Hello!

My name is Chanika, and I am an Australian-Sri Lankan from Sydney. This mixed background has fuelled my interest in cultural and political architectural design. Hence, I am passionate about design that is accessible to everybody and is a positive social intervention. I love good design.

UNMUTESTUDENTEXHIBITION

A SMALL HOME IN ASHFIELD

A family of four need an extension of their small home in Ashfield. They requested increased internal sunlight and improved connection to the backyard. This design addresses their needs and complies with the Ashfield LEP 2013 and Inner West DCP. A DA form was prepared.

CONNECTION TO THE LANDSCAPE

The home honours the “Shakkei” concept of burrowed scenery. Thus, the Engawa (Japanese verandah) is the central axis that connects the cleint to the backyard garden regardless of their location inside. The Engawa’s outer edge has partially glazed timber sliding louvres and the inner edge has sliding doors; enabling views and internal climate control. Moreover, the Engawa allows cool north-easterly summer winds to circulate. The garden is has native and Japanese plants, aligning with Skakkei and the Australian context.

BARANGAROO RESERVE TOWER

The brief is to design a 4 m x 8 m x 12 m tower in a significant location of choice. Differences in materials, construction methodology, and structural typology are to evoke an emotional and sensory experience as one transitions upwards and descends back down.

DESIGN FOCUS AND CONSTRUCTION

The Tower utilises views and sunlight to define the spatial transition between floors, enhanced by materials and construction. The lower two levels have in-situ concrete walls that slope upwards to create melancholic mood that gradually dissapates as one traverses up; a lightness from the progressively larger windows. This shift is reinforced by the change from heavy to floating steps. The final floor walls are light autoclaved aerated concrete (AAC) and galvanised steel frames. The exposed walls and vista views cultivates hope within.

SPATIAL TRANSITION BETWEEN FLOORS

GROUND FLOOR

IN-SITU CONCRETE WALL CONSTRUCTION

Interior formwork of timber studs first support the exterior formwork, creating a smooth external facade.

Concrete is filled in-situ and in layered intervals for the concrete to set properly and maintain strength.

The interior and exterior formwork are then removed, leaving a smooth facade and ribbed interior walls.

Finally, a smooth wavy pattern is manually bush-hammered along the interior ribs.*

UNMUTE STUDENT EXHIBITION

‘Unmute’ celebrates the return to an on-campus study of architecture, and students’ work. Students are now unmuting themselves and are hands-on.

Turning to our old friend trace for its palette, the exhibition’s materials were reused by students for their projects that semester. Trace is an invitation to experiment, a canvas for collaboration, and a promise of iterative progress.

Key contributions: exhibition designer, producer, installation technician, furniture designer and panel graphical designer.

DESIGN THINKING AND DEVELOPMENT

The first iteration of panel graphics resembled sound (i.e. UNMUTE), however, it was hard to uniqely transfer onto all the panels. Thus, thinking about the ebbs and flows of design, the final graphic was inspired by sound waves. I designed seven versions of dynamic waves that can be individually stretched and adjusted across the panels. Moveover, we staggered the panels follow the flow narrative. We also recived limited submissions, so we created dummy panels out of baking paper between each submission panel and fill up space.

MARKETING AND VISITOR ENGAGEMENT

Promotion for UNMUTE was primarily through word-of-mouth and complimentary exhibition guides. However, our closing night was promoted through posters throughout the Archtecture Design and Planning (ADP) Faculty and on their Instagram page - to great success! Post-exhibition, we put the baking paper into a dispensary for students to use, continuing the functionality and legacy of UNMUTE. UNMUTE was the first student-led exhibition in the ADP Faculty. The exhibition has inspired many student-led campus exhibitions.
