the blocks take on a sober , linear articulation , maximising the views of the mountain and creating a robust edge to the road . From within the precinct on the north end , the masses all shift and turn moving towards and away from the site boundary , creating a more permeable edge and resulting in a series of habitable forecourts that encourage pedestrian activity .
Structural Approach A large part of the building ’ s concept was manifested in its structure . Creating distinct floating boxes that veer off and cantilever beyond one another was one of the biggest challenges . The engineers and designers worked closely together right from early concept phase to put the pieces in place to achieve this .
The most challenging aspect of the project was the buildability of a ‘ shadow gap ’ between the boxes to make them appear to hover above one another . To achieve this , a complex double slab component was introduced . The gap is achieved by a perimeter concrete downstand beam projecting into the ceiling void below , and extending outwards to form a protruding flange , or architectural slab , to echo the plan of the floor slab below . The reality of this component was questionable at times , but the desired result was achieved . The ‘ shadow gap ’ occurs at every instance where the two distinct boxes come into contact ; which is just below the second floor , when the layered double height mass is on top ,
or just below the third floor , when the glass cube is on top .
Façade In accordance with the shifting floor plates , two systems of glazed façade have been installed over the three levels of office . A deliberate , yet playful interchange of these systems contributes to the aesthetic complexity of the building .
The façade activity is borne out of both the North and South blocks being inverted creating a set of four similar yet unique blocks . The atrium is contained by full height double glazed curtain walls on both the entrance and the rear faces of each block . These vertical link the alternated
