Create a nfp or gov owned company, to facilitate young people becoming the property developers themselves where multiple 1st home buyers can buy land and build together on one block far cheaper than buying from for profit developers.

This company would oversee and manage the whole process of the building of the development, but the buyers, first home buyers, would have much more say in how their part would be built and would buy in from the beginning. There are many big blocks where one house is knocked down and turned into multiple apartments or townhouses but are then sold at high prices and the developers make a good profit. Why not support first home buyers to be the developers and have a government owned company that facilitates this to ensure a more affordable price for the first home buyers.
