NSW's low- and mid-rise housing reforms are progressively lifting what's permissible near centres and transport across the state, so a Seven Hills site's potential today can differ from its history. Exact controls — zone, height, floor-space ratio, minimum lot size, heritage and any coastal or environmental overlays — vary by address, planning instrument, site and proposal. Confirm them for a specific site.
