Beautiful. That deck must cost more than some homes!! Ipe is really toxic. But may be more applicable when sanding. Again, nice work. Hopefully, the break includes a dip in the pool.
With recent lumber prices, PH is actually more economical. I bought it for $2.20 a LF for 1x6". When you consider the 30 year lifespan compared to treated pine, it really is less money in the long run. Trex is something like $4 to $6 a LF, so it's even less than composite, and I believe much more beautiful.
If anyone is considering a Brazilian hardwood deck (IPE, PH, Tigerwood, Cumaru, et al) I would suggest you contact Sam at Brazilian Wood Depot in Georgia. Super helpful and prices can't be beat.
