I think it's a beautiful house. Having the family bathroom near the children's bedrooms is pretty common in floorplans, at least in Australia. They have a wardrobe between them and the kid's room which would mean an insulated wall, soft clothing that would muffle sound, and then perhaps sliding wardrobe doors. That might help. We have a similar format in our house, but a dressing room in place of the wardrobe. I suspect that once kids are old enough to be aware, parents are typically a lot more careful with their timing...
