Assuming there is enough available FAR. Does anyone have a ballpark figure, even experiences, adding another floor to the top of a house?

It may not need to be a whole floor but a large 17×20 room, with bathroom.

  1. I have a 3 story frame house, and am adding on a 3 floor extension on the back. Frame houses tend to have small foot prints for the standard 100 ft. lot, my architect was able to draw up a plan in which I am effectively doubling the size while more than adhering to FAR.
    Consider extending backwards and not upwards.

  2. i used to own a frame house and my architect did plans to do a mezzanine floor because you cannot add another floor to a frame.

  3. There are also fire code rules in addition to FAR rules about how many stories a wood frame can be, which I think is 2 stories for the combustion rating.
