Many Australian families are probably already aware that Generation Y children are quite comfortable with continuing to live at home well into their 20s.

Research from McCrindle Research, as reported in the Sydney Morning Herald (SMH), has shown that up to 25 per cent of children between the ages of 20 and 34 still live at home with their parents.

Social researcher Mark McCrindle tells the SMH: "Having spent many years in their parents' well-established homes, Generation Y has grown accustomed to a high standard of accommodation and is now demanding well-located housing that is also spacious and affordable."

Of course, many parents are more than happy to continue living with their children and maintaining the family unit under one roof.

In these cases, some households may wish to think about making changes to their home in order to better facilitate the lifestyles of parents and their adult children.

In the interests of giving everyone their own space, a well-timed renovation project can increase the ease with which families live together.

Second bathroom installations are a great place to start - bathroom renovations can turn a laundry into a more functional space complete with shower, basin and toilet.

By avoiding a bottleneck - especially in the mornings - families will find that the second room makes for a smoother operation.
