The Hidden Duplex Costs That Can Destroy Your Profit if You Miss Them Early

Many people decide to build a duplex for one clear reason: profit. On paper, the numbers can look strong. Two dwellings. Two income streams. A clear path to growth. But that profit can disappear very quickly when key costs are overlooked at the start.

What most people do not realise upfront is that duplex projects often involve expenses beyond design and construction. State government levies. Council contribution fees. Infrastructure and service charges. These costs are rarely included in early estimates, yet they directly impact your return.

This is where many duplex projects quietly go wrong. The design looks right. The build cost feels reasonable. But once approvals progress and additional charges surface, the numbers no longer stack. What looked profitable early on starts eroding fast.

The problem is not the duplex. It is the lack of early feasibility. Without identifying every cost before committing, decisions are made with incomplete information, and that can be expensive.

At Neogen Homes, duplex feasibility comes before commitment. We identify approval-related costs, infrastructure requirements, and contribution fees early so you understand the real financial picture from the beginning.

If you are considering a duplex and want clarity before you move forward, the right information makes all the difference.
