The combined effect of this is not only a finely balanced façade but also the integrated provision of shading to the bottom floor and a balustrade to the top floor. Due to the Centurion 45 degree street grid relative to north, the triangular corner of the building is extensively shaded. To the north west, this shading takes the form of larger vertical fins made up of steel framed aluminium louvres, while the north eastern side is shaded with a large rusted metal screen made up of vertical flat fins of varying depth and thickness. This creates a dramatic effect externally as the view to the building opens up as one moves past the building along Heuwel Avenue. From inside, one senses both privacy and transparency depending on the viewpoint. Internally, the common parts of the building are designed to be modern but warm and comfortable, with natural graphic themes and accent lighting providing focal elements. The office space is uncluttered and light, with feature pause areas on the ‘bridges’ over the atria. Roof level landscaped entertainment spaces complete the end user experience of each building.
