Cairns Botanic Gardens by Charles Wright Architects

This mirror-clad visitor centre by Australian firm Charles Wright Architects was designed to be invisible amongst the surrounding trees of the Cairns Botanic Gardens in Queensland. Comprising two buildings and a dividing promenade, the visitor centre was designed as a gateway to the gardens, which contain a selection of tropical plants from northern Australian rainforests as well as from across Southeast Asia. Charles Wright Architects drew inspiration from the suit worn by the alien-hunter in the 1987 movie Predator to give both buildings a reflective outer coating that would play down their impact on the park landscape. "We proposed a design which literally reflects the gardens as camouflage for the building," explain the architects. Rather than cover the surfaces with a single polished plane of metal, the architects added a series of flat panels that break the facade down into facets. Each one sits at an incrementally different angle and helps to muddle the reflected images.Charles Wright Architects have offices in Melbourne and Shanghai. 

Here's a project description from Charles Wright Architects:

Conceptual framework

We set-out to design a "green" building which represents a paradigm shift for Cairns, moving away from the conventional building vernaculars toward new and progressive solutions that can be applied anywhere on a tropical latitude. There was a collective desire to attract both national and international attention, which would also aid in creating new opportunities and connections to existing facilities, communities and groups.

Public and cultural benefits

A new, iconic gateway into the botanic gardens and tanks arts centre precinct – "a democratic public space under-cover" – a challenging new architecture for the tropics which will act as an attractor to assist Cairns in its mission to be seen as a progressive city nationally and globally significant.

Relationship of built form to context

Council called for the building to be long, low and blending seamlessly with the surrounding environment (ideally invisible). We proposed a design which literally reflects the gardens as camouflage for the building with visual effect similar to the suit as worn by the alien hunter in the original 1987 Predator film. We sited the new building to straddle and activate the pedestrian promenade linking the gardens with the Arts Centre, acting as an open and flexible conduit into the interpretive and performative spaces.

Integration of allied disciplines

The project team had a collective desire to develop a world-class ESD, flexible office and mixed use public facility which wasn’t reliant on complex technological solutions or costly maintenance. We collaborated closely with council's public artist to incorporate art glass within the glazed promenade facades.

Sustainability

ESD initiatives include solar panels for feedback into the energy grid, stormwater harvesting tanks, mixed mode air-conditioning systems, low energy light fittings throughout, low water usage fittings, long life cycle efficiency materials and construction, solar treatment to all windows, naturally ventilated circulation corridors and shaded exposed thermal mass internally.
