Chi, I've always been curious about this house. Kindly share its history/story :) Thanks for sharing. 
Haven't done complete research on this one, but the house is at the corner of Gaerlan and Sepic Roads.
I've heard that the Arevalos are the descendants of the late Benguet Governor Gaerlan whose official house used to seat at the current location of the Baguio City High School.
