I am building an Ipe deck that is going to between 12 and 16" off the ground. I have the concrete piers poured already (36-42" deep, 8" sonotubes). I will be using 4/4x6 Ipe over a PT frame (southern yellow pine, acq I believe).

Because of the tight space, I am thinking of using three 2x6s laminated with plywood, construction adhesive, and screwed together for the beams, attached to 6x post anchors directly to the piers. Then laying 2x6 joists 16" o.c. over the top. That will give me the required height. Will that be strong enough to prevent any flexing?

The deck will only be attached to the house at one corner, for about 5'x5', the rest will be open for ventilation (the whole deck is about 400sf). Should I use 2x6 rim joists and cover them with 4/4x6 Ipe, or maybe use 2x6 Ipe lumber for the rim joists and eliminate the fascia boards? Will 2x6 rim joists look too thin? I am planning on putting a 45' angle on the beams to make them less visible from the sides of the deck, but I'm concerned that they not be too visible. If I use 2x8 or 2x10 rim joists, it seems like I will have too little ventilation underneath if the rim joists come that close to the ground.

I am building in Denver, CO so the climate is generally very dry. I plan on using #8 ss screws, which I gather will help prevent cupping. Any other suggestions?

Thanks, this forum has been really helpful so far.
