FAQ: Duplex Builders Newcastle
How much does it cost to build a duplex in Newcastle?
The cost of building a duplex in Newcastle depends on several factors including site conditions, design, finishes, access, and service connections. We recommend speaking with our team to get an accurate estimate based on your block and development goals.
Is building a duplex a good investment in the Hunter Valley?
Yes — duplexes are a popular investment in the Hunter Valley due to rising rental demand, land value growth, and the ability to generate dual income. Many investors build and hold, while others sell one or both dwellings to release equity.
Do I need council approval for a duplex in Newcastle?
Yes. All duplex builds require development approval (DA) from Newcastle City Council or your relevant local authority. We can assist with builder estimates based on DA-approved plans.
Can you build on battle-axe or sloping lots?
Absolutely. We have extensive experience building on complex sites, including battle-axe lots, sloping blocks, and irregular land parcels. Our team will assess your site and recommend practical construction solutions.
How long does it take to build a duplex?
Construction time usually ranges from 6 to 9 months, depending on design complexity, weather, and approvals. We provide a clear timeline as part of our contract.
