Development tunnel Central station George street Mechanical Signage Meeting F&B Outdoor Amenity City Views Light weight Shed Sense of Place – Sense of Country The idea of Country is drawn from a sense of belonging. When Aboriginal and Torres Strait Islander people speak of Country, it is about the place of their ancestors, stories, lore and knowledge. Country is what sustains us and is therefore as much a cultural and spiritual condition as it is a scientific one. It follows that within this knowledge capital there exists endless opportunities to engage with and affect the cultural and built capital of the project and precinct. Our underlying belief is that Country is the first point of connection to creativity and science and an awareness that creativity and science has existed in Australia for over 50,000 years. The ambition of the designing with Country framework we have established for the project is to enable a greater relationship between People, Knowledge and Environment and work towards A Non-Conflicted Future. This ambition can be realized by acknowledging the significance of Aboriginal and Torres Strait Islander heritage in the development of the built environment. As the flagship project of the new Central Precinct, the Atlassian Central tower connects Sydney to the heritage of the site while catalysing its future as Sydney’s premier tech hub TheAtlassian Central design aims to uphold and reinforce all major Central Precinct objectives—anchoring the precinct, creating a vastly improved network of pedestrian connectivity and raising an icon on the skyline that will serve as a signpost for the newly activated, 24/7 life on the ground. Contextual Response & Urban Identity The tower we propose is designed to serve as a thrilling and appropriate symbol for the Tech Precinct, extending its identity into the sky. The tower openly expresses its complex program through the divisions of its massing, and, by carrying gardens upwards as far as its green roof, honours the on-site convergence of the city’s greenways and the ecological values they represent. An Activated Community A city’s public spaces are only as good as the civic life they support. Our proposed design brings dynamism and delight to a purposeful pedestrian accessibility plan through the use of strategically deployed active programming throughout the site. Acting in a sense as a publicly-accessible Atlassian “community” at the urban scale, the Incubator allows opportunities for the activities of that enterprise to be in further contact with, and service to, the community at large. A memorable identity founded on the adaptive re-use of the heritage listed former Inward Parcels Shed has been developed for the public realm of the Link Zone. While this space will be experienced as a transient ‘urban threshold’ connecting the northern Third Square with the southern Devonshire Street Tunnel and reconfigured Henry Deane Plaza, it will also serve as the ‘front door’ to the two level Atlassian Lobby. It is conceived as being spatially and materially integral with the upper and lower Shed spaces. The lower ground Link Zone is considered as the heavyweight base to the lightweight timber Parcels Shed. It is this contrast that elevates the Parcels Shed and clarifies the reading of each of the key elements and spatial experiences. Historically the base was made from robust brick, concrete and steel elements, with a key feature being the jack-arches that form part of the upper ground slab. The proposal has developed a contemporary interpretation of these elements along with the retention of some of the existing historic fabric and has identified opportunities for interpretation and reuse of existing fabric into the public realm design. _______ Public Realm Design The site Atlassian Central Tower is located at 8-10 Lee Street. The main access to the tower is made through Lee street. There are also accesses through Ambulance Avenue in the north and Devoshire Tunnel and Henry Deane Plaza in the south. Most of the historical components of the site are retained in our plan, and optimized for new, compatible uses. The surrounding public realm creates a series of varied, processional spaces as one exits the Metro or approaches the station from the west. It also serves to frame the preserved Shed structure. In a double height space extending from the base of the Shed to its high gable, the lobby entrance to Atlassian fronts the square, bringing life to this key public space. Above, the Atlassian Incubator and YHA hostel lobby are found within the historic Shed structure. _______ Preserving Heritage Serving as a secondary access route to the south at grade, the Link Zone path extends the energy of the new Central Square into the heart of the site and, via Henry Dean Plaza, the balance of the Tech Precinct. Natural light and a visual connection to the upper level is provided by several apertures opening above the wide passage, an updated urban arcade. Services and retail amenities fronting the Link Zone are positioned to support student life in the nearby universities, as well as Hostel guests and those working in or visiting the tower. Placing the Atlassian lobby upon the Link Zone itself heightens the sense of urban vitality there, and ensures direct and fruitful contact between all of the communities active on the site. _______ Diversity of Experience The around-the-clock dynamism of the Tech Precinct is promoted by thoughtful design at ground level and signaled on the skyline through the character of the tower itself. By day, the planted terraces aremore prominent as the environmentally-performative enclosure catches the light. By night, the warm wood of the habitats comes to the forefront, creating a welcoming presence. The contrast between the new construction and the historic architecture of Central Station, with the Shed serving as a zone of transition, creates a composition that speaks to the vitality of life in Sydney, past and future. _______ A 24/7 Precinct Located above the final mega-floor and sloping to follow the intersection of the tower’s edge with the sun access plane to the north, this area is an interlinked series of enclosed and open-air spaces that create a unique rooftop community. As both a unifying gesture and a functional element, the last two levels of the Crown feature plant rooms that replicate the double-layered facade system common to the balance of the tower. The key element of these levels are the ample planted terraces that activate the roof scape bringing users to enjoy the unique vantage of the amazing skyline of Sydney. Tall cantilevered glass balustrates are integrated with landsccape at crenellated edges to protect users from wind with virtually no visual impediment or shadow. _______ The crown spaces “We acknowledge the Gadigal people of the Eora nation as the traditional custodians of the land on which the project stands, and recognize their continuing connection to land, waters and culture. We pay our respects to their Elders past, present and emerging.” ____ _______ _______ __________ Words of wisdom “The brief for the project included the mandate that it should create a skyline icon for Sydney’s Tech Central district,” Bill Sharples said. “But the primary drivers to achieve that iconicity were the quality of the civic and social experiences of its spaces and the overarching goals of the tower’s environmental performance.” ____ _______ _______ __________ SHOP Co-Founder William Sharples We care deeply about setting a global example of how a high-rise built environment can achieve key sustainability metrics without making fundamental trade-offs around look, feel, quality or cost. We are also passionate about place-making in Sydney and relocating the city center from the current CBD into the transit hub of Sydney to allow for a more democratic experience for local population. This will be the first long-term home for our Atlassian Sydney team who have moved at least 5 different times since the company was founded in 2002. We are thrilled to create a working environment and building envelope that truly captures the Atlassian journey over the years and speaks to the long term commitment to placemaking in Sydney- our Global Headquarters. ____ _______ _______ __________ Atlassian, Global Head of Workplace Experience Scott Hazard SENSE OF PLACE _______ Street views
