Housing shortfall, costs and affordability

[plam]

What are one or two things you think the construction industry could do to become less wasteful and more efficient

I’m not an expert, I just know that process engineers in manufacturing have been driving remarkable efficiency gains for 70 years now - keeping prices low.

None of that professional introspection and investment applies in home building. Why do we still do it the same way for decades? An auto worker from the 70s wouldn’t recognize an auto plant today.

There are houses that are prefab, which probably helps. But probably it's because there's no real incentive to build houses cheaper when the house prices keep going up. (NZ complains about this problem but also the problem that house quality kind of sucks; I'd never heard people talking about warm and dry houses because that just goes without saying in most Canadian houses.)
