The New York Times last week published a survey by the National Association of Home Builders which showed that contractors and architects predict 60% of all US custom-built properties will have sub-divided or separate master bedrooms by 2015.
Problems with snoring and differing sleeping patterns were cited as the main reasons for this trend.
But with the cost of land being so high over here, UK experts say there is likely to be more call for building upward than outward.
David Birkbeck, chief executive of the cross-industry not-for-profit organisation Design for Homes, says: “Britain has the smallest average room size in Europe, and because land is so expensive we are seeing increased demand for building upwards to create more space.”
Birkbeck says that vertical separation of bedrooms in family homes is often more successful because it offers occupants more privacy, as teenagers can enter at the ground floor level late at night without disturbing their parents upstairs.
Likewise, parents don’t need to worry about marital sounds penetra-ting the walls.
He adds: “It seems that we have the opposite problem to the US, as one house builder recently informed me he had found the perfect way to hang a door so as to provide couples with the extra few seconds necessary to pull the sheets up should someone want to enter the room unexpectedly.”
