Construction on the castle is complete for now, but there's still room for growth in the future.

As the Children's Hospital was being built, Sanford officials considered how to incorporate the possibility for expansions. One of the options is to build to the north, onto the specialty clinic. Another option---go up and add two additional floors. If they did that, the blue turrets would be placed at the highest level of the hospital.

But at this time, they're no specific plans for future construction.
