SITE ANALYSIS Sidney Meyer Asia Centre is designed to serve the needs of both University teaching and exhibition space and the headquarters of an education/ business group, Asialink. The building is located on the major entry axis to the University and will form the southern edge of a masterplanned principal entry forecourt.

DESIGN DRIVERS & INTENT Urban Facilities

Observations

-Slope suitable for natural drainage -Dead edge -Lack of thresholds -Lack of pedestrian ammenities

Design Drivers

DESIGN INTENT

-SUDs -Places of rest -Barrier to traffic -Ease of movement -Clear hierarchy of spaces -Integration with architecture of building

6

Activation through creating response to water drainage & planting to generate a sense of place.

Ammenities for socialisation & rest that co-exist with surroundings

Urban furnture that facilities moments of pause and directs movement.

SOCIABILITY

ESTABLISHING THRESHOLDS

FLEXIBILITY

INTIMACY

Better engagement between student and other user communities by interacting with landscape features

Creating better permeability between public and private space through blurring of spatial hierarchies

Social needs are met even with the lack of gathering spaces through areas of rest and retreat

Better interaction with Sidney Meyer as a pedestrian on Swanston Street establishing a sense of community and inclusiveness


PRECEDENT Merriman Square, Cape Town | Square one landscape architects A sustainable urban drainage system as the structuring elements for public place-making while facilitating convenient pedestrian movement. Rainwater is harvested from the roofs of the parking garage and stored in tanks to irrigate the expansive green faรงade. Overflow water is directed down the enormous support columns within the square and directed into vegetated bio-filtration basins. The basins sustain indigenous wetland species & recharge the water table which minimises the need for outdated storm-water infrastructure.

7


DESIGN CONCEPT Due to the nature of the large overhang - there’s potential to convert the space into sort of an ‘outdoor’ room - a intermediate space between the street and the building that can facilitate all types of movement/functions. Goal is to blur the harsh juxtaposition between the two types of spaces and create a more appealing

Transitional Spaces (The Outdoor Room) -Change in surfacing -Forms that can alter your pace -Level changes -Integration with building through materiality -Juxtaposition of materiality

Level change facilitates ergonomic flexibility - different ways of interacting with the space

Abrupt change in spatial experience due to the imposing cantilever - it immediately forms a very sudden sense of enclosure and one may feel reluctant to linger in the space for long.

-Open up the ‘outdoor room’ from feeling too enclosed (tucked away right under it) -instead use furniture and place it at the edge to draw people closer to the street

8


DESIGN CONCEPT Inspiration from Site

Directing Movement

The New Student Precinct (under construction) The chosen site is focused on the corner of Sidney Meyer and near the entrance of the new student precinct, this is also where a traffic light is found. There will be lots of foot traffic in this area and the design and direct movement and activate the eastern facade of Sidney Meyer better.

DESIGN CONCEPT Activities change due to varying heights

WSUDS AMBITION

‘The Water Carpet’ is designed to allow for visual connectivity whilst creating a sense of arrival and transition.

WSUDS AMBITION urban water sources & the site Water can be collected, retained and stored locally Creating Water Sensitive Streets • Storing all rain water locally, including peak events • A chance to upgrade and improve public space quality • Greening the district substantially • Creating a climate adaptive solution at the same time (cooling the stony urban fabric)

WSUDS AMBITION

the waterwall The wall can act as a means of street furniture and water storage and when at capacity, can create a water feature that enhances the qualities of the site. Water can be collected from the nearby roofs and canteliver and also be channeled from the street run-off to be cleansed in the raingarden. Any excess can be stored in the tank to be used as a feature.

13

water trough and water form


FOUNTAIN EXPERIMENT The implementation of the raingarden calls for the strategic channeling of rain runoff over surfaces. Because the project is also sited near a building, it will also receive roof run-off. Thus brought the opportunity to utilise the water to create a feature that would add an additional relaxing quality to the site. This project was a means to see if water can be pumped from the bottom of the tank to the top without a water pump but with the use of gravity. Thus a excess amount of water would be able to trigger the fountain to function.

Step 3

Step 1

Step 2

Heron’s Fountain is means of directing water movement through gravity and pressurised air. When water is entering the system, it will push water out of the system at the same rate. The experiment was to see if the fountain could potentially move in perpetual motion as water leaves the system and enters it again.

MATERIAL PALETTE The existing conditions of the site is dominated by concrete, asphalt and corten steel, which adds a very cold and harsh quality to the space. When strong shadows are casted over the site, the heavy aesthetic is emphasised even more. Thus, there is opportunity to introduce contrasting elements like timber, light pigmented surface and planting to balance out the feeling of heaviness and add a quality of lightness to the space. At the same time, the integration of materials such as corten steel and grey blustone pavers can also be used to bring a sense of unity with the rest of the existing context.

Corten steel is uniquely selfrusting, giving it a deep orange appearance. It is weather and rain resistant and needs very little maintenance once installed. It is also high strength, weldable structural steel which makes it ideal to form part of the supporting wall structure. At the same time it can balance the Corten sculpture on the facade on the northern side of Sidney Meyer. It does not require corrosion protective treatment, and although very long lasting, might need to be replaced at some stage for aesthetic purposes.

Bluestone paving is integral to the character of Melbourne CBD, it signifies a change in the ground plane where people are able to rest and reflect. Highly durable and suited to areas susceptible to changing weather conditions. The combination of dark blue, grey and charcoal hues creates a minimalist feel in the stone and gives a sleek contemporary finish without hindering surrounding garden environments.

The polished and white surface of white pigmented concrete creates a stark constrast from the existinig asphalt of the site, making wayfinding easy and directing movement in and around the site. It gives a sleek look, suitable for institutional and professional settings. Concrete pavers will rarely crack, shift or settle under normal foot or vehicle traffic, making them long lasting. They are also very easy to remove and replace.

Timber offers and additional quality of warmth to the site to contrast with the cold existing facade of Sidney Meyer. It invites passing pedestrians to site and take a moment. Hardwood is very easy to maintain and clean and extremely durable. It also comes in a variety of colours which can complement the surrounding greenery and the deep orange of corten steel.
