A duplex in Tamarama costs $750,000–$1,500,000+ for dual occupancy construction. Attached duplex from $750K, detached from $1M. Buildana manages feasibility, Waverley Council approvals, construction and subdivision under one fixed-price contract.
Tamarama Dual Occ. — Feasibility to Handover
I will be straight with you: Tamarama is not a duplex suburb. Sydney's smallest beachside enclave sits on tight 200 to 600m² blocks with Heritage Conservation Areas over most streets and substantial cliff-top fall to the beach. Between the block sizes, the heritage and the topography, a Torrens-title dual occupancy is effectively precluded here, and I would rather say so than take your feasibility fee.
What Tamarama actually rewards is a superb single home that works the ocean view and the fall, or a heritage-sensitive rebuild that respects the streetscape. In a $4M-plus enclave, that is where the value sits, not in forcing two dwellings onto a heritage cliff-top block that cannot carry them.
What I would check on your Tamarama block: the heritage listing, the fall and the sandstone, all pointing toward the best single-home outcome rather than a duplex with almost no path.
We build fixed-price, licence HBL 487805C. If you were set on a duplex, let me show you why a custom home is the smarter Tamarama play.
Buildana manages the full duplex development process in Tamarama — 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.

Why a duplex does not work in Tamarama
Three things stack against a duplex here. The blocks run 200 to 600m² and mostly fall short of any dual-occupancy minimum. Heritage Conservation Areas cover most streets, so demolishing a contributing cottage is restricted. And the cliff-top fall to Tamarama Beach makes fitting and separating two dwellings genuinely difficult. Add them together and a compliant duplex is off the table on almost any Tamarama parcel.
I would rather tell you that up front than draw plans that get refused. Tamarama is the smallest beachside suburb in Sydney for a reason, and the blocks and controls reflect it.
What actually adds value here
In an enclave with an ocean outlook and the Sculpture by the Sea coastline on the doorstep, the value is in one beautifully executed home that works the view and the fall, or a heritage-sensitive rebuild that keeps the streetscape. Building with the sandstone and the topography rather than against them is what holds and grows value here. I would rather build you one exceptional home than a compromised duplex.

How It Works
From First Call to Final Key
Free feasibility check on your Tamarama block. We measure frontage width, confirm zoning (R2 Low), check minimum lot size against 600m² requirement, and review Waverley Council's DCP controls.
⏱Two dwellings, one site — design is mostly about geometry. Frontage split, party wall position, garage stacking, private courtyard size, and the streetscape elevation a certifier will actually approve.
⏱DA through Waverley Council (40–90 days) or CDC (10–15 business days). Tamarama is zoned R2 Low.
⏱Dual construction runs 9–14 months. Engineered slabs sized for Class M soil, simultaneous frame-up, staggered fit-out for efficiency.
⏱Two homes, two titles, two OCs, two warranty packs. We hand over a clean documentation set per dwelling: certifier reports, BASIX certs, structural sign-offs, appliance warranties, maintenance schedules.
