This statistic seems unbelievable to me on a few dimensions, but it is still worth thinking about:
The National Association of Homebuilders predicts that by 2015, 60% of new homes will be designed with “dual master bedrooms.”
From a CNN.com article called “Options for Your Mediocre Marriage.” One option:
If it’s possible, consider separate bedrooms. You’d be surprised how the creation of privacy and nonmarital spaces in a marriage might help. Already one in four Americans sleep in separate bedrooms or beds from their spouses.
Even if the 1 in 4 number is true (and that includes separate beds, not only bedrooms), I wonder how that translates into demand for a 60% supply of “dual masters.”
