Maximise the yield on your block with a duplex designed by architects who know what your council will and will not approve. One team handles design, engineering, certification and council liaison.
Free feasibility check. No obligation. We will tell you straight if your block does not stack up.
DA-approved duplexes that maximise your block's yield.
You bought (or are buying) the block specifically to develop a duplex for yield or resale. You want feasibility numbers before any design work, fast turnaround to CC, and Torrens or strata subdivision drawings included in scope.
"I'd been burned by a previous architect on a duplex DA that got knocked back twice. Nemco redrew it, talked us through what council actually wanted, and got it through first try. Fixed fee, no surprises."
Not every block can take a duplex. Council rules on minimum lot size, frontage, FSR (Floor Space Ratio) and setbacks vary suburb by suburb across Sydney. Get this wrong and you'll spend $20k on plans for a project that never gets approved.
We do a feasibility check before any design work — for free. You'll know within a week whether your block stacks up.
Every specialist your duplex needs in one office, on one fee, with one number to call when you want to know where the project is at.
A spread of recent duplex approvals across Sydney — Northmead, Willoughby, Sylvania Waters and beyond. Different councils, different block sizes, same fixed-fee process.
