Duplex builder in Rydalmere

Rydalmere is our home suburb. AGA Building is a family-run, licensed builder based here, and we’ve designed and built two duplexes in Rydalmere, completed in 2021 and 2023. Andrew supervises every job on site, and in Rydalmere that site is just around the corner.

Can you build a duplex in Rydalmere?

Rydalmere is in the City of Parramatta. It has industrial land and the Western Sydney University campus, but its house streets are mostly zoned R2 Low Density Residential, where duplexes are allowed. Rydalmere isn’t one of the station or town centre areas in the NSW Low and Mid-Rise Housing Policy, so the City of Parramatta’s own minimums apply:

Control	Rydalmere (Parramatta LEP 2023)
Minimum lot size for a duplex	600 m²
Minimum lot width	15 m

What we check on Rydalmere blocks

• Flooding. Rydalmere runs down to the Parramatta River, and blocks near the river or low-lying creek lines can be flood-affected, which changes floor levels and design.
• Slope and drainage. Streets falling toward the river often need careful stormwater design, and sometimes an easement.
• Neighbouring land. Blocks near industrial or university land can have extra noise or traffic considerations.
• Lot width. Many older blocks are close to 15 m wide, so an accurate survey matters.

CDC or DA in Rydalmere?

A regular block that meets every standard and isn’t flood-affected may suit a complying development certificate (CDC), which is usually faster. Flood-affected or undersized blocks normally go through a development application (DA) to the City of Parramatta. We work this out at the start and manage the approval for you.

Our Rydalmere duplexes

We designed and built both of our Rydalmere duplexes from start to finish: the 2021 duplex and the 2023 duplex. We’ve also built in neighbouring Ermington and nearby West Ryde, and we build in Dundas, Telopea and Carlingford.

Rydalmere duplex questions

How do I know if my block is flood-affected?

A Section 10.7 planning certificate from the City of Parramatta shows whether flood controls apply. We check flood information as part of our free block check.

Can I see one of your Rydalmere duplexes?

Our project pages show photos of both. Give us a call and we can talk you through how they were designed and built.

What will a Rydalmere duplex cost?

It depends on the size, finishes and any flood or drainage requirements. Our duplex cost guide covers the main costs, and we’ll give you a realistic budget once we’ve seen the block.
