Corner of Castlereagh Street and King Street

This site created by the junction of Pitt Street Mall, Sydney Tower, Castlereagh Street and King Street will compliment my studies of the Diagrid. Sydney Tower has a distinct image of a ‘golden crown’ that sits on a large column supported by an intrinsic lattice of cables (Figure 1). These iconic elements would be complimented greatly by the similar style of the diagrid. The buildings close by the tower could have the same theme of support that the Sydney Tower possesses, thus creating uniformity as well as a visual harmony.

The site is a hub for many high label brands and attracts many visitors from its pitt street mall pedestrian walkway. Interesting bold diagrid arrangements work around the pedestrian area.

Diagrid Experimentation

After researching some tutorials I created this preliminary diagrid algorithm. It divides the curves and connects each divisional end point to the other curves next proceeding point. Using item lists and series nodes I was able to produce the cross references that make the wireframe of a diagrid. The 3D form was created by applying an extrusion node along the lines z axis.

I would want to achieve some sort of tiered level, created by stacking diagrids that offset inwards for each level above. The Swiss Re is a great inspiration, and I would like to be bold and all the while represent something new within the diagrid form.

The successive tiers could be soild and without windows. The offices or residentials are separated from the open ground floor. This floor area would provide more space for pedestrians to circulate and provide natural illumination and air flow for sustainability and efficiency.

Glass paneling between the diargrid’s support columns will be filling the gaps throughout the lower tiers.
