How To I Control A Passionfruit Vine

Question

I’m rebuilding my home in the Bahamas, following the effects of Hurricane Dorian and I would like to include a passionfruit vine “tunnel” to the side door to the house (a distance of about 15m). I intend to build a pergola structure parallel to the side of the house. Upright 4×4 posts will be set in concrete, about 1.5m out from the line of the side of the house. They will connect at the top to horizontal beams resting on brackets on the wall. Strong wire will span between the posts and beams. The vines will be rooted in block and render planters about 1m. deep, positioned between the posts. I plan to plant a mix of Panama Gold and Panama red varieties. My questions are these; (1) What would be the recommended distance between posts? (2) Is the suggested depth of the planters suitable? (3) Is there a clever way to prevent the vine tendrils from “attacking the soffit or any other vulnerable part of the wall or roof? Very many thanks for any advice! Ian
