Design, Approvals & Compliance Hub
Designing and building in NSW involves far more than a council approval — and this hub is built to support every stage of that journey. Here you'll find free floor plan references, construction cost estimating tools, DA & CDC checklists, council DCP lodgement guides, and drawing package standards used on real projects across Sydney and regional NSW. We cover every approval pathway — exempt development, Complying Development Certificates issued by private certifiers, council Development Applications, Construction Certificates, Building Information Certificates, and Section 4.55 & 4.56 modifications — across all building classes under the National Construction Code, from granny flats and duplexes to commercial, industrial and mixed-use developments. New guides, tools and industry updates are added continuously as regulations, fees and planning policies evolve.
