It was an interesting scenario. Our Headquarters was located on the same lot as our current house now, but they are/were separate buildings. In the early ninties, we raised approximately $5,000,000 for our new Administrative Office, located a mile or so off campus, on about 8 acres of land - truly a sight for sore eyes. Anyway, the chapter now occupies both buildings on their lot, one is the main house and the smaller (old Admin. Office) is now living quarters.
