Quality and consistency through collaboration

Sydney Environment & Planning

Environmental planning is the process of guiding decisions related to land development while taking into account the natural environment, as well as political, social, economic, and governance factors. This process provides a comprehensive framework aimed at ensuring sustainable long-term outcomes, with applicable legislation informing various aspects such as planning administration, planning instruments, the assessment of development applications, building certifications, appeals, and enforcement.

Through a series of environment and planning case studies, particularly focusing on examples from the Sydney Metropolitan area, we break down the complex laws and policies associated with the environment and planning regime in New South Wales.
