A duplex in Ingleside is not the right product, because this is a rural-residential acreage suburb zoned RU2, not a dual-occupancy market. The holdings run 1 to 5-plus hectares with bushland and horticultural character, and under RU2 Rural Landscape the honest option is a single dwelling plus a permissible secondary dwelling, not a Torrens-title duplex. The long-term Ingleside Precinct rezoning is paused and under review, so it does not change the current position.
On an acreage the build is a whole-of-site exercise: siting, a mandatory RFS Bushfire Protection Assessment with BAL-29 to Flame Zone universal, an AWTS on-site sewer, and deep rock at $80K to $200K-plus. Parts of the western edge sit under the Sydney Drinking Water Catchment overlay. For dual-occupancy yield, neighbouring residential suburbs make far more sense, and I will point you to them.
What I would check first in Ingleside: the RU2 zoning and what it permits, the bushfire, wastewater and catchment constraints, and the better dual-occ options nearby. That is the honest starting point.
We build these fixed-price, licence HBL 487805C. Tell me what you are after and I will point you to where a duplex actually works.

RU2 acreage, not a duplex market
This rural-residential suburb runs 1 to 5-plus hectare holdings zoned RU2 with bushland and horticultural character.
The honest option is a single dwelling plus a permissible secondary dwelling, and the paused Ingleside rezoning does not change that today.
Whole-of-site build
The build is siting, mandatory BAL-29 to Flame Zone bushfire assessment, an AWTS on-site sewer and deep rock at $80K to $200K-plus.
Parts of the western edge sit under the Drinking Water Catchment overlay, and for yield I will point you to residential suburbs.
