Project Toorak Garden exemplifies the principles of sustainable design through its thoughtful approach to extending a 19th-century brick building. By reconfiguring internal walls and introducing a new kitchen, living, and dining area, the project honors the integrity of the original structure while embracing modern functionality. This method not only preserves the building's history but also minimizes waste, aligning seamlessly with the ethos of sustainability. The result is a harmonious blend of old and new, showcasing how considerate design can create timeless, sustainable spaces that respect both heritage and the environment.
