The Kleiner Grasbrook site is identified for future urban development as part of the ‘Leap across the Elbe’ metropolitan strategy of the City of Hamburg. Kleiner Grasbrook is an island within Hamburg Port located on the south side of the River Elbe, geographically isolated from the centre of Hamburg to the north and Wilhelmsburg to the south. Improving accessibility to and within Kleiner Grasbrook is required in activating the site. At present, public transport access is limited to the S-Bahn station at Veddel on the extreme west of the site. Kleiner Grasbrook once operated as a fully functioning industrial port, however its use is in decline as port operations have been relocated west to new container terminals. This extensive tract of city owned land, 160 hectares in extent, thus provides potential to be redeveloped, although east-west road and rail infrastructure on the south side of Kleiner Grasbrook must be retained for port uses, isolating the site from the newly-opened Spreehafen waterfront of Wilhelmsburg. Remediation of the extensive brownfields site will be necessary. Preservation of existing heritage buildings is integral in retaining aspects of the site’s history and character. The Hamburg waterfront is subject to daily tidal changes of 3m or more and is also prone to flooding in extreme weather events. Since the Kleiner Grasbrook island is outside the historic dyke structure of the city, water management and flood control must form the basis of redevelopment. The site has views across the Elbe to the traditional city skyline and the new waterfront development of HafenCity on the north bank of the river, with the landmark structure of the Elbphilharmonie designed by Herzog & de Meuron - a spectacular element. The structure of the port with its quays and inner waterways also provides water views within the site. 2009 reports by the City of Hamburg Education Department and the Hamburg Chamber of Commerce, together with design studies by von Gerkan Marg + Partner, identified Kleiner Grasbook as the site for a future campus of Hamburg University.

As part of the Elbe Islands, the vision for ‘HafenCity South’ is for a waterfront development different in character from the HafenCity project on the north which has been designed as a seamless extension of the traditional city, intensely urban like the Speicherstadt warehouse district it adjoins. Currently in construction on a site of comparable scale (157 ha), HafenCity is due for completion in 2025 with GFA of 2.32 million m², 6,000 dwellings and 45,000 jobs. The future ‘HafenCity South’ at Kleiner Grasbrook will have a greater proportion of residential to commercial in its land use mix due to its location away from the city centre. It is seen as a ‘green city’ set within landscape to express the earth shaping and ecological transformations of its site remediation and flood control, and evoke the special landscape character of the Elbe Islands created by a dispersed pattern of urban development protected by dykes, bunds and causeways within meadows and marshes. At the same time, by flanking HafenCity North on the historic riverfront of Hamburg, it will contribute to the future of this great trading port as a Global City of the 21st century. The project has the potential to extend the Hamburg IBA themes of METROZONES, COSMOPOLIS and CITIES & CLIMATE CHANGE by creating a dynamic fusion of residential and employment uses, integrated through social mix and affordable housing with the existing community of the Elbe Islands, incorporating advanced systems of ecological design and flood control.

Strategies Based on the objectives, the following design strategies have been adopted for a development staged over the next 20 years: • extension of the new U-Bahn U4 subway line from HafenCity to HafenCity South with two underground stations in the new development precinct and further plans to serve the Reiherstieg district of Wilhelmsburg; • construction of building platforms on fill above flood-level as in HafenCity but using ‘superdyke’ profiles based on the Rotterdam Stadionpark project to create green slopes to the riverfront as the signature ‘green city’ element of HafenCity South in accordance with the Cities & Climate Change theme of the Hamburg IBA; • extension of the green dykes into parklands maximising public access and open space along the waterfront, including Hamburg’s only city centre metropolitan park on the River Elbe; • creation of a world-class waterfront university campus for the University of Hamburg on the Hamburg IBA Metrozone principle integrated with residential development and employment uses in the Kleiner Grasbrook district, served by one of the U-Bahn stations; • creation of a world class Convention Centre and hotel, integrated with the heritage buildings of the Hamburg Port Museum with views to the traditional skyline of Hamburg and Elbphilharmonie, served by the second U-Bahn station; • excavation of a canal to make the Convention Centre/heritage precinct a special place as an island and to improve tidal flushing; • construction of bridges across the canal and port basins to provide an integrated grid of pedestrian and cycle ways; • construction of floating open space and building types in the port basins on the model of HafenCity marina elements and the IBA-Dock to take advantage of Hamburg’s distinctive tidal changes; • provision of ferry stops in the waterways to connect HafenCity South with HafenCity, the Hamburg CBD, the Elbe Islands and riverfront suburbs; • protection of external and internal views from the raising building platforms by creating view corridors through private development and positioning public buildings to maximise water views; • provision of infrastructure and development blocks by the City of Hamburg on the HafenCity model adopted by the publicly-owned Hamburg HafenCity GmbH development agency, with tenders for fullyserviced urban blocks evaluated on a 70%concept/30% financials basis; • construction of mixed-use developments in the form of street and square defining continuous urban fabric set within a green matrix of avenue plantings and landscape courtyards on the European model, the overall development to have a focus on residential use, accommodating a broad range of socio-economic groups, from high income housing to affordable housing, including student accommodation, on the Hamburg IBA Cosmopolis model; • construction as a staged development on the 160 ha site with completion in 2035 comprising 1.8 million m² GFA, 8,000 dwellings, a population of 20,000 and 21,000 jobs. The project has the potential to extend the Hamburg IBA themes of METROZONES, COSMOPOLIS and CITIES & CLIMATE CHANGE by creating a dynamic fusion of residential and employment uses, integrated through social mix and affordable housing with the existing community of the Elbe Islands, incorporating advanced systems of ecological design and flood control.

Kleiner Grasbrook will be transformed from a working port in decline to a new urban district in the southern part of Hamburg with a diverse range of housing types, cultural facilities and employment opportunities. The brownfield development, principally located on a platform elevated above flood level, will give Hamburg a great convention centre on the Elbe, a remarkable hotel, and a spectacular waterfront campus for the University of Hamburg. It will also feature a new Stadtpark on the riverfront that will provide a unique, large scale public space with views to the city centre and the Elbphiharmonie and a linear park extending into the residential neighbourhoods. A floating dock will provide alternative housing responsive to the tidal changes of the Elbe and extreme weather events. The project will grow for years to become an attractive and differentiated urban community with special ‘Elbe Island’ elements.
Master Plan
HAMBURG BEYOND IBA
HAFENCITY SOUTH
The third stage of the overall Kleiner Grasbrook project will involve creation of a peninsular by the excavation of a canal in the hardstand expanse of a 1960’s container terminal. This will re-establish the early 20th century profile of the Australia-Quai on the former India-Hafen. The peninsula will become the site for an international convention centre, a high-rise landmark hotel, a great public square with access to a station on the proposed U-Bahn extension, ringed in part by conserved heritage buildings from the spice trade integrated with the museum of the Port of Hamburg. The new canal will define the urban space and re-establish the quayside significance of the heritage warehouses. Adaptive-reuse of the old industrial port edges and cranes as part of the Port museum will include outdoor café areas. The existing steel flood-protection wall, painted an industrial green, which divides the waterfront area will be converted to a true ‘green wall’ with plantings. stiles and viewing platforms. The landmark hotel adjoining the convention centre will be scaled and positioned to form an iconic river gateway with the Elbphilharmonie.

Perspective of KENT ST
Location The research trip focus on the part of the Kent Street in the Sydney city area, which it starts at the T-cross of Liverpool Street and Kent Street, and along this street though Bathurst Street, Druitt Street and stop at Market Street. Features Kent Street is one way direction street that it connects between Chinatown, South Sydney CBD and Millers Point precinct, which it is one of few streets connecting Chinatown to Walsh Bay. The part of Kent street from Liverpool street to Druitt Street has four lines for vehicles, two driving way and two parking lines; after that, two driving ways, one parking lines and two cyclist ways were designed on Kent street start from Druitt Street. Kent Street is near the Dixon Street of Sydney Chinatown, there are no many Chinese cultural retails like Dixon Street, instead of it, this street was occupied by many residential and business buildings. The street walls by the buildings facades constructed at least three levels structures, which it would be 10 meters high. As well as, there are many high-rise buildings being on this street which they were made for 24 meters at least. Some modern residential building was designed setback above five levels, which more sun light will be invited into this street to make for pedestrians comfort and green plants. There also are some heritage buildings exiting in this street but no large open space; for instance, the Judge House and Town Hall square. In addition, some buildings used to be a warehouse building but they are for commercial and business utility at the present. Conclusion Kent Street is a quieter street with less traffic than George Street, which it do not include many commercial and business associations but involved many residential buildings. Most buildings for street walls are not high-rise building; however, there are some high-rise buildings established in it, and some old heritage buildings was recycled used which added more levels on their tops. The cyclist ways was design into this street for sustainability.

A NEW HIGH-RISE FUTURE The current Chinatown has very limited gathering spaces. New spaces are provided to boost tourism and a new image stimulates investment and local micro economy. Our visions for this project include increase of floorspace in Chinatown both for residential and commercial uses; to strengthen the pedestrian link in the site area; to encourage 24-hours economy in Chinatown and to increase the quality of life in Chinatown according to projected demographic change in Chinatown in the following 20 years.
Pedestrian Network
Transport System
To achieve our visions we considered future demographic changes in Chinatown, transport links to Chinatown, open space provisions in Chinatown, urban design fundamentals and design controls and codes to ensure our proposed concept.

NEW SHOPPING VILLAGE & LANDMARK This scenario is about to create a new multiple shopping village space and a landmark hotel structure for new high-rise Chinatown area through establishing multiple levels shopping space and 45 stories landmark hotel structure in the Chinatown and the northern CBD. Development: 1.It is an architectural project to create a new general space than Sydney world square but large feasible space for public 2.The sky bridges and multiple shopping space will be walkable in Chinatown; since most areas in Sydney, retails does not work well above ground levels (Pitt Street Mall has provided a good examples – Westfield,which the increasing of floor space has accompanied with the increasing of economic effect) 3.New model of retails involving multiple levels in city blocks to create a large commercial space for Chinatown. 4.Department stores within this shopping village will provide a good public life for Chinatown. Principle: Considering the different view point to the Landmark, which involving to the high-rise buildings of Sydney CBD. Making the interface space through a square for public, which motivate the connection between, world square, New Dixon St, Chinese Garden and Darling Harbour. Creating the serial vision by grouped and blocks to introduce the multiple levels shopping village. Thinking about this project relate to Chinese sense, which creating Chinese culture to public domain. Reference: City of Sydney. 2010, Chinatown Public Domain Plan 2010, City of Sydney, Sydney

EVELEIGH STRUCTURED SYSTEM-Transitional Space The site of the project is a transitional area between a city center carried by George Street and Harris Street to a more residential type of area in Chippendale and Redfern, connected by Regent Street as the main road. The current condition of Regent Street presents an ambiguity of character and the domination of motor vehicles results a lack of public life on the street. The area is also disconnected from the surrounding areas as a consequence of the railway corridor on the east side of Regent Street.
Circulation before & after the New Precinct
Design Intent The principal vision is to utilize the abandoned goods line running along the project site as the central spine of the proposed development. The central spine will accommodate a combined route for a new light rail, pedestrians and bicycles. The implementation of a light rail route in the site creates the opportunity to develop a mixeduse development in the effort to reconnect the west area of the railway to the east side through Prince Alfred Park.

2. Continuity of Streets • Extension of Harris Street by proposing a pedestrian bridge • Continuing the mixed-use function of the Meagher Street by extending the character in the street extension in effort to connect Victoria and Prince Alfred Park • Extending the commercial corridor of George Street to Regent Street 3. Connection of Parks In the effort of promoting the Sustainable Sydney 2030 city vision of a livable green network, the project proposed an extension of Meagher Street to connect Victoria and Peace Park to Prince Alfred Park with a corridor that supports the environment: • An addition of swales and planted trees in along Meagher and Myrtle Street • The shared use of the Myrtle and Meagher Street for motor vehicle and bicycle 4. Reforming Regent Street The project proposed an addition of levels on existing buildings on the west side of Regent Street to provide a higher density of use and to improve the street space and proportion by aligning the height with the proposed commercial center on the east side of Regent Street. The improvement of the street space also proposed a straightening of Regent Street at the intersection of Cleveland Street to form a more well proportion of street intersection space and to create a more direct connection to Redfern Street and Redfern’s city center. A commercial tower is proposed at the intersection as a new landmark of the proposed new commercial center. 5. New Housing Type Providing a mixed-use type of residential and workplace function on the extension of Meagher Street.
