You could feel overwhelmed by the sheer quantity of alternatives while looking at the 3 Storey House plan. You must carefully consider your needs to determine which option best meets them. Design considerations for a three-story home may include a garage with room for up to five cars on each level (including the ground floor), a level accessible from the alley or the back of the house for off-street parking, an open living area that flows into the kitchen, more than one full bathroom per floor, as well as additional features like a wet bar and family room.
