GROUND FLOOR PLAN The H-shape also enables the office floors to be well lit from three to four sides, depending on the proximity to the atrium. External views are maximised throughout the office space, connecting the staff to their surrounds, and offering opportunities for visual breaks. At all times, the architectural focus is on creating positive good- quality productive working environments. Façade Expression The building is currently the tallest in the area, comprising one basement, seven above ground parking levels, one retail floor, and seven office floors. The fifteen-storey height above ground adds to the building’s visibility and identity, from Oxford Road and the wider surrounding environment. The external finishes of the building are composed of an energy efficient curtain wall construction on all the façades. This curtain wall is finished with a different performance glass, which responds to its aspect. To give the façade some depth, a frit was applied to the glass. A part of the north façade is brick and plaster with thermal and energy efficient double glazing strip windows. These strip windows wrap around the façades overlooking the east and west courtyards. There are several terraces with planting on various floors. The base of the building - the parking structure - is a large element of the façade design. This mass was deconstructed to reduce its scale and made to blend with the street trees through the use of textured and smooth stone fragmented wall panels with a mix of grating and louvres in the openings to facilitate natural ventilation to the parkade. INTERNAL ARTWORK: Transpiration I - Marco Cianfanelli Taking inspiration from the parallels between the complex organic structures of the tree and the neural network, Transpiration I, explores the cognitive process - from sensory perception, through process and, finally, to expression. The title itself points to the process by which water is transported through the tree, from root, through the trunk and is ultimately transpired through the leaves. But, at the root of the word is the term: ‘transpire’, which alludes to the ways in which things come to be known. Bridging the expansive, vertical volumes of Rosebank Towers’ three main atria, the sculpture echoes the organisational structure of the building. Each atrium has an individual spacial characteristic. From ground to upper-most atrium, the building experiences shifts in vertical spacial composition ranging from suspension, to tension and finally to compression. Each sculptural component works in conversation with it’s environment, exaggerating the open space in relationship to the structures that define it. 32 Rosebank Towers
