Site Context Precedents Site Qualities

Prior to commencing the design process, if was necessary to look at a numberof successful waterfront precedents. The four which I looked at in the closestdetail include;

- Pirrama Park (Sydney)- Barangaroo (Sydney)- East Perth- West 8 (Amsterdam)

All of these sites are great examples of how clever design has re-establishedthat crucial link between the land and the water, a design principle which wouldbe very important at Fletcher’s Slip.

Each site also has a varying use based on its surroundings, for example

Pirrama Park which works as a public park, East Perth which functions as amixed use space and West 8 which is purely residential. These three uses arewhat I intend to introduce to the Fletcher’s Slip site.

It is very important to consider the broader context of a site before coming upwith a design. Looking at the location of Fletcher’s Slip, there appear to bethree main issues which relate closely to the site

- Zoning (mixed between Commercial and Residential)- Close Proximity to Semaphore- Lack of public open space in t he general area.

In order to create a successful project, it is necessary to address theseexternal impacts. Given the site is situated amongst a mixtur e of Commercialand Residential space, it is only logical to continue this same type of usageon the site.

The site’s close proximity to Semaphore is also substantial in the sense that

both sides may be competing for visitor numbers. It is therefore necessaryto create a design which offers visitors a different experience to Semaphore.Perhaps, the two sites could even be linked using the Commercial samewhich links them along Semaphore Road.

As these images show, the Fletcher’s Slip site has many distinctive sitequalities. Those which are most apparent to me include;

- Close proximity to water’s edge- Historical context- Decay- Pre-existing Architecture- Range of existing materiality- Proximity to Port Adelaide, Semaphore- Views (to Hart’s Mill, Hills etc.)- Open Space

Each of these qualities provide a great opportunity when redeveloping thissite.

VISION

04

The redevelopment of the Fletcher’sSlip site at Port Adelaide offers a very

exciting opportunity to rejuvenateand reinvent one of the most beautifuland underused sites in Adelaide.

Fletcher’s Slip was once usedas a shipping slip where visitingships would receive any repairsor maintenance that was requiredafter their long journey to South Australia. Changing t rade practiceshowever made the site redundant,and since the site was effectively

abandoned in the 1980s, it has beenleft to decay and weather. Decay isa process which is occurring almost

everywhere at Fletcher’s Slip. Theconcrete is cracking, the timberis weathering, the steel is rustingand the vegetation is growingout of control. It is currently a sitecompletely run by mother nature.

The portrayal of decay in landscapearchitecture is almost unequivocallynegative, however, would it bepossible to create a design whichbrings out the positive aspectsof decay? A site which uses thisnaturally applied ‘nish’ to enhancethe quality and feel of a design.

It is this principle of using decayto enhance which has driven thisdesign, entitled ‘Tides’.

Decay in landscape architectureessentially comes down to three

things; change in shape, colourand condition. ‘Tides’, as its namesuggests, achieves these threeinuences by using the varying oceantides to change the site throughoutthe day. As the tides come in andout, the shape, colour and conditionof the site are forever changing,replicating the natural process ofdecay. At certain times of the day,some parts of the site are inundatedand at others they are dry, creating

a variable atmosphere throughoutthe site. The tides will also bringin natural marine vegetation such

as marine algae which will covermany parts of the site, displaying t henotion of mother nature applying itsown ‘nish’ to the site.

From a planning perspective, thesite will be separated into threemain precincts, which include aCommercial/Mixed Use Precinct, anOpen Pace Precinct and a ResidentialPrecinct. It is the inclusion of thesethree site uses which will mean that‘Tides’ caters for all members ofthe local community, and becomeone of the most exciting and vibrant

locations in Greater Adelaide.



Given the amount of decay which is currently occurring on the Fletcher’s Slipsite, it is only natural that a new design would embrace this site quality.

This design therefore seeks to emulate and enhance the natural decay whichis already occurring on throughout the site. Using a series of level changes,the site will constantly evolve as the tides come in and out, changing the

shape, colour and condition of the site. Special material and plantingpalettes will also be carefully selected in order to replicate the process ofdecay throughout the terrestrial areas of the design.

The design principle of rectilinearity is inspired by the site’s former usage asa shipping slip. Given that the site was purely used for the purpose of gettingas many ships in and out as quickly as possible, the site ended up being littlemore than a series of parallel slips and sheds, all facing directly to the water’sedge.

It is this presence of linear and rectangular forms throughout the former site,along with the intention of creating vistas facing the water which have been aparticular driving force for this design.

The nal design principle relates to Environmental sustainability. This will beachieved using numerous green infrastructure initiatives throughout the site,such as bio-retention swales and water tanks which will effectively be used toirrigate all on site vegetation.

A strong planting palette consisting entirely of drought tolerant indigenousspecies will also be used throughout the site in order to reduce the need forexcess irrigation during the dryer months.

This design is primarily focussed on pedestrianmovement, with vehicle and bicycle movementgenerally being directed around the site.

One exception to this policy occurs in the residentialprecinct, which uses shared ‘One Way’ streets inorder to provide vehicle and service access to allapartments.

MOVING LANDSCAPES

17

One of the design’s most intriguing features willbe two ‘moving landscape’ platforms. The rstlandscape platform (left) will effectively use one ofthe site’s old shipping slips, and will come in andout of the site as the tide rises and falls. This shiftin position will include both vertical and horizontalmovement and will constantly change howvisitors to the platform perceive the surroundingenvironment.

The second moving landscape platform (right) willremain in the same position horizontally, however

will move vertically based on the t ides. The platformwill effectively have a constant level in relation tothe water, but will be constantly shifting upwardsand downwards in relation to the site.

The design will feature numerous marine gardensthroughout. These gardens will primarily feature Australian mangroves, but will also include variousnative salt marsh species.

Over time, it is also hoped that a certain amount of

marine algae will also blanket parts of the site.



TIDAL IMPACT

PHASE 1

Low tide

PHASE 2

Medium tide - Water begins to ow into the site

PHASE 3

High tide - Water reaches maximum level

PHASE 4

High tide - Over time, algae is deposited on site

PHASE 5

Medium tide - Algae deposited at high t ide remains on site

PHASE 6

Low tide - Water drawn out of site, leaving algae and seaweed deposits

Given one of the main design principles of the design relatesto using decay to enhance, materials have been selected

based on how they will decay over time and how this may beused as a positive design feature.

A blend of corten steel and existing recycled steel from the sitewill be used throughout the design, due to their ability to rust ina desirable fashion, displaying nature’s ‘nish’ to the site.

EXPERIMENTAL MODEL

This experimental features a few concrete steps,simpler to what would be used on the site.

The experiment was conducted by placing theconcrete model into a container lled with saltwater containing an abundance of marine algae.The container was then placed into the sun, in anattempt to see if the algae would grow and attachto the concrete.

It was hoped that this plus natural evaporationwould lead to the creation of a model which wouldbe comparatively clean at the top and covered withalgae at the bottom, replicating onsite conditions.

Here are the results...

PHYSICAL MODEL

The nal step of the process involved creating aphysical model of the whole design. Viewing thismodel allows one to see how the site functions,

and how the three main precincts, as well as thetwo moving landscapes, relate to each other andthe rest of the site.

The model also gives viewers a great perspectiveregarding how the design interacts with the water ’sedge, both along the canals through the site andalong the harbour frontage.

The verticality of the model has been exaggeratedon a scale of 3:1, in order to make the depth stand

out to the viewer.
