DUPLEX

A duplex is essentially two builds happening at once, and the projects that run smoothly are the ones where that's treated as an advantage rather than double the complexity. Mirrored unit design lets us run trades across both dwellings in parallel rather than sequentially, which compresses the program and reduces cost compared to treating each side as a separate build. We build subdivision potential into the DA strategy from the outset where that's the client's intent, because retrofitting a subdivision plan after construction is finished is far more difficult and expensive than planning for it up front. The same accountable team carries the project through design, council approval, construction and both individual handovers, which matters for owner-builders and investors who are usually trying to maximise yield and resale value without the process turning into two separate headaches instead of one coordinated project. We also manage the practical friction points specific to dual occupancy — shared driveways, separate service connections, two sets of certification and, often, two different buyers or tenants with different expectations of finish and handover date. Getting the sequencing right early means neither dwelling waits unnecessarily on the other.
What we do differently
Mirrored-unit design lets us run trades across both dwellings in parallel, compressing program and cost compared to treating each side separately. We build subdivision strategy into the DA from the outset where that's the goal, and one accountable team carries the project through both individual handovers.
Why trust AFA
In-house architectural and construction leadership under one roof means duplex projects aren't split across firms that don't talk to each other. ISO 9001 certified processes, family-run accountability since 1994, and a track record focused on maximising yield and resale value for duplex owners across NSW.
