Not sure if this question belongs here... but don't see anywhere else to ask it, so here goes. I am about to build a patio out back, and will need to build a deck. I will need to get this thing as low as possible (house is on a slab) and will basically need to build the deck on a sleeper system that will be laid on the ground. Swmbo wants the deck material to be out of wood or something like trex. So my basic question is, all things being equal (cost is not a significant concern)... should I use Ipe or some other semi exotic wood or trex for the deck. I only want to do this once, so this is gonna have to last for about 30 to 40 years. Due to extremes in weather out here (high desert of so cal) redwood or cedar are out of the running, and pressure treated material in exposed conditions is not gonna cut it with the wife. So what would you do? Thanks in advance for your input.
