The familiar exterior of this plan leaves you completely unprepared for the totally unpredictable interior. No fewer than three stairways connect the main floor with the two supplemental levels. The master suite has a private stairway to the enormous office overhead, and a convenient kitchen stairway ascends the nearly 40-foot game room that completes the second floor. The expandable lower level contains a huge garage, storage area, bath and storm shelter. The three secondary bedrooms are clustered on the main floor, with two baths.
