A duplex in Ramsgate costs $750,000–$1,500,000+ for dual occupancy construction. Attached duplex from $750K, detached from $1M. Buildana manages feasibility, Bayside Council approvals, construction and subdivision under one fixed-price contract.
Ramsgate Duplex Construction
A duplex in Ramsgate works on the larger blocks in the inland part of the village. Lots run 450 to 700m2 against the 600m2 Bayside duplex minimum, so the larger ones clear it and the smaller fall short. On a $1.7M to $2.5M market with R3 along Rocky Point Road, a Torrens-title duplex on a qualifying block is a sound play in a family-oriented established suburb.
The ground is a Botany Sands and Wianamatta Shale interface, so footings and the slab are engineered to suit the site, and the ANIP flight-path overlays add acoustic requirements worth confirming. The inter-war and post-war stock carries asbestos on the older homes, stripped under licence.
What I would check first on your Ramsgate block: the area against 600m2, the flight-path overlay, and the frontage for two dwellings.
We build these fixed-price, licence HBL 487805C. Send me the block and I will tell you what it carries.
Buildana manages the full duplex development process in Ramsgate — 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.

Inland blocks against 600m2
Ramsgate lots run 450 to 700m2 against the 600m2 Bayside minimum, so the larger ones clear it.
R3 along Rocky Point Road adds a medium-density option worth checking on the right block.
Sand-shale ground and flight path
The Botany Sands and Wianamatta Shale interface means footings and slab engineered to suit the site.
ANIP flight-path overlays add acoustic requirements, and older stock is stripped of asbestos under licence.

How It Works
From First Call to Final Key
Feasibility covers the planning side and the financial side. Yes-or-no on whether the block supports dual occupancy under Bayside Council controls, plus indicative end values, build cost, and likely yield.
⏱Dual occupancy floor plans designed for your Ramsgate block — attached or detached configuration, vehicle access, private open space, and full Bayside Council compliance..
⏱Full approval management: Statement of Environmental Effects, plans, reports, and all supporting documentation lodged with Bayside Council or private certifier. We handle RFIs and conditions.
⏱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.
⏱Both dwellings handed over with individual Occupation Certificates. Subdivision lodged for separate titles.
⏱Quality Promise
Our Ramsgate duplex projects run from feasibility to subdivision under one builder. Fixed price, dual handover, full compliance.
