Duplex Clovelly — Feasibility, Design, Approval & Build
End-to-end duplex delivery in Clovelly 2031: yield analysis, design for R2 Low zoning, Randwick City Council approvals, subdivision coordination, construction, separate services and handover.
Quick Answer
A duplex in Clovelly costs $750,000–$1,500,000+ for dual occupancy construction. Attached duplex from $750K, detached from $1M. Buildana manages feasibility, Randwick City Council approvals, construction and subdivision under one fixed-price contract.
Clovelly Dual Occ. — Feasibility to Handover
A duplex in Clovelly is uncommon, because the lots are tight, heritage covers most streets, and Randwick controls attached dwellings by frontage and area rather than a simple lot minimum. This small beachside village between Coogee and Bronte runs Federation cottages and inter-war heritage on 250 to 600m2 blocks, and on a typical lot the honest answer is a single designed home or a restoration. Heritage Conservation Areas cover most older streets, so dual-occupancy is constrained or precluded on contributory lots.
The ground is sandstone-dominant with substantial fall to Clovelly Bay, so coastal salt-grade specs are standard and rock is priced honestly, and a duplex on a tight heritage-adjacent block is rarely feasible. I would rather give you the honest read than push the wrong scope. Where the existing home carries fibro a licensed asbestos strip-out comes first.
What I would check first on your Clovelly block: the heritage status, the frontage and area against Randwick's attached-dwelling controls, and the sandstone fall. That decides the direction.
We build these fixed-price, licence HBL 487805C. Send me the address and I will tell you honestly what the block suits.

Tight lots, heritage streets
This beachside village runs Federation and inter-war stock on 250 to 600m2 blocks, with Conservation Areas over most older streets.
Randwick controls attached dwellings by frontage and area, and on a contributory lot dual-occupancy is constrained or precluded.
Coastal fall and salt
The ground is sandstone-dominant with substantial fall to Clovelly Bay, so coastal salt-grade specs are standard and rock is priced honestly.
A duplex on a tight heritage-adjacent block is rarely feasible, with older fibro stripped under licence first.

How It Works
From First Call to Final Key
Quick desktop check first — lot size, zoning, frontage — then full site visit if it stacks. Drainage path, neighbour overlooking, slope, services, easements. 600m² minimum is just the entry ticket; the real feasibility is whether two compliant dwellings actually fit and sell.
⏱Our architect designs both dwellings to maximise your Clovelly block's yield — floor plans, elevations, 3D renders, and landscape concept. We optimise for rental return and sale value under Randwick City Council's DCP.
⏱Most Clovelly duplexes go DA route through Randwick City Council — CDC pathways for dual occupancy are restrictive on most R2 blocks. We pre-meet with council planners on borderline sites to confirm support before lodgement, which avoids a 3-month round trip on RFIs.
⏱Both dwellings built simultaneously — engineered slabs (Class M soil), frame, lock-up, fit-out. Milestone updates from your project manager.
⏱Final inspections, dual OCs issued, subdivision registered with LRS. Each dwelling gets its own title, services, and 6-year structural warranty. Ready to rent, sell, or occupy.
⏱Quality Promise
We build duplexes in Clovelly end-to-end — feasibility, design, DA/CDC, dual-slab construction, subdivision. One contract.
