"One of the key elements was looking hard at the buildings we did have and thinking about what our needs might be in 10 or 20 years," Mr Simmonds said.
"The key point is having the flexibility to develop. You can put in all the energy-saving light bulbs in the world, but if you then have to re-purpose the building at great expense because it wasn't thought about for the long term, then that negates all of that."
Sustainability began at the most fundamental level, with builders expected to recycle a minimum of 75 per cent of the waste materials, and some of the old cladding timber reused in three different places in the new build.
A number of environmental consultants have worked on the project. A key role on redesigning buildings was taken by architectural design firm Jasmax, which has a strong reputation in the environmental area, and designed Sharp Tudhope's award-winning new headquarters. Environmental engineering design consultants Boffa Miskell advised on the landscape features, which have been a major feature of Comvita's environmental commitment and include the installation of a natural waste water treatment system for the site.
"We can't have all the sustainability we'd like at once, but we've created a path towards it," said Mr Simmonds. "Good design is sustainable because it makes sure that everything is right for the long term."
