This is traditionally a more formal area, but today it is becoming smaller and less important than the family room. The living room is generally used for evening entertainment and therefore obtaining a view from this area is less important than that of the family, meals or kitchen areas.
Always choose a bedroom size that will suit your future needs. Children require a desk for study, and this is best in their own environment, namely their bedroom. Some children like to display their own craft-making abilities, plastic models, sculptures, mobiles, jigsaw puzzles, games, doll's house or train sets. All these require space in the bedroom.
The master bedroom should be large enough to contain a king size bed, dressing table, chair, bedside tables and perhaps a chest of drawers. The master bedroom should contain either a walk-in dressing area with robes, or at least built-ins. These are cheaper to provide in a new home than new furniture.
