Individual project with assistance of Wurundjeri Elders Uncle Bill Nicholson and Uncle Dave Wandin

Bolin Bolin Billabong, Wurundjeri Country, Naarm (Melbourne), Kulin Nation

Bulleen VIC 3105

The design concept of the project is “Caring for water”.

The project aims to make Bolin Bolin Billabong and Birrarung River (Yarra River) healthier, to rekindle the riparian areas as an event space, and to celebrate the traditional plant knowledge of Wurundjeri culture. The concept is inspired by the Wurundjeri philosophies and traditional usage of the place. Woody wetlands will be built around the river and the billabong. The wetlands will provide a buffer to the waterbodies, collect and filter grey water and stormwater, provide cultural water, serve as Wurundjeri plant knowledge outdoor workshops, and provide event spaces.

In Wurundjeri culture, water is the lifeblood of the Country, therefore it is critical to care for the waterbodies. Humans were created by Bunjil to look after the Country in Wurundjeri Dreaming stories. Birrarung River and Bolin Bolin Billabong are two of the most sacred components of the Country. Therefore, it is humans’ duty to make the river and the billabong healthy.

Grassy lawns are around the site. They have the potential for ecological retrofits.

The billabong suffers from a lack of water, eutrophication and invasive species.

Birrarung River

Traditionally, Birrarung is seen as a living entity that can hear and has a spirit.

Kulin nation Wurundjeri Caring for Country

Birrarung is the heart of the Kulin nation, which consists of five language groups.

Wurundjeri people are the traditional owners of the site areas. Bolin Bolin Billabong is one of the most sacred sites for the Wurundjeri communities.

Kulin people believe it is the responsibility of humans to look after Country to keep the Country healthy.

Threats and management opportunities

Water is the lifeblood of Country

Country cannot stay healthy without a sufficient amount of clean water.

Encroaching urban development

Urban development may be built upon the parkland.

Mismanaged vegetation

Over-dense tree canopy covers decrease vunderstories’ biodiversity while being vulnerable to bushfires.

Urban stream syndrome

This includes flash increases in water volume linked to rain and low water quality.

Eutrophication of the billabongs

Bolin Bolin Billabong has accumulated too many nutrients washed down from the nearby residential areas.

Buffering

Grasslands

Constructed woody wetlands Bolin Bolin Billabong

A range of treatment wetlands will be built. The purified water will be utilized for ecological purposes.

The billabong will be restored to a healthier ecological state.

Bolin Billabong

Annulus Billabong

Annulus billabong will be used as a testing ground for ecological retrofits prior to the restoration of Bolin Bolin Billabong.

Buffering woodlands

The residential areas around Bolin Bolin Billabong will be purchased and revegetated.

Design strategies and management of the project

Design Opportunities

Cultural water Culturally and ecologically managed vegetations Reclaim of the residential areas

More water needs to be controlled by Wurundjeri communities to increase biodiversity.

Cultural burning will be re-introduced with indige nous vegetation plantations. Lands from the nearby areas will be gradually purchased by the government and turned into parklands.

Rekindle plant knowledge Community engagement

The plant usage and cultural meanings will be celebrated in the design.

The local communities will be educated and empowered to care for the ecosys tem.

The Unfolding Seasons 四季绵延

In Ancient China, Scholar Gardens are spiritual retreats from the stresses of the world. In the context of Naarm, the project aims to create a contemporary scholar garden with a multi-seasonal experience as one strolls through the site.

The project refers to the Scholar Garden ‘Geyuan’ which created four seasons through planting types, visual cues & abstracted metaphors. By merging these influences & adding an additional layer of the microclimate, ‘The Unfolding Seasons’ express the emphermial beauties of seasonality through the featuring of the current season & the subsequent season. The design creates microclimatic options for visitors & gestures them to revisit Chinatown in the next season.

Plants’ LegendsTraffic Design

The proposal intends to pedestrianize the site with car access during early hours for the unloading of goods. The road system will be rearranged with shared paths, which can be used for emergency vehicle access.

A.The traffic for cars exiting from carparks at Pender Place will be redirected to Market Lane.

B.The traffic flow of Market Lane will be reversed to facilitate vehicles’ exit.

C.The bicycle lanes will be built on the north of Little Bourke Street.

4. Shading Infrastructure

The windbreaks will resist the gale from the north while embracing the southern wind. To enhance a cooler microclimate of the Winter Garden, a windcatcher will be installed to capture and direct southern wind from the canopy level to the street level.

The shadow will be cast by different vegetation, which will create a cooler microclimate for Winter Garden and Autumn Garden.

3. User Inhabitation

2. Boundaries of the Four Following Seasons Gardens

The Seats will provide spaces for outdoor dining, while the stone hemispheres will allow visitors to lean on and warm up their bodies.

The design of the four following seasons garden will be based on the microclimate zoning, with unique design interventions.

1.Data-Driven Microclimate Zoning of the Site

Summer in Spring (Warmest microclimate in Spring)

Autumn in Summer (Coolest microclimate in Summer)

Winter in Autumn (Coolest microclimate in Autumn)

Spring in Winter (Warmest microclimate in Winter)

Areas with microclimates that most resemble the following season will be identified, with their microclimate features exaggerated through design interventions.

Microclimate infrastructures

1. Windcatcher

The structure will be built on the northern wall of the Winter Garden, to capture the desired southern wind and block off the Northern wind.

The Southern wind at canopy level will be diverted to Winter Garden to enhance a colder body sensory microclimate.

2. Windbreaks

The windbreaks will be consisted of dense vegetation to block gale at human height and guide the direction of the Northern Wind.

3. Microclimate Adaptable Seats

The seats will consist of timber benches which can be flipped up or down depending on user preference of microclimate.

Half of the timber on the benches can be flipped up to form the backrest or flipped down as a part of the bottom of the seats.

On hot days, users can flip up the timber benches to allow breezes to run through the benches.

Locations of Microclimate infrastructures

Spring in Winter 冬日之春

The Spring Garden (Wintertime) will have a warmer microclimate. Maximum solar exposure with mild wind is used to determine the location of Spring Garden. The microclimate in Spring Garden will be further enhanced with microclimate heating strategies.

Spring Garden in Winter

A. Solar gain

The deciduous species will be planted to allow solar exposure during winter to enhance a warmer microclimate. The area will function as a small square.

B.Thermal Seats

The Microclimate Adaptable Seats will have their timber backrest folded down during winter, to expose the concrete backrests to the sun. The concrete will absorb heat and warm up users’ bodies.

C. Paving Material

The pavers will be made of Percydale Cobblestone, which has the darkest colour on site. This dark colour enables the pavers to absorb heat and heat up the areas.

Summer in Spring

Summer Garden (Springtime) will have a warmer microclimate. Optimum solar ex posure with milder winds during spring is used to determine the location of Summer Garden. Microclimate interventions will further enhance the warmer microclimate in the Summer Garden to simulate a summer experience.

Summer Garden in Spring

Windbreaks will be planted to reduce the eastern wind while avoid shading the area. The windbreak will divide the space and form a spatial threshold.

B. Roads

The roads will subtly demarcate the car lane and the pedestrianized area with gen tle level changes and materiality differences.

C. Paving Material

The paving material for the Summer Garden in spring will be Harcourt Cobblestone, which is the second darkest stone on site. Harcourt Cobblestone with a moderate ability to absorb heat will enhance solar absorption without overheating the space.
