A duplex is a single building containing two separate dwellings, typically side-by-side or one above the other, each with its own entrance and facilities. While not as common as detached houses, duplexes do exist within the Melbourne property market.
Currently in Melbourne, duplexes are more frequently found in established inner and middle-ring suburbs, and occasionally in areas like the eastern suburbs Fletchers services – including Box Hill, Doncaster, and Ringwood. As of December 2025, zoning regulations significantly influence their availability. Many Melbourne councils have restrictions on creating new duplexes, favouring single-dwelling zoning, although there’s increasing discussion around medium-density housing options in 2026. When selling a property with duplex potential, it’s important to understand the local council’s planning scheme. Buyers interested in duplexes often consider the potential for rental income from one dwelling while occupying the other, or the possibility of subdivision (subject to council approval). In 2026, buyers are increasingly factoring in long-term investment potential and the ability to add value through renovation or development. Property appraisals from experienced agents, like those at Fletchers, will consider these factors. Typical marketing campaigns for properties with duplex potential emphasise the land size and zoning possibilities.
Duplexes represent a unique property type in Melbourne, offering potential for both owner-occupation and investment, but their availability is governed by local planning regulations.
