You’d like to build and unsure where to start the process. Especially what to allow for in terms of cost and time.
We recommend using this calculator to start. Ask your builder what their approximate cost to builder per square metre or where they sit on the scale from project/kit home builder to architectural high end finish. https://www.aaarchitect.com.au/home-building-costing-calculator.html
We also have a budget spreadsheet that can help prompt you with all of other items eg. geotech, surveyor’s fees, soil sediment, fencing, driveway, services, furniture and so forth
