I'm planning to add a 10-foot railing to a patio that has a 6x6 wood post on one end and the exterior of the house on the other end of what will be the railing. I'm planning wood horizontal rails (maybe 2x4s) with vertical bars (wood or metal) connecting them. How should I connect the horizontal wood rails (upper & lower) to the painted wood exterior of the house, and also to the 6x6 painted wood post (which is house-high and supports a patio roof)? Should I use pocket holes, a bracket of some sort...? I'd like it to look good and be secure, and last at least 10 years if not more. Happy to spend a little more for a better connection. Must be easy enough to do myself (home improvement newbie).
Update (additional detail):
Patio floor is concrete slab/foundation (same pour as for entire house). The railing will protect against a drop-off of about 20 inches (code requires railings above 30 inches) but where the ground below is an asphalt brick walkway. I would like to avoid drilling into the slab (definitely if I keep the project DIY).
