DESCRIPTION:

When the Metro Toronto Zoo opened in 1975, a new philosophy about what zoos were and how they functioned was part of the discussion
that, in turn, resulted in the radical new design of the various pavilions. These included the African and Malaysian pavilions.



The design of the buildings was carried out by a consortium of firms, Clifford Lawrie Bolton Ritchie Architects, Crang and Boake Architects,
Ron Thom Architect, and Yolles Engineers. Part of the intention behind the design was to separate the collections of animals and plants on a geographic basis, versus a species basis. Added later were smaller pavilions housing animals from the Americas and Australasia.



An important design element of the structures is the copper roofs featured on many of the pavilions. Copper, due to its superior performance
and lack of maintenance requirements is the perfect material for these soaring structures. Combined with its long service life, which can
extend hundreds of years, copper was the best roofing choice, especially considering how its great natural beauty plays off the zoo's
Rouge Valley setting.



As you can see from the accompanying images, the copper has progressed from its initial salmon-red colour through brown and black,
and is just blossoming now into its natural greenish-gray colour. The irregular shapes of the roofs themselves have slowed this process
down from what would normally be expected. However, in terms of performance, it is expected that the roofs will perform for many more decades.
