A duplex can unlock significantly more from a single block, but only if the design, approvals and build are handled properly. DVELOP builds duplexes with a developer’s eye on cost, finish and resale.
Recent DVELOP duplexes include two projects on Crossland Street, Merrylands.
Is your block suitable for a duplex?
Whether a duplex is allowed depends on the zoning, lot size, frontage and council controls — and whether it can go through the faster complying development pathway or needs a DA. We check the planning controls on the NSW Planning Portal before you commit to design.

Questions
Duplex Builders FAQs
Do I need home building compensation insurance?
In NSW, residential building work over $20,000 requires home building compensation (HBC) cover to be in place before work starts or a deposit is taken. It protects the owner if the builder can’t complete or fix defects due to insolvency, death or disappearance.
Will I get a written contract?
Yes. Every DVELOP project is documented with a written contract setting out scope, price, inclusions and program. In NSW, residential building work over $5,000 requires a full written contract, and smaller jobs over $1,000 still need a written small-jobs contract.
Can I subdivide the duplex afterwards?
Often yes, by strata or Torrens title depending on the approval and council controls. We plan subdivision into the project from the start.
