Block sizes have shrunk and risen in price much more substantially than the cost to of building.
This is nothing new HJ.
Go for a drive around the Melb CBD fringe, and see what sort of houses were built back when the end of civilsation was that fringe, or indeed the "outer suburbs".
Places like Collingwood, Richmond, Northcote and so on - thousands of dog-box terrace houses on tiny little handkerchiefs of land - the edge of the suburban sprawl, but lots of demand and not a lot of available land at the time.
This is still happening in all the areas where there is a lot of demand from people who want to live closer in the the popular areas, some 150 or more years later..
Amazingly, it is often the view of the younger folk - on SS and in the wider community - they bleat about how hard it all is like it just happened last year when
they decided to start looking for a place of their own;
"blocks are shrinking! costs are soaring!" and so forth.
Why do you think suburbs like Burwood - which was the end of civilisation when I was a kid - popped up all over the Country?
I remember as a 4 or 5 year old, getting off the tram at the end of the line on what is now the Burwood highway, and walking down a dirt road with my mother to visit my Auntie in their newly built home....
It was because it was cheaper to buy, cheaper to build, land was cheaper per square foot than in Preston etc, so folk started moving out there.
Nothing's really changed; just the next generation of players, and the edge of civilisation where houses were affordable has moved further out.
Has the cost of building really increased more as a % of income for the average wage earner in the last 100 years or so? I reckon it probably has a bit actually, despite what I just said.
But housing is still affordable - it depends where you are looking and the style of dwelling.
But look at why the cost of building has gone up; Workcare premiums, superannuation guarantees, penalty rates over 37.5 hour weeks, redundancy pay-outs, unfair dismissal payouts and costs, safety regulations and compliance costs, increased govt charges and fees at every stage of a house design and construction - planning and permit fees, bushfire overlay plans and fees, GST....the list goes on.
Half of these things weren't around 100 years ago. You went to work, did your job or you got sacked.
People got injured, sure; and now we have a much safer building industry, but now it costs probably the same as one employee to ensure that 5 others aren't injured - every year, and it's never going away..
