Duplex Builder in Miller
A duplex in Miller is an affordable dual-occupancy on the lots that clear the Liverpool 600m2 minimum. This established residential suburb runs 1960s to 1980s housing stock on standard blocks with renewal opportunity, and at a $700K to $900K median a Torrens-title duplex on a qualifying lot is one of the more affordable ways into dual-occupancy yield in Liverpool LGA. Some standard lots fall short, so the area is the first check.
This is Liverpool LGA on reactive clay, so footings are engineered off geotech and the slab is detailed for the movement on both dwellings. On a qualifying block a side-by-side duplex works cleanly, and there are no broad heritage overlays. Where the existing home carries fibro a licensed asbestos strip-out comes first.
What I would check first on your Miller block: whether it clears the 600m2 minimum, the reactive-clay footing design, and the frontage. Those set the dual-occ.
We build these fixed-price, licence HBL 487805C. Send me the block and I will tell you what dual-occupancy it carries.
