A duplex in Wheeler Heights costs $750,000–$1,500,000+ for dual occupancy construction. Attached duplex from $750K, detached from $1M. Buildana manages feasibility, Northern Beaches Council approvals, construction and subdivision under one fixed-price contract.
Building Duplexes in Wheeler Heights
A duplex in Wheeler Heights works on the larger blocks, but the ocean-view fall and the rock shape the call. This elevated post-war Northern Beaches suburb runs 500 to 800m2 R2 blocks, so the larger ones clear the 600m2 minimum. On a $2.4M to $3.6M market, an inland block suits a duplex while a block on the eastern fall with Long Reef and ocean views often makes more as a single home.
The ground is Hawkesbury Sandstone, so deep rock excavation at $40K to $100K is typical, and a duplex spreads that across two footprints. The 1950s to 1970s stock carries asbestos, stripped under licence, and footings are engineered off geotech to suit the sandstone.
What I would check first on your Wheeler Heights block: the area against 600m2, the rock, and whether the outlook favours a single home over a duplex.
We build these fixed-price, licence HBL 487805C. Send me the block and I will tell you honestly what makes the most of it.

Sandstone and deep rock

How It Works
From First Call to Final Key
Everything that has to be right before we touch the ground. Site visit, title search, and planning assessment for your Wheeler Heights block. We check lot dimensions against Northern Beaches Council's minimum (600m² (Manly/Pittwater legacy R2) / 700m² (Warringah legacy R2) / varies by precinct under Northern Beaches LEP), review overlays, drainage, access, and services. You get a clear yes/no on duplex feasibility plus estimated yield. Design has to satisfy four audiences at once: Northern Beaches Council, the future buyer or tenant, the certifier, and you. Each pull in a different direction — our job is to land plans that work for all four. Solar access, privacy, parking, POS, FSR, all balanced.
⏱The Wheeler Heights construction phase. Fixed price, programmed, supervised. We lodge and chase your approval — DA through Northern Beaches Council for most duplexes, or CDC where eligible. R2 Low zoning in Wheeler Heights. CC issued, conditions cleared, ready to build. Building both sides in parallel halves the loan interest holding cost vs sequential builds. Bulk material orders for cabinetry, tiles, fixtures cut unit cost. Single site setup, single supervisor, single insurance period — efficiency compounds across the whole programme.
⏱The job isn't done when the site's clean; it's done when you have keys, certificates and warranties. Strata or Torrens title subdivision completed. Separate OCs, individual metering, 6-year structural warranty per dwelling. Strong rental demand near B-Line bus to CBD (Collaroy interchange) station.
⏱Quality Promise
We build duplexes in Wheeler Heights end-to-end — feasibility, design, DA/CDC, dual-slab construction, subdivision. One contract.
