Dual Occupancy Specialists Turrella — Licensed Duplex Builder
NSW licensed duplex builder in Turrella 2205. Torrens or strata subdivision, Bayside Council planning expertise, full contract management for investor-grade builds.
Quick Answer
A duplex in Turrella 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.
Turrella Dual Occ. — Feasibility to Handover
A duplex in Turrella works on the larger blocks in a quiet rail-line pocket between Arncliffe and Bardwell Park. Lots run 400 to 650m2 against the 600m2 Bayside duplex minimum, so the larger ones clear it and the smaller fall short. On a $1.5M to $2.2M market with a station in the suburb, a Torrens-title duplex on a qualifying block is a sound play.
The ground is Wianamatta Shale with sandstone outcrops on the Wolli Creek valley fall, so footings and the slab are engineered to suit, and Wolli Creek riparian setbacks apply on the valley-side blocks. ANIP flight-path overlays add acoustic requirements, and the inter-war and post-war stock carries asbestos, stripped under licence.
What I would check first on your Turrella block: the area against 600m2, any Wolli Creek riparian setback, and the flight-path overlay.
We build these fixed-price, licence HBL 487805C. Send me the block and I will tell you what it carries.

Larger blocks against 600m2
Turrella lots run 400 to 650m2 against the 600m2 Bayside minimum, so the larger ones clear it.
A station in this quiet pocket gives a completed duplex steady demand at the $1.5M to $2.2M market.
Riparian setbacks and flight path
Wianamatta Shale with sandstone on the Wolli Creek valley fall means footings and slab engineered to suit.
Wolli Creek riparian setbacks and ANIP flight-path overlays are confirmed before design.

How It Works
From First Call to Final Key
A duplex is really a feasibility problem wearing a construction outfit. Before anything else, we verify your Turrella block against Bayside Council's LEP — lot size, frontage, FSR, landscape area. If it doesn't stack up, you find out in a week, not after 3 months of design.
⏱Design runs dual from day one. Two dwellings, one coherent streetscape, party-wall acoustics and fire rating built into the structure rather than bolted on. The plan accommodates R2 Low zoning without looking like two mismatched houses sharing a fence.
⏱Approval and construction get sequenced together. Slab pours are choreographed so the trades show up once, frame up both sides, and keep rolling. Two separate meters, two separate services, but one crew, one programme.
⏱Handover is dual. Both dwellings walked at the same time, both OCs in the same issue, both titles subdivided before settlement. You leave the final inspection with the option to live in one and rent the other, or to sell both.
⏱Quality Promise
Turrella dual occupancy construction: feasibility assessment first, then fixed-price build to dual handover. No surprises.
