Your needs vary significantly based on your season of life, and it is important to choose a house plan that is an appropriate match. Young families should choose a house plan appropriate for children. Features you might consider: a large and child-friendly yard, bedrooms on the same level, and plenty of room for play. A family with older children might like a downstairs den with bedrooms that allows for teenagers to have their own area. A retired couple might want a one-level home, where all the rooms are easily accessible and affordable to heat and cool.
