Lived here since the seventies and never been too cold or too hot, we have always had climate control in our homes and a lot of Aussies do likewise. Unfortunately landlords do not really casre whether their tenants are hot and cold so unless you pay a premium unlikely to get a climate controlled house.
We have central heating and a wood stove. Our house is not too open plan, open plan houses are hard to heat and hard to cool, wonder why its the fashion, well its cheaper for the builder not building walls and putting on doors, leaving off eaves.
When I was a child in the UK we lived in Norfolk when I was very young and we did not have electricity, my grandparents who lived in a Mill House in Suffolk had gas lighting in those days. One thing though you could walk through the village and use the pavement it was not covered with cars.
