There have been an increasing number of second story additions coming through our office lately with most of them being in the City of Atlanta. As more people are moving to these neighborhoods and wanting to add on, the only solution is going up and adding another floor on these small lots.
Careful planning is required including a structural engineer to evaluate the existing foundation. It is also necessary to take into account cost to minimize additional structural and foundation costs. The foundations on these older homes are generally adequate, however the design must take into account getting the additional loads to the right locations on the existing foundation.
Not only is a second floor being added, but the entire house is undergoing renovation and retrofit.
