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.

Buildana manages the full duplex development process in Clovelly — 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.

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.
