The project site – Kronos Hills and Wentworth Commons (part of the Sydney Olympic Precinct), totalling 40 ha in size and containing remediated landfills, freshwater wetlands, frog ponds and underpasses, provides a primary habitat for the endangered Green and Golden Bell Frogs and numerous water-birds and insect-eating bird species. With its large open recreational spaces, it provides ample facilities for public leisure and play activities. The site is affected by primary issues like destruction of natural reserves, existing freshwater wetlands and ecosystems due to rising sea levels from increasing rainfall averages. Freshwater sources will be impacted by the subsequent increase in salinity. Furthermore, as sea level rises, the disruption to the remediated lands will exacerbate leachate and acid sulphide leakages into water-bodies. Besides this, there is an increasing demand for human access from visitors and fast developing neighbourhoods putting the current amenities under high duress. Our proposal develops the site as an environmental preservation and education zone highlighting water management strategies for the current times and the predicted future. Explorations into existing systems of extracting freshwater from seawater led to an innovative adaptation of a biophilic system seen in Mangrove roots and leaves, the Reverse Osmosis process, applied within an architectural system that can aggregate over time. Freshwater being the primary product with the by-product of concentrated salt water utilised in farming salt on the architectural structure. The farmed salt is reused in constructing/growing this architectural structure over time. Our explorations into salt as a raw construction material have revealed strategies providing potential methods to construct on difficult terrain, as well as a unique natural shading device that builds over time. As the sea level rises, the structures develop providing growing supply of freshwater and habitats for local fauna, within a continuous sustainable loop of farming salt and aggregating the pods as required. These structures can be designed to offer various amenities to the booming local communities. Existing amenities under stress, with the possibility of disappearing as sea level rises, can be reinstated through the aggregation of these structures. The discovery centre will be the first introduction of this proposal for this site. It will offer unique experiences for visitors, in the form of interactive installations with salt water, climbing structures, leisure and café areas overlooking freshwater ponds. Furthermore, educating visitors about water management strategies, and offering guided bike tours along Haslams creek. Site development aims to address and meet the key targets for the UN sustainability goals of Clean Water & Sanitation, Life below Water and Affordable and Clean Energy. To assist in the concept development, two rule-based scripts have been generated to address the requirements of reverse osmosis system – firstly to provide minimal surfaces with parameters of variable enclosed volumes and slopes necessary for inducing the required pressures, and secondly networks of minimal points and lines on surfaces with related density, extent, and offset parameters to induce different efficiencies of filtration. By 2100, these pods will have been scattered across the flooded land connected by new bike paths offering the locals new leisure amenities and freshwater supply whilst introducing growing habitats for the now endangered flora and fauna species. 3 l Page

2.4 SITE OPPORTUNITIES
SEA LEVEL RISE + INCREASE IN SALINITY
PEOPLE - EXISTING CONDITION
• The predicted extreme sea rise of 1.25m by 2100 will cause destruction of the nature reserves, flora and fauna habitats, and existing Nuwi Wetlands. Fresh water sources will be impacted by the subsequent increase in salt.
• Increase in demand for human access as local population booms. Current amenities are under stress and the lack of site connectivity is causing overcrowding at certain points whereas other sites like the natural reserves are being under utilised.

3.2 BIOPHILIC CASE STUDY - MANGROVES
3.3 ARCHITECTURAL CASE STUDY - FLOATING DESALINATION STRUCTURE
• Mangroves utilise natural osmosis process of salt separation through filter layers in roots and leaves. Through pressure fresh water is extracted and salt is flushed away. • Mangrove roots extract the freshwater which is stored and circulated through the central vessels. The air-pathways/filter layers gather the salt and flush it through the leaves. • Mangrove leaves farm the salt on the surface. Once enough salt has built up over time, the weight causes the leaf to fall, thereby getting rid of the salt with a growth of new leaves.
• A concept exploration of desalination system applied into an architectural scheme in Chicago. • Traditional heat desalination components readdressed into an architectural form. The system works by pumping salt water into an elevated pond. Through solar power heat is generated to boil the water. The dome covering the pond collects the evaporation and feeds the freshwater into water tanks to be used for agriculture. The architecture hosts and operates the system whilst being utilised for other human centric functions. • Designed as pods/modules that can be aggregated across the site as needed with a simple connection/bridge in between.

3.4 REVERSE OSMOSIS PROCESS
3.5 CONCEPT ADAPTATION AND SCRIPT BASE RULES
• Reverse Osmosis - a system of extracting fresh water from salt water without heat. Instead pressure is used hence making it a more efficient and sustainable approach. • Reverse Osmosis works by using a high pressure pump to increase the pressure on the salt side of the RO and force the water across the semi-permeable RO membrane, leaving almost all (around 95% to 99%) of dissolved salts behind in the reject stream. The amount of pressure required depends on the salt concentration of the feed water. The more concentrated the feed water, the more pressure is required to overcome the osmotic pressure.
• Reverse Osmosis key components translated to site with initial form ideas that address the requirements of the system through our rule-based systems. • Requirement 1 (Script 01) - variable slopes to allow gravity assisted pump pressure (Number 3) • Requirement 2 (Script 01) - variable enclosed spaces to host services (pumps), water storage (freshwater ponds) and water media filter tanks (Number 2) • Requirement 3 (Script 02) - variable filtration piping structures with density, extents and offset variations to induce different efficiencies in filtration as needed

4.2 SCRIPT 01 - STEREOTOMIC CASE STUDIES
4.3 SCRIPT 02 - TECTONIC CASE STUDIES
The Tectonic script was majority inspired from spider webs and urban element on site like the climbing frame. Frei Otto’s works, which explores optimised path systems, using threads to establish networks of minimal pathways were looked into. This highlights the ways in which form-finding can occur through natural self-organising systems and point and line networks.
Works of Vlad Tenu “ Synthetic nature” and Eva Hild’s ceramic sculptures were the inspiration for the stereotomic form. Vlad Tenu’s “Synthetic Nature” is a collection of prototypes which is a genesis of form and space. It involves nature inspired algorithms and geometrical constraints focussed on minimal surfaces.

They are typically multidimensional symmetric, repetitive and infinitely expandable. Eva Hild’s ceramic works in general are delicate continuously flowing entities meandering closed movements.

SCRIPT 01 - INITIAL CONCEPT RENDERS 3D VIEW 01
Minimal surfaces are those that have a minimal total surface area given the volume. The most common example of minimal surface is soap bubble formed between one or more loops. The base unit selected for initial form exploration was the Schoen’s Batwing minimal surface. Minimal surfaces are symmetric along at least two planes. Hence modelling one surface and mirroring it along the required plane can give us the final minimal surface form. They can also be modelled using simple geometry in a cube.

The base unit for form exploration built in a cube, with control points based on one face of the cube. Since base form is built by mirroring one single surface (made on one of the cube’s faces) along radial planes, changing any parameter will result in uniform change throughout.

SCRIPT 02 - INITIAL CONCEPT RENDERS Initial script explorations looked into integrating the filtration pipes as an elevated canopy surface structure that can filter nearby sea water into a freshwater supply to the existing frog ponds. The surface can then have solar panel inserts to power the osmosis process services. The key parameters are the surface point and line connection network types with density and spread variables for different filtration efficiencies. The frame offset parameters based on points/surfaces allows for creating climbing structures and potential volumes for fauna or people habitation at different scales.

POINT AND LINE NETWORKS (DENSITY AND SPREAD)
• Process - Pick safe anchor points from site model. Generate surface between points to populate with points (pattern as a parameter). Organize points in a regular pattern (parameter of offsets of different shapes) around key site points like frog ponds and trees. Elevating each point according to varied z value (parameter based on attractors and distance or graph mapper). Generate a mesh between points (Weaverbird plug-in) and using Kangaroo 2 Physics engine to stretch the mesh according to anchor points inputs creating different densities and spread as the surface is stretched.

4.6 PHASE 2 - MERGING SCRIPTS Type 1
Layers of the building form
This merging system involves Script 2 or the spider the network to act as a supporting structural frame to host the voluminous and spacious form derived from minimal surfaces. Apart from acting as a structural member for the form, it hosts the pipes of the water filtration system. Salt is sprayed onto the minimal surface shell, which could be made of an elastic membrane, from a distance, from the pipes hosted on tectonic network. Salt sprayed gives a diffused and evenly finish to the shell.
Type 2 Unlike type one, where one script is developed within another, type 2 is simpler in nature. The tectonic network still acts as a structurally supporting framework for the stereotomic system, which hosts the salt water filtration tank. Unlike type 1, there is formation of salt as the process occurs.
The homogeneous type of merging scripts looks at developing one script over another, making one completely dependent on the other. This gives us the opportunity to merge the two scripts into one completely. This also provides us with an opportunity of optimising the interior spaces (of stereotomic system) by controlling the parameters of tectonic system, which is developed over the other, in an efficient manner.

4.8 SCRIPT 02 - PHASE 2 EXPLORATION Script 2 acts as a patterning script with a potential to form either regular or irregular network with surface points
A denser pattern can be derived by using an attractor point on the surface. The density, extent of network and position of network on a surface can be parametrically controlled.
The corresponding image shows a relatively(from the previous two images) denser network.
A jittered network in perpendicular direction can be derived by offsetting the parent surface. The minimal surface form explored in Phase 2 is the Primitive minimal surface or the Schwarz P. This can be constructed using three circles along three different axis. Equal length of corresponding arcs on the circles are connected with a longer arc. A surface can now be made with a parametrically controllable center point which gives the dip, defining the overall volume of the form.
Page l 28
This single surface is them mirrored on 4 planes, to form the complete primitive minimal surface. Parameters such as openings, length of each of the spouts with openings, dip of one single surface and the longer arc which again controls the volume of the overall form can be controlled individually.

Curves from site, along which building modules can be designed were identified. Points on curves dictate the position of form modules.

Step 2 The cut unit is now multiplied thrice to form three different blocks (dictated by the function of the building).

Step 3 This step involves laying out options of arrangement of the three blocks on site. The selected one being Option 1, where the three blocks are positioned to open out to each other. The Entertainment block is positioned to be seen from main access road, giving it a scope to attract people in. While the Education block is positioned behind Entry block, for easy service and bike access. Entry Building positioned at the end of existing Haslams Pier.

Step 5 Scaling of the building modules according to importance, functional needs and surrounding context. The Entertainment and Education blocks are designed to be higher than Entry block, to not tower over the Pyramid hill. Volumes of the blocks dictate what the users perceive from different points on site, apart from catering to the functional needs. Entertainment block is designed with lesser volume. The tall and slender form combined with shorter, wider and bulkier Entry block reduce the overall scale of the three combined building block, when observed from Olympic Boulevard. When observed from a shorter distance, the Education block which would seem massive due to the height and volume, make the overall building seem massive, adding surprise factor for the users entering through existing Haslams Pier. 31 l Page

Step 6 This step is uses findings from the previous steps to derive the final form of the three individual blocks by trimming and merging two or more of the basic units from step 1.
Step 8 and 9 All the surfaces of the building blocks host the tectonic surface networks. The multiple layers give the script to form variations of the network. When physically observed, these surface after application of script, provide an interesting ambience indoor. They imitate the forest, creating a Komorebi effect ( light trickling through foliage).Highlighted surfaces of the blocks were layered and the layers were chiselled at places that didn’t require multiple layers functionally. These layers again host the tectonic network.

OVERALL CONCEPT PLAN • Our site will be developed as an environmental preservation, research and education precinct providing nature walking/ bike trails (RED) connecting the site and leisure amenities, with prominent access links to local developing neighbourhoods (green links) and the Sydney Olympic Park precinct through the Olympic Boulevard.
• Development proposed in three stages Stage 1 - Discovery Centre Zone - First introduction of architecture structure pods/modules and reverse osmosis system on site with new elevated freshwater pond/habitat. It will offer unique experiences for visitors, in the form of interactive installations with salt water, climbing structures, leisure and café areas overlooking the freshwater ponds. However, its main purpose will be to educate visitors about water management strategies and its advancements through installations and info panels, as well as offering bike hires with guided bike tours along Haslams creek. Stage 2 - Research Centre Zone - The base architectural module will be adapted to enclose a flora and fauna habitat research and preservation. Located at the existing salt marsh and mangrove nature reserves with man-made frog ponds, the structures will be elevated and are imagined to host larger freshwater pond habitats for research into freshwater ecosystems. Additionally the by-product of incorporated reverse osmosis systems, salt through farming, can be further explored for potential applications in wider construction. Stage 3 - Leisure Zone - The existing amenities are under threat of being disrupted by the sea level rise. As the last stage, once the sea level begins to impact the existing amenities closer to the wharf, our structures can be introduced with control as an extension providing the amenities needed at the time or reintroducing any lost amenities under water. • Our proposal will highlight Stage 1 - Discovery Centre Zone and how the later stages can be introduced through our developed strategies as applied in stage 1.

5.6 MATERIAL STUDIES - SALT SALT AS A RAW MATERIAL - BY-PRODUCT OF REVERSE OSMOSIS PROCESS • Current explorations into salt through farming as a construction material have revealed very positive opportunities for the architectural community. • Construction strategies in exploration currently are 3d printing, baking and heat compression, and methods of salt crystallization on surfaces. • Each strategy provides certain benefits in strength, thermal and water resistant properties, and provide unique light transmission and reflection properties and various surface textures.
SALT STRATEGY 1 - STRUCTURAL • The process of 3d printing and manually compressed and baked blocks/panels provides a self-supporting structural construction system. These processes provide additional benefits: • Compressive Strength - stronger properties then rammed earth walls. Allows for supporting larger load capacities. • Waterproof - compressing and baking process results in a finish to the block/panel (the texture can be rough or smooth) that offers water-resistant properties increasing the life-cycle of the material with the potential to build on submerged terrain.

SALT STRATEGY 2 - SALT FARMING / ARCHITECTURAL SHADING
5.7 MATERIAL APPLICATION CONCEPT
• Salt Crystallization process is always undertaken on a surface (preferably tightly meshed surface - fabric, metal etc) over a period of time. There are 2 methods applied in crystallization - through solar access (experiment 1) or submerged underwater (experiment 2).
• The base form designed as a structure with a central axis core and bulging out in the center, lends to certain applicable salt strategies. • The base of the structure, landing in freshwater wetlands and required to take maximum load, is made up of four precast panels (utilising strategy 1 - manually compressed and baked panels/blocks) transported to site and connected to form a self-supporting structure. • The floors and ramps, needing to be lightweight yet strong enough to support live loads and facade shell loads, utilise strategy 1 - industrial 3d printing process. • The facade shell made up of piping frameworks and panel insets utilise strategy 2 - solar induced crystallization on the detachable fabric panel insets within the framework for salt farming.
This process provides architectural benefits in design: • Opportunities for salt farming • Potential unique architectural shading device - surfaces can utilise solar method to shade areas depending on salt water mist density on the surface and its orientation to the sun path. • Various surface texture depending on time and salt build up.

FLOORS AND RAMPS STRATEGY 1 3d Printing with Robots and base scaffolding
• Each surface is designed as a kit of parts - filtration pipe with connection joints. Within the assembled piping framework surface, detachable fabric panels for farming salt are connected (these panels are applied according to shading requirements for the relative functions, and the surfaces orientation to the sun paths). • The piping cross-section explains how the inner filtration cavities function and how salt farming can be achieved based on the traditional industrial piping used in the reverse osmosis process. The outermost cavity containing the salt water flow is crucial in its position, it introduces an innovative feature when adapted into the architectural design of the proposal allowing to spray the salt water as a mist through the nozzles onto the attached fabric panels (salt farming). • Unique architectural shading device - where the detachable fabric panels are installed on the surfaces, the salt will aggregate over time depending on the factors such as solar exposure, humidity and temperature providing the management means to automate the infrastructures internal climate through control over the nozzles spraying the salt water mist on the fabric panels. The aggregation will enable different daylight transmission through the surfaces over time. • Salt farming - recycling farmed salt from the detachable fabric panels to be used in the construction of module aggregates.

5.9 TIMELINE STRUCTURE AGGREGATION Aggregation through a sustainable feedback loop process of salt farming using salt as a recyclable raw material for construction. Specifically applied in creating the base precast panels and in the salt paste/mixture utilised in the 3d printing process. As the pods aggregates, the structures can evolve to address different functions and accommodate various base forms to suit different terrain (slope) conditions.
2100+ Through further aggregation across the site as sea levels have begun to impact the neighbouring suburbs, the pods can address the restablishment as well as the required expansion of the amenities needed by the built up residential neighbourhoods such as Newingtion for providing community services.
Page l 48
2050 As sea level rises, the existing freshwater wetlands will be submerged. The pods can aggregate over this site, introducing elevated freshwater ponds using the sea water below, thereby replenishing the lost freshwater supply for both human-centric uses and freshwater pond habitats for the endangered flora and fauna.
CURRENT The Discovery Centre proposal will introduce the first elevated freshwater pond over the existing freshwater wetland. The pond will act as an additional habitat for the local fauna of the wetlands as well as an additional source of freshwater supply to monitor the wetlands freshwater levels for maintaining the existing ecosystem of the wetlands flora and fauna.
