Planning is under way to accommodate more than 740,000 people in Perth's north-west by 2050, more than doubling the current population.
Planning Minister John Day said Perth and Peel@3.5million had identified enough land for urban and employment to meet the expected demand for homes and jobs in the sub-region.
The draft framework covers land use in the cities of Wanneroo and Joondalup.
"While the current population of 322,000 people was distributed relatively evenly between Wanneroo and Joondalup, the rate of growth will be considerably stronger in Wanneroo due to the availability of urban zoned land and continued demand for coastal living," Mr Day said.
"Almost 50,000 of the required homes will be provided through greater infill development at activity centres such as Joondalup, transport corridors and station precincts, coupled with greater residential density and mixed-use development to revitalise existing suburbs. The emerging centres at Yanchep and Alkimos will provide significant numbers of homes.
"Urban expansion and investigation areas have been identified at East Wanneroo and South Pinjar and form a logical consolidation of the existing urban areas."
Almost twice the amount of employment-generating land required to meet projected demand has been identified in the sub-region with a substantial reserve in Nowergup, North and South Pinjar and Carabooda, as well as undeveloped land at the existing industrial centres of Neerabup and Wangara.
The Minister said boosting employment options across the sub-region would require strengthened access to existing and planned transport infrastructure in other sub-regions.
"The north-west's proximity to the north-east sub-region and the potential intermodal terminal at Bullsbrook could maximise this economic advantage," he said.
"An upgrade to existing roads will facilitate urban development within the Yanchep-Two Rocks and east Wanneroo areas. A potential future extension of the northern suburbs passenger railway from Butler to Yanchep will link activity centres and provide employment opportunities.
"In addition, a second rail option from Clarkson to the central business district is being investigated. These transport initiatives will contribute to reducing the reliance on roads."
