If you are looking at where people are building new homes in Perth, the answer is closely tied to where new land is being unlocked. Right now, much of that activity is concentrated in Perth’s northern and southern growth corridors, along with some emerging north-east and south-east areas. These locations continue to attract buyers because they offer newer estates, land supply, and the opportunity to build rather than compete for older housing.
Why these corridors matter
Perth’s growth corridors are where land, infrastructure, and future community planning are coming together. In 2024, the WA Government announced a major metro land supply boost through Karnup and Eglinton, expected to deliver more than 6,300 new residential lots. More recently, the state has continued to support land release and housing infrastructure through DevelopmentWA activity and budget commitments tied to key growth areas.
The northern corridor
Perth’s northern corridor remains one of the strongest areas for new home building. Places like Yanchep, Alkimos, and Eglinton continue to stand out because they combine new land supply with major transport, town-centre, and community planning.
A good example is the new Peet community in Yanchep, being delivered in partnership with DevelopmentWA. Construction began in 2026, with the project expected to deliver around 700 homes and a primary school, close to Yanchep Train Station and the future Yanchep City Centre.
Alkimos is another major part of that story. DevelopmentWA’s Alkimos Foreshore project and the broader Alkimos Central planning activity continue to reinforce the northern corridor as one of Perth’s most active areas for future residential growth.
The southern corridor
The southern corridor is also a major drawcard for people building new homes, especially where larger greenfield communities are still being planned.
Karnup is one of the clearest examples. The WA Government announced in late 2025 that around 4,000 residential lots would be created there.
This area is not just another estate release. It is tied into broader planning and transport thinking, including the Karnup Station precinct and the City of Rockingham’s wider district structure planning.
Other areas where people are building
While the northern and southern corridors dominate the bigger land-release story, they are not the only places attracting people who want to build.
In the north-east, Bullsbrook is becoming increasingly relevant. Mirvac’s Darling Bullsbrook has started construction and is expected to deliver approximately 1,200 homes.
In the south-east, Hilbert continues to attract people wanting to build new homes in a newer suburban setting rather than buy established stock.
Why people are choosing these areas
The reason people are building in these parts of Perth is not just affordability. It is also about access to newer estates, more flexible lot choices, and the chance to design a home around a new block rather than adapt to an older property.
That said, the trade-off is that some of these areas are still growing into their full level of amenity. Schools, retail, transport convenience, and local services may be still be developing.
Conclusion
Perth’s northern and southern growth corridors are where a large part of the city’s new land supply is being unlocked. Areas like Yanchep, Alkimos, Eglinton, Karnup, Bullsbrook, and Hilbert continue to stand out because they offer land, growth potential, and the chance to build in newer communities rather than buy established homes in tighter markets.
