We're considering building a high deck off our house. It will have a high end (14 feet) because the yard slopes. We need to secure tall posts onto the slope, secure enough to support the weight of the deck. Has anyone here done this sort of thing before? If we didn't have so much height involved this would seem simpler. Since it's so high we may build a shed under the flatter part. Anyone have plans or ideas on how to do this?
