Designed by Australian architects Contreras Earl Architecture, with leading engineering and sustainability consultants Arup and Werner Sobek for the Great Barrier Reef Legacy, the primary goal of the Coral Biobank is to keep alive and nurture over 800 species of the world’s hard corals.
The new building typology “a living ark” will be the only dedicated facility of its kind in the world. Through its innovative design and engineering, it will be a world leader in next-generation renewable energy design, creating optimal conditions for coral storage while minimising energy consumption and solar gain.
“The Living Coral Biobank is the only project that can secure the living biodiversity of the world’s coral species immediately,” says Dr Dean Miller, Living Coral Biobank Project Director and Managing Director of Great Barrier Reef Legacy.
Rafael Contreras said “this project brings with it a profound responsibility to consider the impact of architecture and the construction industry on the natural world. As one of the world’s major contributors of CO2 emissions and associated climate change, it is essential that the construction industry be encouraged by architects towards carbon neutrality. The Living Coral Biobank is an opportunity to set a global benchmark for sustainable outcomes and zero-carbon goals as well as creating a world-leading conservation and education facility. The ambition for this project is to create a beacon for environmental awareness – a centre of hope, learning and wonder.”
While the corals will be the primary building user, the 6,830 sqm multi-function centre will also host exhibition areas, an auditorium and classrooms as well as advanced research and laboratory facilities over four levels. Providing an important education resource for Port Douglas, the wider region and specialists worldwide, the Living Coral Biobank will enable visitors to get up close to live specimens in aquarium displays, learn about coral ecosystems through exhibitions and events, and observe coral husbandry experts going about their daily work in a protected wet lab environment. In addition, the facility will also have a unique 200-person function space.
The building’s sculptural form is inspired by the ‘mushroom’ coral – a hard coral identified by distinctive protective radial fins. The Living Coral Biobank’s facade is conceived as a series of organic undulating concrete fins clustered closely at ground level to offer protection from adverse tropical conditions including threats of flood. As they progress upwards the fins twist and unfurl, allowing natural light and ventilation of the upper levels while providing solar shading. The fins pull apart progressively towards Level 4 to provide a culminating visitor experience of a naturally-lit exhibition and education space.
The morphology also responds to the need to conserve the corals at lower building levels in a highly controlled environment as well as the requirement for biosecurity to prevent cross-contamination. Contreras Earl Architecture is collaborating with Arup and Werner Sobek to integrate a holistic sustainable strategy that reduces energy consumption by tactically dividing the building into six compatible climate zones over four levels, with adjacencies minimising energy resource use for climatic control. Aspiring to the biosystems of the coral reefs themselves, the building will aim to be self-sufficient and carbon-neutral.
Architectural manipulation of light plays a significant role in defining the visitor journey. The experience begins at the entry plaza – a terraced forum space, providing transition space from the humid tropical heat of surrounding landscaped gardens and continues via a grand stair to the Level 2 Central Viewing Platform, from where visitors can observe the wet lab specimen tanks in a protected environment below.
Public spaces across the building’s main levels are visually connected through a central atrium, with the illumination generating a surreal atmosphere through the building’s levels much like the depths of the sea. At lower levels brightness and colour is introduced through reflections from the wet lab tanks, while cool light emanates from aquarium tanks positioned on Level 3. The fluorescence of the corals also contributes to the experience. Guests attending evening events and conferences will be surrounded by glowing coral species in the only function space of its kind.
The Living Coral Biobank resonates with Contreras Earl Architecture’s belief that sustainability should inform every design decision – from concept through to the choice of materials and details and onwards to construction processes. The design strives to emulate the exactness of nature where nothing is random but every characteristic has a specific purpose. It is responsive to context, climate, the user and its function to protect 800 species of coral.

The Project Team
Architect / Contreras Earl Architecture
Rafael Contreras and Monica Earl combine their unique cultural perspectives and international expertise in a boundary-pushing multi-disciplinary practice based in Australia. Together, with a team of international and local collaborators, we challenge conventional thinking in design, materials, construction processes and city- making. We look to biological systems and nature’s complex structural patterns, learning from their blueprints to forge new architectural ground. Our aim is to contribute to the evolution of architecture and our design process is driven by the careful analysis of contemporary life and the desire to create buildings that coexist with the built and natural environment. By using advanced technologies, we are liberated from traditional building practices and forms and free to explore ideas that respond to the era where we live in order to create a better future for our urban and natural environment.
Client / Great Barrier Reef Legacy
Based in Port Douglas the Great Barrier Reef Legacy is a global leader in marine conservation, accelerating actions vital to the future survival of coral reefs. It was formed by a dedicated team of professionals in marine science, conservation, tourism, education, and multi-media to address the urgent need to ensure the long- term preservation of the Great Barrier Reef. After only four years of operation, Great Barrier Reef Legacy has a proven track record of delivering positive and cost-effective outcomes for the Reef and community including marine research and tourism expeditions, innovative citizen science and world-class documentaries, supporting research projects from major universities and government organisations and providing solutions for educators and the global community to rapidly act on climate-related issues for coral reefs. It is a not-for- profit charity, holding Australian and United States Tax Deductible status. It has raised over $1 million dollars through public, private and corporate funding.
