This post tracks the growth in size of homes in the USA over the last forty years, identifying that homes are now 56% larger than those of four decades ago. It uses a cute video to do so.
It’s probably the same here in Australia, or even more so.
All new homes here seem to have ensuite master bedrooms and most would have either a fourth bedroom or another living space. The forty-year mark was about when open plan design came to popularity as well, making for larger open spaces.
Of contrasting interest would be a study of how much time people spend in these larger homes.
My guess is probably less.
Go here and check it out.
This copy of the video may not last long, but if it does you can watch it here.
