The best way to make small or cramped rooms larger is to remove a wall between adjoining rooms. You’ll not only create a larger, more useful floor area but also give your home a feeling of spaciousness.  The improved flow of traffic between rooms is another benefit, especially for homeowners who enjoy entertaining and families with children and pets.
