Letting developers ditch car bays for new apartment buildings is one radical measure Perth’s peak property industry body is proposing to triple the city's residential population.

On Friday, the Property Council WA will launch its Project 90K report at an event at which City of Perth, state and federal government representatives will discuss the Perth City Deal.

Perth is one of the last cities to secure and announce how it will use the federal funding jackpot termed a “city deal”.

The deal and the Project 90K report will focus on a goal to triple Perth city’s population to 90,000 by 2050, from a base of 30,000.
