The front of the house gets baked by the afternoon sun. So, the use of pressure treated wood for decking and treads would take a beating out there. Composites might not check and crack like PT but the amount of expansion from the heat would be a issue. So, I guess the tried and tested material for this area is cypress. Cypress is indigenous to Northern Florida and for many years was a big part of the local economy until it was depleted. Like cedar, cypress belongs to the family Cupressaceae. Both share the same rot and insect resistance property that make them so appealing for use as a building material.
The framing material is pressure treated southern yellow pine.
I used some roof membrane to water proof the top of the 6 x 6 perimeter beam.
