With an additional floor, which is often referred to as a “pop-top” addition, the roof lines can be made steeper while the sizes and shapes of the windows changed. In general, building upwards won’t change the existing footprint of the home. In most cases, the first floor houses the living and dining areas while the upper floor is used for bedrooms but the options are endless.
If you plan to build outward and add a same-level L-shaped wing at the side or rear of the home, the roof lines can extend and match the present roof. In general, adding an outward addition on a ranch-style home is less expensive than a second story and you won’t have to find other living quarters while the work is being carried out. In addition the outdoor living area can be expanded at the same time with a courtyard or a sun room is also an option.
