A duplex in South Maroota is a different conversation entirely, because this is acreage, not suburban land. Holdings run 2 to 10 hectares and more on RU2 Rural Landscape zoning, so the standard R2 dual-occupancy rules do not apply the way they do in the suburbs. What works here is usually a primary dwelling plus a secondary dwelling or rural dual occupancy under the Hills DCP, assessed against the rural controls.
The ground is Hawkesbury Sandstone, so footings are engineered off geotech, and the suburb is significantly bushfire-prone, so any dwelling meets its BAL construction standard. Hawkesbury River foreshore proximity and Cattai Creek riparian setbacks shape where you can build.
What I would check first on your South Maroota holding: the RU2 controls, the bushfire rating, and the riparian setbacks, because those govern any second dwelling far more than a suburban duplex minimum.
We build these fixed-price, licence HBL 487805C. Send me the holding and I will tell you honestly what a second dwelling here can look like.
Buildana manages the full duplex development process in South Maroota — from feasibility assessment and architectural design through to DA or CDC approval, and fixed-price construction to dual handover. One builder, one contract, two homes.

Acreage, not suburban duplex land

What works is usually a primary plus secondary dwelling or rural dual occupancy under the Hills DCP.
Bushfire, rock and riparian
Hawkesbury Sandstone means footings engineered off geotech, and the suburb is significantly bushfire-prone.
Any dwelling meets its BAL standard, and Cattai Creek and river-foreshore setbacks shape where you can build.

How It Works
From First Call to Final Key
Everything that has to be right before we touch the ground. Feasibility covers the planning side and the financial side. Yes-or-no on whether the block supports dual occupancy under The Hills Shire Council controls, plus indicative end values, build cost, and likely yield. The point is to kill bad sites before you spend on design — not after. Dual occupancy floor plans designed for your South Maroota block — attached or detached configuration, vehicle access, private open space, and full The Hills Shire Council compliance.
⏱The South Maroota construction phase. Fixed price, programmed, supervised. Full approval management: Statement of Environmental Effects, plans, reports, and all supporting documentation lodged with The Hills Shire Council or private certifier. We handle RFIs and conditions. CC follows. Construction follows a tight programme: dual slabs in one mobilisation, paired frame stand, simultaneous lock-up, then trades rotate between sides for fit-out so no day is lost waiting on availability. The schedule is engineered, not optimistic.
⏱The job isn't done when the site's clean; it's done when you have keys, certificates and warranties. Both dwellings handed over with individual Occupation Certificates. Subdivision lodged for separate titles. Separate metering installed. 6-year structural warranty per dwelling.
