Cost depends on block size, council overlays, party wall engineering and your choice of finishes, so there’s no single figure that applies across Melbourne. Get a fixed-price tender for your specific block rather than relying on a generic per-square-metre estimate.

Timeframes depend on council approval speed, design complexity and site conditions, so this varies project to project. Ardmillian provides a clear timeline as part of your fixed-price tender once your design and permits are confirmed.
