A duplex in Dulwich Hill is uncommon on the standard blocks, because the lots are tight and heritage is extensive, though R4 near the station opens density. This rail-line suburb between Marrickville and Lewisham runs Federation cottages, inter-war heritage, terraces and apartments on 200 to 450m2 blocks, and on a typical lot the honest answer is a single designed home or a Federation restoration. Heritage Conservation Areas are extensive, so dual-occupancy is constrained or precluded on contributory lots, while R4 around the station and light rail opens medium or high density.
The ground is Wianamatta Shale, engineered off geotech, and the strong Federation restoration market means many lots are best kept and restored. A duplex on a tight heritage-adjacent block is rarely feasible, so I would rather point you to the R4 option or a restoration than push the wrong scope. Where older homes carry fibro a licensed asbestos strip-out comes first.
What I would check first on your Dulwich Hill block: the heritage status, the tight-lot area, and any R4 near the station. 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.

How It Works
From First Call to Final Key
Site visit, title search, and planning assessment for your Dulwich Hill block. We check lot dimensions against Inner West Council's minimum (Varies by precinct (terraces dominant — duplex feasibility limited)), review overlays, drainage, access, and services.
⏱Design has to satisfy four audiences at once: Inner West 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.
⏱We lodge and chase your approval — DA through Inner West Council for most duplexes, or CDC where eligible. R1/R2 General/Low zoning in Dulwich Hill.
⏱Building both sides in parallel halves the loan interest holding cost vs sequential builds. Bulk material orders for cabinetry, tiles, fixtures cut unit cost.
⏱Strata or Torrens title subdivision completed. Separate OCs, individual metering, 6-year structural warranty per dwelling.
