A duplex in Narellan is a feasible dual-occupancy on the lots that clear the Camden 450m2 minimum, with R3 adding options. This main retail and commercial centre of the LGA runs 1980s to 2000s residential streets around the Narellan Town Centre, and the R2 and R3 zoning supports a range of residential development, so a Torrens-title duplex on a qualifying lot is a sound play. Some estate lots are compact, so the area is the first check.
The western edge carries Class H reactive clay pockets, so footings are engineered off geotech and the slab detailed for the movement on both dwellings where the clay is reactive. On a qualifying block a side-by-side works cleanly, and where a lot carries R3 a medium-density option is worth checking. Where the existing home carries fibro a licensed asbestos strip-out comes first.
What I would check first on your Narellan block: whether it clears the 450m2 minimum, the Class H clay on the western edge, and any R3 potential. 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.
