FAQ
Do I need council approval to build a duplex?
Yes, building a duplex requires council approval, as local zoning and planning laws dictate what can be constructed on a block. Factors like land size, frontage and infrastructure are assessed before approval is granted. Working with an experienced builder can help streamline this process and ensure compliance.
Can a duplex be customised to suit different needs?
Absolutely. Duplex homes can be customised in layout, finishes and design to suit your preferences or investment goals. You might choose identical dwellings for simplicity or vary floor plans to appeal to different buyers or tenants. Flexibility is a key advantage of duplex construction.
What should I consider before starting a duplex project?
Before starting, assess your block’s size, slope and orientation to ensure it can support dual dwellings. Also consider your long-term goals, whether that’s living in one home, selling both or renting one for income. Clear planning and design alignment are essential to achieving the best outcome.
