1 Hiring a remodeling contractor to build a second floor addition can run $100-$300 a square foot for the typical addition (2-3 bedrooms and a bath plus a flight of stairs), but can go as high as $400-$500 per square foot depending on complexity, quality of materials and local labor rates.uilding a second floor (also called a second story) can added much-needed space, but costs at least 20 percent more than building the same square footage at ground level. However. if you don't have the land to build out it can make sense to go up. Typical costs:
1 Custom borders and patterns can look fantastic but bump up installation costs by $1-$2 or more a square foot, adding at least $144-$288 for a 12x12-foot room. 2  The more custom the project, the higher the additional expense. New wood flooring should be stacked inside the room for up to a week before installation to allow it to adjust to your home's indoor humidity level. 2  Always buy a waste allowance of 5 to 15 percent extra, depending on the project's complexity.
