  • 4CONTEXTAuckland is New Zealands largest city, commercial centre and home to a third of the population. It is the dominant commercial focus of New Zealand with its large domestic market, infrastructure, port and airport, commercial expertise and diverse manufacturing and industrial base. It is also one of the fastest growing cities in Australasia. Alongside this growth is a growing demand for business, housing and a consequent increase in our use of infrastructure and natural resources. Growth and development provide new opportunities and make Auckland an exciting and vibrant place to live. However, if not managed well, growth can affect the health and amenity of our natural and physical environment that we value highly.

    Home to just over 6000, Karaka is traditionally a rural district, with only around 2000 homes that inhabit the area today. A young population with a median age of 38, Karaka is best known for its production of thoroughbred horses and sales that attract buyers from all over the world. Currently the area is being used as farmland, this is due to its highly fertile soil, flat open spaces and ecologically rich environment producing high quality stock and exports. Before the forming of the Auckland super city, Karaka was part of the Franklin district about 30mins from central Auckland. Surrounded by the Manukau harbor and boarded by Weymouth to the north, Karaka has the potential for a substantial urban development.

    With the urban sprawling pattern that Auckland is going through, Karaka is in an optimal place to develop. Taking inspiration from other rural developments like Flatbush and the Albany transport hub, Karaka can be transformed into an example urban development, showcasing innovation and ecological planning. Planning a site that is at its forefront of modern thinking and accessible to all forms of public transport, creating a community that can set a standard for Aucklands progression.

    CHOSEN SITE FOR DEVELOPMENT

    SITE CONTEXT

    SCALE: 1:40000

    An increase of 1 million people is said to sprawl into Auckland over the next 30 years, which will require a total of 400,000 dwellings. The key focus is not solely on where we pinpoint our dwelling allocations, but also on integrating the existing qualities of the landscape with the developed zone to create a co-existing system.

    With consideration to the landscape character, it is important to use varied housing densities in order to control the urban impact within Karaka. For our development proposals, we have chose a section of Karaka West that incorporates the different intensities of housing (high, medium, low), as well as the integration of ecological systems and permeable open spaces. The 60hA chosen site acts as a link between the industrial core and the proposed connection to Weymouth, adapting the main flow of traffic through the Karaka as an urban subdivision.

    Slope > 15

    SLOPE

    SCALE: 1:5000

    The slopes greater than 15 have been retired. These areas will not be a logical place to carry out urban development. However, from looking at the retired slope areas we can see that the focused extent is mainly flat surrounding Urquhart road, allowing for development across a majority of the area based on the GIS data collected. These slopes could however accommodate a number of vegetation species and be the basis for a re-vegetation scheme.

    River

    SCALE: 1:5000

    Within the focused extent only 2 streams intersect the site towards the edge. It is ideally logical to retire around these existing spaces as vegetation that is used to secure the steep banks. It is important to filter our systems naturally through vegetation so that Karaka as a sub-division will continue to promote the ethical water management.

    Flow Accumulation

    WATER FLOW

    SCALE: 1:5000

    The existing flow direction pattern shows run-off being discharged towards the east and west flanks of Urquhart Road. There is a greater impact of water run-off towards Northeast, East, Southwest and South because of the current topography of chosen site. Flow accumulation shows the collective zones as to where run-off is being stored in relation to the aspects of flow direction. It would be a logical idea to retire most of the surrounding land nearby the flow accumu-lation zones and potentially re-vegetate surroundings.

    WATERSHED AND BASIN

    SCALE: 1:5000

    A drainage basin is an extent or an area of land where surface water from rain and melting snow or ice converges to a single point, usually the exit of the basin, where the waters join another water-body, such as a river, lake, reservoir, estuary, wetland, sea, or ocean. There are 4 main drainage basins that exist within the focused extent. The edges of these basins construct a diagrammatic layout of the water shed. Run-off is not contained within the site and is dispersed towards the east and west.

    According to the aspect analysis of the chosen site, South, Southwest, West (247.5-292.5), Northwest (292.5-337.5) and North (337.5-360) are the most dominant throughout. Pockets of Flat, North (0-22.5), Northeast and East are spread adjacent to the rest of the classes. Usually north-facing houses get sun most of the day mainly at the front compared to south-facing houses. From an ecological perspective, north-facing houses are more energy efficient as well.

    VIEWSHED

    SCALE: 1:5000

    The views depicted from the GIS data were from a 2 meter level which is an approximate view from a human per-spective, and an optimum height of 10 meters from the peak of high density dwellings. It is clearly established most of Karaka can be viewed from a 10 meter height covering patches of landform. However from the 2 meter height mostly landform within the same horizon level or lower can be viewed.

    A 10 and 2 meter height view from the Medium density shows areas which can be viewed within the focused extent. The 2 meter height view is much restricted due to existing raised topography surrounding the marker, which is situated over a 23 meter high landform. Where as the 10 meter view within medium density also has a minimal restricted view.

    KEY

    Development of the location resides of high, medium and low densities, which integrate proposals of hydrology and vegetation to a sustainable design outcome. The high-density comprises of two 110 square meters housing approximately for apart-ment style living within a 630 square meter lots. The high-density housing is developed on an optimum scale of 3 stories apartment style living to house a high count of people. Between the high and medium-density zones are a number of retail for the residents to utilize. This was the ideal location to accommodate a small scaled retail due to the main core, located further down south consisting of large scaled retail and amenities to serve the residents of Karaka. Medium density contains 180 square meters of housing per 400 square meter lots. In the middle of medium and low-density is a potential for a development of schooling. This is located facing Urquhart road. The medium and high-density follow the Traditional Subdivision Pattern model and carry out its fundamental charact
