Bed and Bath
It has become normal for many people to consider that each person living in their dream home have their own bed and bath, but space could quickly become an issue. For a family with three children, they would now need three regular bedrooms that each has their own bathroom, and then there is the master suite to consider. Planning all these rooms can be a balancing act between space and money, so finding a good interior designer could be the best investment yet.
Closet space and storage have become issues in the modern world, and those are additions that need consideration when planning where the family will have their private spaces. Children today might gather in the kitchen with their parents for homework and meals, but they need a place where they can store their clothes, their electronics, and their sports equipment. The rooms should be of good size for resale value when the children move out, but they should not be quite as large as the master bedroom suite.
