How would I sum up a field from one opportunity record type and display it on another?

Hi all, I am in the process of implementing a protfilio opportuntiy record type. The parent opportunity record will display some of the attributes of the child opportuntiy records, specifially the property square footage.  How would I go about summing the propety square footage from the child opportunity records to the parent portfolio record? Thanks!

I would use triggers to implement your logic, i don't think it is possible to implement declaratively.
