Leaders in Environmentally Sustainable Design

Ark Resources has been at the forefront of environmentally sustainable design since being established in 1999. We have extensive experience in all building types and have provided advice for buildings and developments of every scale, ranging from individual houses to several of Melbourne’s most significant residential and commercial projects.

We provide sustainability input at all stages of the property development cycle from concept design, through planning application, design development, construction, commissioning and post-occupancy.

We have expertise in the development of ESD frameworks and policies and have developed several highly regarded sustainability rating tools for all levels of Government.
