A report came out in the media this week about what Australia might look like in the year 2050, with some big lifestyle changes coming as our population grows to a predicted 36 million. One of those big changes will be higher density housing, and more people living in very close quarters. Rod Simpson, the architect who developed Sydney's green Olympic village concept, said housing shortages in cities could be fixed if every new home had two kitchens and two bathrooms, allowing for two families to live under one roof. And another expert suggested that different generations of families would be more likely to live together ... parents, grown-up children and grandparents.

• I'd like to hear what you think about that idea. If you're an adult who moved out of home long ago, how would you feel about living with your parents or grandparents again because of the high cost of housing?

• Perhaps you already fit this picture.  Have you stayed living with your parents long after you thought you'd move out, because of the cost of housing?

• If so, if you been sharing a home with other generations or branches of the family, Tell us about your experience. Is it a battle to get some privacy? Do you get sick of living in each others pockets?

• Or is it a positive experience for you?

• Of course the concept of single people living on their own, and the expectation that each individual family should have their own home, is quite a modern Western trend... In a lot of other parts of the world three generations of a family living together is still quite the norm...

• If you're from a culture that is accustomed to everyone living under one roof, give us a call and tell us your experience. Do you feel you're missing anything by not having a home to yourself? Or do you gain an extra level of closeness to your family?
